#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!

Extracellular ephys peeps: Are you building your own microdrives/hyperdrives/implants? In their new preprint on http://bsrxiv.org, van Heument et al systematically analyze how many you should build to make them awesome!
