A Model of Recurrent Interactions in Primary Visual Cortex

A general feature of the cerebral cortex is its massive interconnectivity -it has been estimated anatomically [19] that cortical neurons receive upwards of 5,000 synapses, the majority of which originate from other nearby cortical neurons. Numerous experiments inprimary visual cortex (VI) have revealed strongly nonlinear interactions between stimulus elements which activate classical and nonclassical receptive field regions.
