#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.

My 3 #Resolutions for the new year?
[1] Close my Twitter account
[2] Start a #BulletJournal to see if it increases my #Focus (and #Productivity)
[3] Get my #Hexamaze study published!

What about you all?
#NewYear2024

Very early sneak peek on what I'm currently working on... Yes it's #PlaceCell #Replay !!
