Imaging the Brain: David Gappa's installation at the University of Texas uses glass and light to illustrate synaptic firing
A synapse is the structure that connects neurons in the brain, linking then together so that electrical signals can be transmitted to create thoughts, memories, and experiences. A single synapse can fire 50-times a second, a sequence that is multiplied for hundreds of trillions of times during the normal synaptic functioning in the brain. If this is hard to conceptualize, artist David Gappa created a visual tool to illustrate. The result of Gappa's efforts is Introspection, a massive light fixture illuminating the room with a vibrant luminescent display, Each flicker, pulse, or flash of light in the over thousand hand-blown glass objects shows the viewer what a group of synapses does a billion-times an hour. His largest creation yet, the monumental work was unveiled on October 12, 2017 at the University of Texas' Brain Performance Institute. …
