The animated reflective microetching Brain Machine Interface is a piece about the interconnected future of the human brain. It simultaneously comments on both the amazing benefits and potential dangers of these powerful neural interfacing technologies, and will hopefully serve as a reminder to humanity to proceed with cautious optimism.

As the viewer moves from the left to the right of the etching, neurons synapse into and create a face initially with a terrified expression. This symbolizes the average person’s fear regarding the future of human/machine evolution, particularly concerning the more invasive implant technologies currently being utilized. The etching then transitions into an expression of awe, relief, and joy upon their successful implentation – restoring lost functionality, enhancing human cognition and communication, greatly increasing our access to information, etc. Finally, circuits spray out of the face and symbolize this evolution toward enhancing human potential.
Upon viewing the etching from right to left, however, the opposite progression unfolds: humanity achieving a godlike state through the use of these technologies only to fall victim to unwise misuses that lead to a degradation of the human soul.

These are 24″ X 32″, 22K gold hand-gilded etchings framed with anti-reflective and UV protective glass in a beautiful dark wood molding. The original etchings come with an optional light source which wraps around from the back of the frame and illuminates the piece with a single white light. Multicolor illumination is not included in the price, but if desired I can advise on the best ways to achieve it. I highly recommend track lighting to illuminate Brain Machine Interface as it is the simplest and most flexible lighting system and is capable of the most dramatic visual effects. All shots taken in the video below where the camera is moving were made using a track lighting system. You can read more about how to illuminate microetchings in this PDF here.
Each microetching is made when ordered and will be available for delivery in approx 4-8 weeks.

Additional information on lighting, etc.

Both 22K original microetchings and microetched prints can appear dramatically different depending on how they are lit, and below are a series of still images demonstrating suggested illumination patterns. The more lights you have on the piece, the more “pulses” of illumination you will have.

Microetchings are not static pieces of art. Please watch the video below to see Photosynthesis’ full potential.




























Photosynthesis from Greg Dunn on Vimeo.

Photosynthesis is a work combining both art and science to simulate how water and nutrients are transported through the vasculature of a leaf. These processes represent basic functions of plant physiology which are invisible to the unaided eye. The pulsing flow traveling through the leaf’s circulatory system makes this etching quite mesmerizing to behold.

Science Friday: Etched From The Mind http://www.gregadunn.com/news-about-greg-dunn-neuroscience-art/science-friday-etched-from-the-mind/ Mon, 15 Apr 2019 21:52:30 +0000 http://www.gregadunn.com/?p=9423 Original article link: https://www.sciencefriday.com/videos/etched-from-the-mind/
by Luke Groskin, Johanna Mayer, on April 15, 2019

For Greg Dunn, an artist and neuroscientist, “the brain is a sacred object and I think deserves to be treated as so. It’s responsible for our entire existence.”

Often with his colleague Brian Edwards, Dunn makes “microetchings” which depict the brain and its neural processes. He begins by making a traditional ink drawing, which he then scans into a computer. Dunn then prints the etching data onto a transparency and laminates the material onto a sheet of steel.

While studying neuroscience in graduate school, Dunn began to experiment with science-inspired art. When he spent his days in the lab, he realized that he was surrounded by stunning imagery every single day—it was all under the microscope. He began to simulate what he would see on the page, in the style of Japanese and Chinese ink drawings. Dunn wanted to draw parallels between the classic subjects of eastern Asian art, and the expansive world of neurons.

“The only difference between a landscape of a forest and a landscape of a brain is that you need a microscope to see one but not the other,” says Dunn.

By couching his depictions of neurons and the brain in an aesthetic style that many people recognize, people could make those connections themselves, he says.

A 16th century Japanese sumi-e painting by the Japanese artist Sōami.

 

To depict a neuron firing, Dunn uses gold leaf and manipulates the reflectivity of the metallic surfaces. He and Edwards also dabbled in etching and lithography, and used the technique to create millions of microscopic details in the surface of a microetching, all of which reflect the light in highly specific ways.

“Our minds and our brains are the fundament of who we are as human beings,” Dunn says. “It’s a concrete processing device which allows us to go about our daily lives. And I think it’s important that people understand that, and recognize the preciousness of their own brains.

Oh Chouette: Ces images cérébrales montrent la beauté et la complexité de la conscience humaine Publié http://www.gregadunn.com/news-about-greg-dunn-neuroscience-art/oh-chouette-ces-images-cerebrales-montrent-la-beaute-et-la-complexite-de-la-conscience-humaine-publie/ Sun, 15 Jul 2018 21:30:56 +0000 http://www.gregadunn.com/?p=9416 Link to Original article: https://ohchouette.com/ces-images-montrent-la-beaute-et-la-complexite-de-la-conscience-humaine/

Publié par , le mardi 17 juillet 2018 à 8:01.

