Fantastic collaboration with @jamespriestley4, @faffofratello, Luca Mazzucato, @StefanoFusi2 , @losonczyattila, & teammates at @ColumbiaPsych and @ZuckermanBrain! Our new paper on learning & memory is now out @NeuroCellPress!

[Columbia University's Zuckerman Institute @ZuckermanBrain]

NEW RESEARCH: A @ZuckermanBrain study in mice reveals how the brain builds bridges across time — by firing off bursts of activity that seem random, but in fact make up a complex pattern that, over time, helps the brain link events to form a memory. 👇🏻

[Mohsin Ahmed @mohsinmdphd]

Such a privilege to co-lead this work with @sebirolotti in amazing collab with Miki Szobozslay, @attila_losonczy, & others across @ZuckermanBrain & @ColumbiaPsych!

Check out how we scaled rapid plasticity to enhance subsequent learning @NeuroCellPress!

We looked at the role of prefrontal neurons in a rodent model of cross-sensory attention shifting, and get this...

Back-2-back 🏆 Focused mentoring, impactful research, and an inclusive enterprise are not mutually exclusive. In fact, THEY ARE SYNERGISTIC. The mentees gonna have a field day with this prize money. 🤦🏽‍♂️ What's the NC gathering limit these days? 🙄 ...Back to mentor training...

[Alexander Harris @dr_alexharris]

We have a ✨new ✨ paper out today... and its about novelty!

My paper is out @nature! Afraid of living in this era of uncertainty? No worries, your brain knows what to do. Facing novel situations resets brain circuitry, enabling rapid information updating and adaptation to novel situations. https://t.co/HRKmrCfqVM

[Carolyn Rodriguez @CRodriguezMDPhD]

New #hoarding disorder study led by Drs. Amanda Mahnke, Omer Linkovski and Kiara Timpano & @RodriguezLabSU team - @AndreaVarias @mfilippoufrye @petervanroessel @Brianna_JWright "Examining subjective sleep quality in adults with hoarding disorder" https://t.co/Q5Ou4c6Gg8

[Alex Kwan 關進晞 @kwanalexc]

A focused study from our lab to answer one question – what is the extent and time scale of effects of #psilocybin on dendritic architectures in vivo? Led by Lingxiao Shao with help from @ItsClaraLiao @NeilSavalia and others. @YalePsych @YaleNeuro 1/7

[Stefano Fusi @StefanoFusi2]

High dimensional representations for low dimensional tasks. A great collaboration with @RNogueiraNeuro, @chrisXrodgers and @TheBrunoCortex: The non-linear mixed representations in somatosensory cortex support simple and complex tasks https://t.co/WgNjIIv7Fa

[Pitt Psychiatry @PittPsychiatry]

In a recent @NatureComms study, scientists asked, When making decisions, how does one decide whether to exploit known good options or explore potentially better alternatives? The hippocampus plays a key role in resolving the explore/exploit dilemma: https://t.co/jSR2a7uNss

@dr_alexharris @ColumbiaPsych Congrats!!! Great news Alex!

[Brendon Watson @brendon_watson]

Our paper in Stress showing differential behavioral effects of ketamine depending on sex and stress status. Sex/stress differences are not straightforward! From @pfitz1940 with Savannah K. Kounelis-Wuillaume, Ali Gheidi, @jon_d_morrow and @JSpencerSegal: https://t.co/MAOq8qL3Lx

[Gaurav Patel @neurofreak]

Come join us at @DSCLab and @ColumbiaPsych! We are hiring a postdoc (https://t.co/Hq8FYkJuys) and a programmer (https://t.co/aJm6172WgG) to join our R01-funded projects on retinotopy, social cognition and schizophrenia!

[SPARED Center at McLean Hospital @AtSpared]

New work by SPARED’s own #Carlezon lab uses #DREADDs to show how #stress effects on nucleus accumbens are sufficient to dysregulate of #REM sleep, a key feature of depressive illness. 🧠https://t.co/vjPHf3N2RR

[Brendon Watson @brendon_watson]

New review article from my lab about the possible role of cholinesterase inhibitors (like Aricept) in treating depression or chronic stress. Led by @pfitz1940 @CommanderPho and Anjesh (Josh) Ghimire!. https://t.co/DvtAxlPAk6

[Mohsin Ahmed @mohsinmdphd]

@_DrOctothorpe_ Congrats!!!

[Mohsin Ahmed @mohsinmdphd]

Really awesome work led by Rick Warren from @TheBrunoCortex & Nate Sawtell labs at @ZuckermanBrain. Check it out!

[Randy Bruno @TheBrunoCortex]

Exciting new work from brilliant collaborators Rick Warren and Nate Sawtell (NoT) about a skilled motor behavior that doesn’t require cortex! Head-fixed, running mice jump over virtual “hurdles” of varying height, precisely shaping limb movements to match hurdle height. How? 1/n

[Nanthia Suthana @SuthanaLab]

🥳 New lab paper out today in @Nature 🥳

Deep 🧠 activity recorded in humans during🚶🏻‍♀️& when 👀ing @ another person🚶🏽‍♀️in a shared environment... exciting findings 👇

👏1st-author @MatStangl for the brilliant💡s & tireless hard work. #ProudPI

[Mohsin Ahmed @mohsinmdphd]

Terrific framework article from @kwanalexc & colleagues on the importance of dendritic microcircuit computations for exciting lines of therapeutics in psychiatry!

[Alex Kwan 關進晞 @kwanalexc]

Our new opinion article @TrendsNeuro, proposing that a key shared action of #ketamine and serotonergic #psychedelics is their ability to modify dendritic excitability in pyramidal neurons. https://t.co/JmMDTWsNqq 1/8

Congrats Fraser Sparks & @neurozhen on fantastic translational neuroscience work, shedding light on neurobiology of epilepsy - out now in @NatureComms!

[Zhenrui Liao @neurozhen]

Joint work with Fraser Sparks, now out in @NatureComms ! Using calcium imaging and Bayesian topic modeling, we show adult-born neurons pathologically couple to each other during interictal spikes in chronic temporal lobe epilepsy in mice

[Zachary Freyberg @zfreyberg]

Exciting new opportunity to put out your science in the emerging new world at the intersections of psychiatry, metabolism and neuroinflammation! Looking forward to this special issue!
