Translations:Orientation Selective Ganglion Cell/11/en

It is hypothesized that the initial hyperpolarizations recorded are caused by the field peripheral to the center. The length of the slit of light was reduced, and it was found that the hyperpolarizations decreased in amplitude. When the slit of light was reduced to 300 micrometers there was an initial hyperpolarization, but the sustained hyperpolarization was replaced by depolarization. At 225 micrometers, the hyperpolarization response was no longer found and the orientation selective ganglion cells did not show a preference to orientation with this stimulus. This means that inhibition from the peripheral region of the receptive field is necessary for orientation selectivity
