TI  - Responses of monkey inferior temporal neurons to luminance-, motion-, and texture-defined gratings

N2  - 1. We recorded from neurons responsive to gratings in the inferior temporal (IT) 
cortices of macaque monkeys. One of the monkeys performed an orientation
discrimination task; the other maintained fixation during stimulus presentation. 
Stimuli consisted of gratings based on discontinuities in luminance, relative
motion, and texture. 2. IT cells responded well to gratings defined solely by
relative motion, implying either direct or indirect motion input into IT, an area
that is part of the ventral visual cortical pathway. 3. Response strength in
general did not depend on the cue used to define the gratings. Latency values
observed for the two static grating types (luminance- and texture-defined
gratings) were similar, but significantly shorter than those measured for the
kinetic gratings. 4. Stimulus orientation had a significant effect in 27%, 27%,
and 9% of the cells tested with luminance-, kinetic-, and texture-defined
gratings, respectively. 5. Only a small proportion of cells were orientation
sensitive for more than one defining cue. The average preferred orientation for
luminance and kinetic gratings matched; the tuning width was similar for the two 
cues. 6. Our results indicate that IT cells may contribute to cue-invariant
coding of boundaries and edges. We discuss the relevance of these results to
visual perception.
