where: Bordeaux Neurocampus (France)
when: Wednesday 26 noon to Friday 28 noon
preceded by: minischool on spike sorting (Tuesday 25 - Wed.26).

#Tetrode recordings (in a bundle): did you know that you could record the same neuron on two different tetrodes?
or even three different tetrodes??

After checking that, turns out I usually have about 5-10% of neurons that are a duplicate of another neuron, in a given 8-tetrodes recording! They are pretty easy to detect with a firing rate correlation so I can remove them from analysis.
But I bet most neuron counts in published papers are inflated of that much!

Here's an example where you can see the spike plots and waveforms of 3 different, well-isolated clusters, recorded from 3 different tetrodes!

It's always nice when you finally finish #SpikeSorting an old recording session and find many #PlaceCells (here, 101) 🥰

I also recently implemented a way to remove putative duplicate recordings (when spikes from the same neutron are detected in two different tetrodes) and there can be a surprisingly high amount, 6-10 % of cells as far as I can see, this is with bundles of 8 tetrodes.

A bottle in the sea but has anyone here ever coded a plug-in for #Phy (the #SpikeSorting visualization software)? If yes I have questions for you, like… would you share your plug-in with me so I can see how you did it?
