Abstract
Contextual modulations of receptive field properties by distal
stimulus configurations have been shown for a variety of stimulus
paradigms. A survey of excitatory contextual modulation data for V1 shows
the maximum scale of interactions, measured in terms of distance in V1, to
be between 10 mm and 30 mm. Different types of excitatory contextual
modulation in V1 occur throughout the interval of 40–250 ms after
stimulus delivery. This window provides opportunity for global propagation
of visual contextual information to a subset of V1 neurons, via several
routes within the visual system. We propose a number of experiments and
analyses to confirm the results from this empirical survey.