L’Univers a toujours été synonyme de beauté et de complexité. Que l’on se dirige vers l’infiniment grand, ou que l’on plonge au cœur de l’infiniment petit, le degré d’émerveillement reste le même. Le plus fascinant dans tout cela, c’est de voir la similarité qui existe entre la structure de l’Univers et celle du cerveau humain…

Lorsqu’on parle de cerveau humain, on tend à imaginer l’organe tel qu’on le voit de l’extérieur. Mais, vous êtes vous seulement demandé à quoi peut-il ressembler vu de l’intérieur ? Ou encore, avez-vous une idée de ce à quoi peut ressembler le fin fond de notre conscience ?

Un groupe de chercheurs ont justement travaillé dur pour nous le montrer. En associant Art et Science, ils nous offrent les images les plus bluffantes illustrant l’activité cérébrale.

Entre beauté et complexité

Le cerveau est l’organe qui suscite le plus la curiosité des médecins et des scientifiques. Avec ses centaines de milliards de neurones, et les millions de connectivités qui existent entre ces derniers, il constitue un chef-d’œuvre à la fois complexe et cohérent dans les moindres détails.*

Afin de représenter notre système neuronal, et de montrer au grand public la beauté qui existe en chacun de nous, Greg Dunn, Docteur en neurosciences, s’est lancé dans le projet fou de réaliser des images animées en 3D illustrant la manière dont plus de 500 000 neurones prennent vie.

En moyenne, 700 nouveaux neurones naissent chaque jour dans notre cerveau. En s’associant avec son collègue Brian Edwards, Greg Dunn invente la « microgravure », une technique qui permet de voir la création de la conscience en pleine action. Après deux ans de dur labeur, « Self Reflected » a vu le jour.

Self Reflected est un autoportrait en 3D qui permet à l’observateur de voir l’activité de son cerveau au moment même où il le regarde. Comme son nom l’indique, il s’agit d’une sorte de miroire qui reflete la conscience.

Une technique qui donne vie à notre conscience

Le Docteur Dunn a commencé par recueillir toutes les informations dont il avait besoin sur le système cérébral. Pour ce faire, il a collaboré avec des scientifiques qui se spécialisent dans le domaine.

Il a utilisé des cartes du cerveau et des scanners, et il a développé un algorithme sophistiqué permettant de représenter les différentes courbures, et la façon dont les neurones s’activent. Le résultat est projeté sur un écran d’ordinateur.

Afin d’ajouter la touche artistique aux images obtenues, il les a imprimés sur des transparents, avant de les graver sur une résine photosensible en utilisant des techniques de photo lithographies, et les a fait passer à la feuille d’or. Des LED sont ensuite utilisées pour l’illumination, et pour un meilleur aperçu du mouvement.

Cette œuvre permet à la fois de visualiser la complexité et la beauté de notre réseau de neurones, et la façon dont celui-ci fonctionne. Le chercheur explique que l’algorithme choisit les classes de neurones à afficher de façon aléatoire, ainsi, pour chaque itération, de nouvelles images apparaissent, toutes aussi incroyables les unes que les autres.

The triggering of an action potential is one of the foundational principles on which the brain operates. Action Potential is an animated microetching that simulates how a neuron receives and integrates incoming signals from connected neurons to trigger an action potential. Incoming action potentials from the small neurons hit the dendrites of the large neuron while their collective input builds through the large neuron’s dendrites. When these signals simultaneously reach the cell body, they trigger the large neuron to fire its own action potential. While this piece is a study of how input velocities, locations, and relative strengths influence a downstream neuron’s ability to fire, it is also an artistic experiment exploring the explosive beauty of the process. Action potentials are the fundamental processes by which we think, feel, taste, and accomplish every task our brain carries out.

Both 22K original microetchings and microetched prints can appear dramatically different depending on how they are lit, and below are a series of still images demonstrating suggested illumination patterns. In these images, the colors encode information about relative locations of the synapses relative to the cell body. For example, the more proximal gold colored synapses may be contributing to a greater degree to the signal integration, whereas the more distant pink synapses may be contributing a weaker signal.

The blood brain barrier is the brain’s first line of defense, a selective filtering mechanism of the capillaries that prevents bloodborne pathogens, toxins, and other substances from entering the neural tissue. It is comprised of endothelial cells and astrocytes which create a tight restrictive boundary around the blood supply.

