Enclosed are movies of intracellular recordings from either single relay cells during spontaneous intrinsic oscillations, or during the generation of spindle waves.

In addition, there are movies of the response of cortical neurons to current pulses or the presentation of a visual stimulus.

These movies are highly instructional in that they give a real time "feel" for how these cells behave. They are present in three formats: Video for Windows (*.avi), Quicktime (*.mov) and MPEG (*.mpg).
