Orientation and Direction Selectivity of Neurons in V1 of Alert Monkeys: Functional Relationships and Laminar Distributions

We studied orientation selectivity in V1 of alert monkeys and its relationship to other physiological parameters and to anatomical organization. Single neurons were stimulated with drifting bars or with sinusoidal gratings while compensating for eye ...

Local cortical lesions abolish lateral inhibition at direction selective cells in cat visual cortex

Many cells in the cat visual cortex display a strong selectivity for the direction of motion of an optimally oriented stimulus. Postsynaptic inhibition has been suggested to generate this direction selectivity in simple cells, but the intracortical p...

Recurrent Excitation in Neocortical Circuits

... into models of cortical direction and orientation selectivity that emphasize the basic design principles of cortical architectures. ...

Orientation selectivity in visual cortex by fluctuation-controlled criticality

... the effect of strong recurrent excitation on orientation selectivity. Previously, we showed that, using a strong network inhibition countered by feedforward and recurrent excitation, the cortical model reproduced many observed properties of s...
