Attentional modulation in layer 4 of the visual cortex could be mediated by interneurons with complex receptive field characteristics
Paul H. E. Tiesinga, Calin I. Buia
Many neurons in the visual cortex are orientation-selective, increase their firing rate with contrast and are modulated by attention. What is the cortical circuit that underlies th…

Attentional modulation of firing rate and synchrony in a model cortical network
Calin Buia, Paul Tiesinga
When attention is directed into the receptive field of a V4 neuron, its contrast response curve is shifted to lower contrast values (Reynolds et al, 2000, Neuron 26:703). Attention…
