Abstract/OtherAbstract:
|
Single neurons in the dorsal lateral suprasylvian cortex (DLS) of the cat were tested with large field optic flow stimuli simulating translation and spiral motion (including radiation and rotation) in different directions. Most cells were responsive to both kinds of movement with fairly good direction selectivity. Generally, the responses were better to spiral motion than to translation, and better to radiation than to rotation. Moreover, the direction tuning for spiral was broader than that for planar motion. The dot size in the stimulus patterns had no certain influence on the responses and direction preference. These results suggest that DLS might be substantially involved in the detection and analysis of complex optic flow information, and to some extent, in favor of the radiation component inside. |