The painting is also a study in fluid dynamics to impart a more biological feel to the materials. Metal powders and dyes suspended in epoxy resins are applied to the canvas and torched to encourage chaotic elements to develop. The astrocytic cell bodies that extend their feet to the blood vessel boundaries are created by using rock salt as a mold around which epoxy layers are flowed, then dissolved out and filled with resins to emulate a more three dimensional feel to the painting.

Blood Brain Barrier features a reflective design that is best illuminated by a single overhead light source. Please watch the video for further demonstration.

    Drawn and etched with algorithms, Greg Dunn’s masterpiece is unique in more ways than one.

    Sometimes neuroscientist Greg Dunn finds his field tedious. Working at a lab bench can make you forget how beautifully ornate the human brain is, he says. To reinspire himself, his colleagues and the public, Dunn makes art. Most recently he made an eight- by 11-foot gilded engraving of the human brain.

    Titled “Self Reflected,” the piece maps Dunn’s illustrations of neurons and axons via algorithmically guided microetchings. As LEDs scan across the surface, they reflect off the varying depths and angles of the gold leaf grooves to make each neurological pathway shimmer like it is truly alive with electrical firings. The art is on display at The Franklin Institute in Philadelphia but videos like the one below are also on the project’s Web site. Watching the massive display composed of minute and intricate carvings is overwhelming—and that’s kind of the point, says Dunn, who received his neuroscience doctorate in 2011 but has dedicated his career to making art instead. “I wanted to use the power of art to communicate the complexity of the brain,” he says.

    Self Reflected – A Guided Tour from Will Drinker on Vimeo.

    To get his message across, Dunn first sketched out the clusters of neurons and the sweeping tails of axons according to descriptions given to him by other neurologists who specialize in the organization of different brain regions. His drawings, Dunn says, display the general layout of each lobe’s neurons—they are not based on any one person’s brain connectivity. The art became further randomized once Dunn handed the illustrations over to his algorithm. He wrote a code to sketch imitations of the overall structure of his drawings but instructed it to treat the neurons in each region as a giant connect the dots. Dunn could apply some parameters, such as how organized or random the path was, but otherwise left the computer free to design. Afterward another algorithm assessed each line for its distance from the LED lights. This code determined the angle and depth each groove would need to be struck to achieve different visual textures, such as the wavelike light reflection in the cerebellum or the more fractured displays of the frontal eye cortex. Dunn and his team printed the images onto transparencies they laid over a specific form of ultraviolet-sensitive polymer. In a process called photolithography, UV light etched the images into the underlying material.

    Although Dunn says his art is not based on any one individual and relies on the random choices of a computer, the final product is far from generic. If he reran all the algorithms that comprise the final product, he explains, the tiniest details of the engraving would be different. Macroscopically, the image would be organized the same way but within each tiny cluster of neurons the algorithm would choose a new route. This is the same level of divergence that distinguishes one person’s brain from another’s, he explains. “The devil is most definitely in the details,” he adds. Dunn’s art, then, displays not only humanlike complexity, but humanlike uniqueness as well.

    Pour représenter la complexité du système neuronal, Greg Dunn, docteur en neurosciences, a créé une technique de microgravure. 500 000 neurones prennent vie dans de très belles images.

    Le cerveau est un chef d’oeuvre de complexité. Les milliards et milliards de neurones qui le composent sont impossibles à compter, mais chaque jour, nous en fabriquons en moyenne 700 nouveaux… Indispensables, ils effectuent à chaque seconde une chorégraphie très fine et précise. L’américain Greg Dunn, docteur en neurosciences, a voulu élucider ce “mystère de la conscience humaine“. Artiste reconverti, il est l’auteur d’une représentation 3D de cet enchevêtrement prodigieux.

    Grâce à une technique inventée pour l’occasion avec son camarade Brian Edwards, docteur en physique, appelée la “microgravure” (microetching), Greg Dunn a pu modéliser environ 500 000 neurones. Le résultat ? “Self Reflected“, une oeuvre qui montre “le cerveau entrain de se concevoir lui-même“, un autoportrait qui veut “réfléchir le miroir du propre cerveau de celui qui regarde l’oeuvre“. Sur 25 plaques gravées, une coupe sagittale oblique de cerveau s’étend en 3D sur plusieurs mètres de longueur. En boucle de 500 microsondes (0,0005 secondes), les neurones prennent vie et frémissent grâce à des effets lumineux.

