Retina in Ink

Ink on watercolor paper

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.

Local Connectivity

22K gold, horse and synthetic human hair, ink, and dye on stainless steel

Framed in custom selected molding

The brain’s characteristic circuitry involves both long range, myelinated axon bundles (depicted with horsehair) that connect disparate regions of the brain and peripheral nervous system, as well as a great deal of locally connected circuits (inked neurons). These shorter range circuits are arranged into processing loops between excitatory and inhibitory interneurons that process and integrate information from various sources and arrange it for output.

This painting has a dynamic reflective element in the different lusters of 22K gold leaf overlaid onto etched and dyed stainless steel. It is best illuminated with a hard overhead light source such as a halogen or strong LED bulb that highlights its contrasting reflective lusters.

Framed in custom selected molding.
High velocity axons increase their transmission speed through the insulating properties of enwrapped membranes, a process called myelination. Cells called oligodendrocytes (dark grey) wrap their fatty membranes around axons (12K white gold) to prevent ion leakage which would dilute action potential efficiency. Arranged like the rings of a tree, these bundles of fatty membranes abut one another in beautiful chaotic patterns that emerge from the dense packings of fibers in white matter tracks.
This painting features gilded, hand etched laser cut acrylic pieces assembled and sealed with an enveloping gloss clear coat. It is designed to be illuminated from above with a hard light source such as a halogen or strong LED bulb that highlights the dynamic reflective patterns arising from the etched gold surfaces.

Neural Migration

Neural Migration depicts a period of brain development wherein radial glia (black cells) divide continuously to create new neurons (white cells). These new neurons climb the black dendritic stalks of their parent cells, eventually finding their final resting places within the layers of cerebral cortex. This process creates billions of new neurons and occurs over the period of only a few weeks during gestation.
