The biphasic temporal filter (upper left) is the difference of two
Maxwell functions. The temporal filter is multiplied by the spatial
Gabor functions (lower left) to produce the 3D spatio-temporal filters
(cross-sections shown at upper right).
The visual stimulus is processed (convolved) by two space-time
separable linear filters and the outputs are squared and added
(right). The result is scaled and used to drive a Poisson spike
generator, and a temporal delay is added to the spikes to simulate
visual response latency.
