In the eyes of a cat

U of C grad student and former undergrad minion of mine Kyler Brown has a demonstration of the “Cat Cam” data over at Bytes and Spikes. The movie was created by attaching a camera to a freely roaming cat in a natural environment and playing it back to an eye-tracked cat. So you get both bodily motion and eye (and presumably head) motion. It includes a Philip Glass-worthy soundtrack of spikes from (I guess?) an electrode array.

On a related note, somebody has uploaded an old Hubel and Wiesel receptive field mapping recording from V1 on YouTube. If you haven’t seen it already, it’s gold.
