| Research Abstract |
We examined the response selectivity to angles embedded larger than the size of classical receptive fields in primate V2 neurons under anesthesia. The study indicated that single side end-stop neurons represent one half-line component of the optimal angle and another component acted as a modulator to specify an optimal angle. Partial similarity of the angle selectivity indicated that V2 neurons inherited the selectivity of V1 neurons and produced more elaborate angle selectivity.
