About it
From a concept by Ryan Kamp. A textbook nerve cell on a lit microscope slide: dendrites, a cell body with its nucleus and Nissl bodies, a myelinated axon, and terminals. At full Focus, most screens draw 32,768 splats, low-memory phones 8,192.
A tap is a stimulating electrode: the signal spreads through the dendrites to the cell body, which fires a spike down the axon, node to node. The waveform is the Hodgkin-Huxley squid axon model, slowed; this is a schematic, not a measured neuron. Nissl dyes the Nissl bodies and leaves the axon pale, Golgi turns the neuron black on amber, and H&E shows pink cytoplasm and blue-purple nuclei. Lower Focus: pairs of splats merge into one, keeping mass, center, and covariance, while the slide stays lit. Made by Ryan Kamp, CC0; code MIT.
