Single Cell Recordings in the Fly Brain: Motion Adaptation Pt. 2

This video was made for a Philosophy of Neuroscience seminar based on research done in electrophysiology in fly brains. The topic was data collection and interpretation, but this video shows how one prepares and searches for a motion-sensitive neuron.

I'm aware of the grammatical mistakes in the film.

Buddy...your research rocks. I love to see classical, old school electrophysiology on action. Two questions and one remark...question..the H1 have also vertical directionality to the movement?....it's conceivable to make intracellular records on those cells with sharp electrodes?....the remark.....on the final paragraph of your video..you call those signals "action potentials"..they're not..those are spikes. Keep your fine work...it's very nice!.

Thanks for the comment. To your question, H1 and other cells in the lobula plate are both gigantic and located on the outer layers of the nervous system, so they are very accessible with the glass electrodes we use.

Secondly, it's said that H1 fires 'only' in response to horizontal motion (hence "H"), but it's also been established that it fires to patterns with various orientations (i.e. diagonal motion), though the spike frequency in the response shrinks as the pattern becomes more vertical.

Too complicated for me but if you got some techno skills I give a 10 on effort and another 10 because this is amazing!
