Humor me: I’m reactivating the latest preprint from the lab (itza “new” trace) 🤓

Multi-Neuromodulatory fingerprints of an adaptive cognitive state: Cognitive engagement was predicted by joint GABA & ACh/Choline in PFC; by Dopamine & Cholinergic changes in striatum. Glutamate & ACh correlated across states. Kudos to team Dr Pawliszyn biorxiv.org/content/10.64898…

2/2 Abilities of inhibitory control, WM updating, and shifting distinguished cognitive phenotypes in NHP's; expl. factor analysis suggested 1) WM updating 2) Shifting/Learning, and 3 4) inhibitory control of interference from external vs internal sources are 4 sep. cogn. factors.

🌟 Cai Lab @Nature paper alert! In new work led by @mysteriousjoe_, we find that rest periods after learning not only stabilize new memories BUT ALSO integrate new memories with older ones from days past! (1/9)

I am and have been fascinated with how memories are formed and stored. A big challenge, not unique to memory, is synthesizing concepts across scales of anaylsis - from molecules to computation. Here I try to distill how we can move forward in understanding memories. Thanks /1

Come to U10 U11 this morning if you’re interested in NHP cell assemblies, memory replay, wireless recording 100s of units during learning of new and old context-specific sequences, all in freely moving (and sleeping) monkeys #sfn2024

New research from @perpl_lab sheds light on the circuit organization that supports memory and spatial cognition. 🧠 This discovery helps with our understanding of how our brains process complex cognitive tasks.

Beautiful. We need more of this! Also newer Kilosort v’s created some issues as it solved others- @SAbbaspoor applied a system of manual curation after KS here; cell.com/cell-reports/fullte…

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. biorxiv.org/content/10.1101/…

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. hubs.ly/Q02H7G2d0 #DBCInside

Our MEG/MRI study from @TheCHBH points to subcortical regions involved in alpha modulation: If your left compared to right globus pallidus or caudate are larger, you can better modulate left than right hemisphere alpha power.
