The video is definitely out of sync (which does defeat the purpose once you know what's going on). Search Google for hubel and wiesel video for a .mov copy of the original and go to 4:10 to see this clip.
By presenting bars and edges of both increments and decrements of light luminance, this person is mapping out the visual area over which this cell is active (produces action potentials, those blips you hear).
This person is either David Hubel or Torsten Wiesel and has an anesthetized cat with it's eyes pointed toward this screen. An electrode is placed in the occipital cortex in the first part of the neocortex that receives visual information from the eyes via the thalamus. This electrode picks up the electrical signal of an action potential, which signifies the information that a particular neuron in this area is passing on to other neurons.
I think the dubbing is slightly out of synch, therefore slightly defeats the objective of the video. However I think this is Hubel and Wesel's classice experiment depicting the orientation specific bar Simple Cortical Cells
I can't see any connection between the video and the audio.

The 'x' represents on area and the triangle represents off areas.

Fascinating. What do the "x"'s and triangular markings signify?
