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 position. Orientation selectivity based on spike counts was quantified by circular variance and by the… (More)
