Cortical Circuitboard features a stylized array of cortical neurons that are arranged into the layered structure of the cerebral cortex.  We incorporated aesthetic motifs drawn from circuitboard design into the neural landscape to draw parallels between the chaos of a biological brain and the order of an electronic one.
This piece features the first example of Dr. Edwards’ animation algorithm.  Using visual information built into the design, Dr. Edwards wrote a program that calculates the precise angle necessary at any coordinate on the microetching to reflect light to the viewer standing at a given position.  This allows light to reflect off of the surface in specific ways, giving us the ability to depict animations within each neuron.  As the viewer walks past the microetching the neurons fire action potentials, creating a finished piece whose circuit dynamics represent the actual firing patterns found within the cerebral cortex.

Cortical Circuitboard is framed with a beautiful dark wood moulding and comes with a custom built solid brass lighting fixture that affixes to the top of the frame that is optimized to highlight the reflective animations.  A fading mechanism is built into the unit to allow the light to be adjusted. If desired, the piece can be displayed with multiple lighting sources for a multicolor effect. Color, as it is in all microetchings, is very flexible variable.
