Increasing stimulus size dramatically increases neuron selectivity, precision, and reliability
Figure 4. A-C. Example responses to repeated presentation of a natural movie that was either 1X, 2X or 3X the CRF in size. Note the response at 3X is to a smaller number of frames of the movie and that the discharge is more precise in time and shows less trial to trial variability (it is more reliable). D. The measure of sparseness is greatly increased by enlarging the stimulus area.
