Increasing stimulus size dramatically increases neuron selectivity, precision, and reliability

Figure 4. A-C. Example responses to repeated prentation 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.
