1/ Very happy to share that my main PhD paper is out in
@NeuroCellPress! We used simultaneous neural recordings in behaving rats to show that dorsal and ventral hippocampus talk to the nucleus accumbens about different things. Thread below for more. https://www.cell.com/neuron/fulltext/S0896-6273(19)31008-6 …pic.twitter.com/Y97zFqOj10

Fascinating! Inactivating the anterior thalamus disrupts place cells in the subiculum but not CA1, and impairs spatial alternation memoryhttps://twitter.com/biorxiv_neursci/status/1223978484889989120 …

This is insanely cool. Can you predict what’s happening in one brain from the brain of another individual? Apparently yes, yes you can.https://twitter.com/mattmizumi/status/1223426917027794945 …

Fantastic new work from Loren Frank's group: Uncovering the Neural Basis for Hypothetical Thinking in Ratshttp://bit.ly/3aY2Lvy

The hippocampus “holds in mind” future possibilities on alternating cycles of the theta rhythm— a potential mechanism of deliberation. Honored to have been a small part of this work, and stoked for the world to see Kenny’s elegant findings!https://www.cell.com/cell/fulltext/S0092-8674(20)30061-1?rss=yes …

Hey people! It’s online! I am SO delighted to share my latest and favourite piece of work: Courtship behaviour reveals temporal regularity is a critical social cue in mouse communication https://www.biorxiv.org/content/10.1101/2020.01.28.922773v1 …

And to think some would argue rat behavior isn’t relevant to humans

There is incredible power in retelling the pain of history. I’m grateful my grandparents were able to escape the Holocaust by coming to the US.

Excited to share my first postdoc paper that just came out today
@NeuroCellPress ! We looked at how the Locus Coeruleus modulates place fields around a rewarded location in CA1. The result of a fruitful collaboration with a graduate student!https://www.cell.com/neuron/fulltext/S0896-6273(19)31095-5#%20 …Thanks. Twitter will use this to make your timeline better. UndoUndo -

Nice work showing tight coordination between ripples and RSC spiking. Interestingly, RSC excitatory neurons fire before ripples only in sleep, and not in wake! (See supplemental)https://www.cell.com/cell-reports/fulltext/S2211-1247(19)31695-X …

Excited to share what
@jpillowtime@scott_linderman and I have been working on recently! We unify and generalize statistical models of neural dynamics during decision-making using switching state-space models https://arxiv.org/abs/2001.04571 pic.twitter.com/KKtSGPhKhN

Distributional reinforcement learning (RL) algorithms predict the entire ‘distribution’ of future rewards not just the average and improve the AI performance. This work presents evidence that the brain’s dopamine system uses distributional RL.https://www.nature.com/articles/s41586-019-1924-6 …

1. Submit = showing Simba to the kingdom 2. Reject = Mufasa dying 3. Reviewers = hyenas 4. We have friends to drink and sing and cry with 5. Resubmit = reclaim kingdom 6. REPEAT #2-5 a few times 7.

Turns out your brain’s speedometer and compass are actually quite flexible! Beautiful work. Congrats to

We are excited to release SimBA (Simple Behavioral Analysis)! SimBA is a GUI-driven open-source program that automates scoring of complex rodent social behavior under common video recording setups and with no specialized hardware.pic.twitter.com/UGGaV342ff

1/ Very proud that our paper is finally out in Nature Neuro! We use new wire-free miniaturized microscopes and electrophysiology to find interneuron desynchronization and long term place cell instability in a model of temporal lobe epilepsy.https://www.nature.com/articles/s41593-019-0559-0 …
