abstract = {In natural vision, neuronal responses to visual stimuli
occur due to self-initiated eye movements. Here, we compare
single-unit activity in the primary visual cortex (V1) of
non-human primates to flashed natural scenes (passive vision
condition) to when they freely explore the images by
self-initiated eye movements (active vision condition).
Active vision enhances the number of neurons responding, and
the response latencies become shorter and less variable
across neurons. The increased responsiveness and shortened
latency during active vision were not explained by increased
visual contrast. While the neuronal activities in all layers
of V1 show enhanced responsiveness and shortened latency, a
significant increase in lifetime sparseness during active
vision is observed only in the supragranular layer. These
findings demonstrate that the neuronal responses become more
distinct in active vision than passive vision, interpreted
as consequences of top-down predictive mechanisms.},
