David Hubel and Torsten Wiesel demonstrate how individual neurons in the primary visual cortex of a cat respond to specific visual stimuli.

This a video showing Hubel & Wiesel in their famous experiments on visual neurons of cat. In this video they are demonstrating the simple and complex cells.

What people say. Recommended as a demonstration of how simple cells in the visual cortex respond to light bars and edges.

Here is a link to this video of a Hubel & Wiesel experiment from 1965 in the visual cortex. The video shows the experimenters outlining the receptive field of a simple cell in the first part of the video using symbols. Crosses are used for excitatory responses, and triangles for inhibitory responses. As shown in the video, neuron firing rate increased when the edge of a bar of light touched the crosses present on the top left. It is not just the orientation and location of light bar, but it seems that the light bar's edge is defining the firing rate, and thus determines the receptive field. So, the oriented receptive field of the cell seems to be defined w.r.t to the stimulus edges, rather than the…
