3/3 c) Pay attention to spike sorter versions! Critics deemed our data "low quality" b/c neuron yields were lower than other studies. We dug deep. Turns out difference was due to use of different spike sorting versions. 🤯Paper now submitted to @eLife.

This is the first large-animal paper using all DBC deep array probes, but won’t be the last. If you’re into high density sampling (eg #neuropixels, scrolls, etc), and are considering good options for deep/indwelling/wireless/linear recordings, feel free to reach out!.
Cell Press published the research from @perpl_lab where Sam Abbaspoor and Kari Hoffman utilized the DBC Deep Array to uncover the macaque hippocampus's unique circuit dynamics govern navigation, memory, and social behaviors across species. #DBCInside
