Effects of LSD on the responses of single units in cat visual cortex

... simple cells. Changes in spontaneous activity, direction selectivity and orientational properties were found in some cells....

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

... inhibition has been suggested to generate this direction selectivity in simple cells, but the intracortical pathways involved have not been identified. While continuously recording from simple cells in layers 4 and 6, we have inactivated the super...