    L’oeuvre a mis 2 ans à être conçue. Se basant à la fois sur des scanners et des cartes du cerveau, Greg Dunn a collaboré avec des doctorants et des scientifiques spécialisés dans le cerveau. Grâce à des algorithmes, ils ont modélisé la façon dont s’anime le circuit neuronal. “Nous avons intentionnellement injecté du hasard dans nos algorithmes » pour mieux recréer les formes chaotiques des neurones. Avec ces recherches, il créé son oeuvre sur ordinateur. Imprimé sur des transparents puis “gravé” sur une résine photosensible par des techniques de photo lithographies, le résultat est ensuite passé à la feuille d’or. Une fois les 25 plaques installées, des LED permettent d’illuminer l’oeuvre, et de créer le mouvement. “A travers la très grande quantité de détails et cette simulation de l’activité des neurones, Self Reflected atteint un niveau de détails sans précédent“, explique Greg Dunn.

    This totally unique mash-up between neuroscience and art shows the stunningly complex beauty of the human brain. Your brain is terrifyingly complicated and is made up of approximately 86 billion neurons which work together as a biological machine to create who you are. But it takes some real cranium contortion to get your head around what those billions of signals and connected web of cells look like. Artist and neuroscientist Dr Greg Dunn combined talents with artist and physicist Dr Brian Edwards to produce this unprecedented work of wonder. ….

    Taking nearly two years to complete, artist and neuroscientist Dr. Greg Dunn, along with his collaborator Dr. Brian Edwards, have mapped the neurons in the brain for a series of images titled Self ReflectedProduced through a technique they call reflective microetching, the two cross-disciplinary artists track the neural choreography in the mind, creating brilliant images that glow with a metallic luminescence.

    The works depict a thin slice of the human brain at 22x the normal scale, each created through a combination of hand drawing, neuroscientific data, algorithmic simulation of neural circuitry, photolithography, strategic lighting design, and 1,750 sheets of 22k gold leaf.

    “My work is neonaturalist, art based on natural forms and influenced by scientific advancements that allows us to perceive the universe beyond human senses,” explains Dunn in his artist statement. “Neonaturalism harmonizes unfamiliar scientific imagery and techniques with an experimental artistic scaffolding.”

    Self Reflected was funded the National Science Foundation, and its first iteration is on permanent view at the Franklin Institute in Philadelphia, PA. Fine art prints and microetchings can be purchased on Dunn’s website. You can watch the work twinkle as it engages with a light source in the short video below. (via My Modern Met)

    ‘Self Reflected under white, red, and violet light’ is billed as ‘the world’s most elaborate artistic depiction of the human brain.’

    The artists drew on techniques from art and science to create the piece: neuroscience data, hand drawing, algorithmic manipulation, optical engineering, photolithography, gilding and more. They invented a technique called ‘reflective microetching’ to image half a million neurons on large sheets of gold.

    ‘Self Reflected’ was one of the winners of the 2017 Vizzies awards for scientific visualisation. The rest of the winners can be seen here.

Please contact me for information and pricing. 

    In addition, a very small number of the full size, 96″ X 130″ 22K gilded microetchings with customized lighting design will be available for sale to museums, institutions, and private collectors. Please contact me for information and pricing. 

    Dr. Greg Dunn (artist and neuroscientist) and Dr. Brian Edwards (artist and applied physicist) created Self Reflected to elucidate the nature of human consciousness, bridging the connection between the mysterious three pound macroscopic brain and the microscopic behavior of neurons. Self Reflected offers an unprecedented insight of the brain into itself, revealing through a technique called reflective microetching the enormous scope of beautiful and delicately balanced neural choreographies designed to reflect what is occurring in our own minds as we observe this work of art. Self Reflected was created to remind us that the most marvelous machine in the known universe is at the core of our being and is the root of our shared humanity.

    18″ X 24″
    2015
    $2500 SOLD

    Framed in custom selected moulding with antireflective and UV protective art glass.

    The retina converts light hitting the eye into neural signals that can be interpreted by higher order brain structures in the cortex. Light hits the photoreceptors (top of the painting) and the consequent signals transmitted through the retina are organized into packets of semiprocessed information that conveys the basic color and edge structure of an image. This is accomplished by the coordinated activity of the retinal layers, made of bipolar, amacrine, horizontal, and ganglion cells. After the retina, visual data is sent through the optic nerve through the thalamus and into primary visual cortex at the back of the brain.

    Retina in Ink is a neonaturalist work combining scientific visualization with techniques in abstract expressionism to yield chaotic and evocative neural networks in ink.
