Correlation between the effects of attention and response normalization in prefrontal area 8A neurons is cell type dependent.

Many visual neurons lower their response rates to a stimulus in the receptive field when other stimuli are added inside or outside their receptive field. This phenomenon has been proposed to be the result of a canonical normalization mechanism that acts across multiple brain areas and has been reported to correlate with visual attentional response modulation in extrastriate visual neurons. We recorded neural activity in prefrontal area 8A, an...
