Attention and primary visual cortex
Year: 1999
Type: article
Abstract: Evidence for attentional modulation of responses in primary visual cortex has been a matter of considerable debate. The classical notion concerning attention effects in visual cortex has held that the strongest effects are seen at the highest levels of the visual pathway, and that in primary visual cortex there is no effect of attention. The report by Somers et al. (1) of a functional MRI study indicating primary visual cortex (V1) modulation by instructions to attend illustrates the change that has taken place in recent years. This commentary expands on that theme by providing some of the history of work related to attention and V1 and by citing new studies of V1 modulation that use a variety of methods.
