On the velocity tuning of area 18 complex cell responses to moving textures
Unlike simple cells, complex cells of area 18 give a directionally selective response to motion of random textures, indicating that they may play a special role in motion detection. We therefore investigated how texture motion, and especially its velocity, is represented by area 18 complex cells. Do...

| description | Unlike simple cells, complex cells of area 18 give a directionally
selective response to motion of random textures, indicating
that they may play a special role in motion detection. We therefore
investigated how texture motion, and especially its velocity,
is represented by area 18 complex cells. Do these cells have
separable spatial and temporal tunings or are these nonseparable?
To answer this question, we measured responses to moving random
pixel arrays as a function of both pixel size and velocity,
for a set of 63 directionally selective complex cells. Complex
cells generally responded to a fairly wide range of pixel sizes
and velocities. Variations in pixel size of the random pixel
array only caused minor changes in the cells' preferred
velocity. For nearly all cells the data much better fitted a model
in which pixel size and velocity act separately, than a model in
which pixel size and velocity interact so as to keep temporal-frequency
sensitivity constant. Our conclusion is that the studied population
of special complex cells in area 18 are true motion detectors, rather
than temporal-frequency tuned neurons. |
