%%% Achilles151_11042013 %%% In summary: There is a disturbance in the neural data around second 13503, which is right when behavior began. Sigh. Only do pre-behavior, post- analysis with caution. -(2/27/2014) Something is wrong with the clu file associated with shank16, one of the VTA tetrodes. I excluded it from the analysis. left-hemisphere swr: Channels 20-29 (base 0) left-hemisphere theta: Channels 21 (base 0) This one is in the pyramidal cell layer, so go with it right-hemisphere swr: right-hemisphere theta: EMG channel: 145 (base 0) Neural Data: -shank01: this shank turned out to only be OK. Some frustrating noise. -good cells 01006 : p 01008 : p 01009 : p 01011 : p 01012 : p, fires unreliably around one reward -shank02: A pretty good shank. Not a lot noise blurring the boundary between units. -good cells 02006 : p 02007 : p, nice place field around 1 reward 02008 : p 02009 : i -shank03: pretty good one -good cells 03003 : p 03004 : p, place field at second reward and near home port 03006 : p 03007 : p 03008 : i 03009 : p 03011 : i 03012 : p, a place field around one reward. Though, a little unreliable 03013 : p, a scattered place field between 4 and 6 o'clock 03014 : p -shank04: this shank turned out to be just OK. It was difficult to deconvolve the units. -good cells 04004 : p 04005 : p, a very compact field between 2 rewards 04006 : p, doesn't fire during the task. It does in the home port, though. 04007 : p, doesn't fire during the task. It does in the home port, though. 04008 : p, large and diffuse place field -shank05: several good cells, initially fragmented over many clusters. A huge interneuron. -good cells 05002 : p, no firing on platform 05004 : p, compact place field at 12 o'clock. Looking around? 05007 : p 05008 : p, on one trial this unit fires a lot at one reward location 05009 : i, amazing interneuron, decreases firing around reward location? 05010 : p 05011 : p, a place field mainly around one reward. Scattered firing elsewhere... 05013 : p 05015 : p 05018 : p, place cell with 2 non-overlapping fields (USE AS REFERENCE FOR INTER-TRIAL SWITCHING) -shank06: lots of interneurons -good cells 06002 : i, decrease in firing rate around reward locations 06003 : p, a place field with a lot of scattered firing around 06004 : i, decrease in firing rate around reward locations 06005 : i 06006 : i, decrease in firing rate around reward locations 06007 : i, decrease in firing rate around reward locations 06008 : p [nice high fr pyramidal] 06009 : p, one large place field -shank07: the extra 4 channels on shank 4(?). A bunch of garbage. -shank08: not a lot of cells here -good cells 08003 : p 08004 : i, decrease in firing rate around reward locations 08005 : i, decrease in firing rate around reward locations -shank09: this shank has some very nice units. Their waveforms are so big that there is a little variance. -good cells 09002 : i, decrease in firing rate around reward locations 09003 : p 09005 : p, firing rate decreases over the last 5 trials 09006 : p, a compact place field emerges around one reward location on trial 6 09007 : p, place field emerges along exit route. Route specific? Head direction 09008 : i, [this unit and 09010 might be the same, despite my attempts to separate them] 09009 : p, a large, diffuse field in the center of the platform. Decreasing firing rate across session 09010 : p, Decreasing firing rate across session 09011 : p, a large, diffuse field in the center of the platform. 09012 : p, place field in the center of the platform -shank10: this shank turns out to be pretty noisy -good cells 10003 : p, place cell with multiple fields. One along the right emerged on Trial 8. 10007 : p, small place field in upper left quad 10008 : i, decrease in firing rate around reward locations 10009 : p, vertical head direction cell? Scattered place field. -shank11: This shank turned out to be a bit of a mess. Just too many cells to sort out and a bit of mechanical instability. -good cells 11003 : p 11005 : i, decrease in firing rate around reward locations 11006 : p 11007 : p, large place field in the middle of the platform, elongated toward the exit 11008 : p, small place fields at 3 and 9 o'clock. Unreliable across trials 11009 : p 11012 : p, a place field with multiple, intermittent fields 11013 : p 11015 : p 11017 : p 11018 : p -shank12: this shank turned out to have a bit of mechanical instability. There are some good cells, though. They just wander around over the course of the recording. -good cells 12002 : i, decrease in firing rate around reward locations 12003 : i [lost at ~75% into the recording], decrease in firing rate around reward locations 12004 : i, decrease in firing rate around reward locations 12005 : p, place field emerge around 2 rewards nearest home port 12006 : p [lost at ~75% into the recording] 12008 : p 12009 : p, vertical head direction field, intermittent firing fields around one reward, lots of firing on trial 33 aas the animal ran forward with it's head up -shank13: a few cell + noise units -good cells 13002 : i, decrease in firing rate around reward locations 13003 : i 13004 : i 13005 : p, intermittent firing emerges around reward locations -shank14: a bunch of noise -shank15: VTA, interesting ISI distributions -good cells 15002 : ? 15003 : ? 15004 : ? 15005 : ? 15006 : ? 15007 : ? -shank16: VTA, problem with this clu file -shank17: VTA, a few nice units -good cells 17002 : ? 17003 : ? -shank18: VTA, -good cells 18002 : ? 18003 : ? 18004 : ? 18005 : ?
