Neural integration and enhancement from the inferior colliculus up to different layers of auditory cortex.

abstract：:1. Responses of complex cells in cat striate cortex were studied with flashed light slit stimuli. The responses to slits flashed in different positions in the receptive field were assessed quantitatively before and after periods of prolonged stimulation of one small region of the receptive field. This type of prolonge...

Whole cell patch-clamp techniques, combined with direct visualization of neurons, were used to study voltage-dependent potassium currents in layer 1 neurons and layer II/III pyramidal cells. 2. In the presence of tetrodotoxin, step depolarizations evoked an outward current. This current had a complex waveform and a...
