Responses of single neurons in cat visual cortex to a simple and a more complex stimulus.

JONES, B. H. Responses of single neurons in cat visual cortex to a simple and a more complex stimulus. Am. J. Physiol. 218(4): 1102-l 107. 1970.-The response of a single neuron to an oscillating light-dark edge in the visual field (simple stimulus) was compared to the response when a second edge was added at a variety of distances from the first (complex stimulus). It was found that the second edge often influenced the response to the first from positions beyond the apparent receptive field limits. Response to one edge could be augmented or diminished by the addition of a second edge, but the response to the more complex pattern was not predictable from the response characteristics for the simple pattern.
