New review paper out today in @NatureNeuro with @DrBreaky, @eli_j_muller, @DrBMunn, @rosalynjmoran and @Joana_Cabral__, based on a symposium that we hosted at @OHBM in 2019 on the importance of the neuromodulatory arousal system for shaping whole brain dynamics (1/n)

I’m excited to share a new paper from the lab. The study led by Xiaowei Gu reveals how the mPFC encodes complex emotional memories, using an internal model to infer emotional associations and memories via projections to the amygdala

Do you have a plan for management of freezing of gait (FOG) in Parkinson's? I think about 5 things when constructing a PLAN. Check out the new paper by Tosserams, Fasano, Bloem, Nonnekes and colleagues in Nature Reviews Neurology.
Key Points:
- Freezing of gait is one of the most disabling symptoms in Parkinson’s.
- It is one of the most frustrating for patients and caregivers alike.
- People may describe it as feeling like their feet are glued to the floor, and FOG increases fall risk, anxiety, and loss of independence.
My Take: I urge our community to take a step forward with more coordinated plans for FOG in Parkinson's. FOG in Parkinson’s: Why do we need a plan? This paper offers us a clear, comprehensive, pathophysiology-driven framework to build a person specific plan. An important point that resonates for me: FOG isn’t one thing, it’s many things. It demands listening, with a personalized, evolving approach. It must addresses motor and non-motor factors that may underpin the manifestation.
Here are 5 key things I consider when treating freezing of gait (FOG):
1- Classify the type of FOG – Is it OFF-state, pseudo-ON, or dopamine-unresponsive? Your treatment will hinge on this.
2- Optimize dopamine – Tailor medications carefully, and consider infusion or DBS if or when appropriate.
3- Use non-drug strategies – Physical therapy, cueing, and gait training. These can be powerful, especially early in disease.
4- Treat the whole person. Anxiety, cognition, and sleep all interact with FOG. Addressing these features matters.
5- Think prevention: Exercise, balance training, and early identification. Can we delay FOG or treat the person more effectively so it does not emerge? Listen and optimize plans at every visit even if FOG is not present.
Let’s turn these insights into action. BRAVO to the authors. Don't be nolens volens – willy-nilly about freezing of gait (FOG).

@PiantadosiSean @mbruchas @Nature @aluskin @dilithium21 Thanks for tagging the team that did the beautiful work!

[Mac Shine @jmacshine]

I recently had the great pleasure of interviewing Michael Bruchas about an absolutely banger recent paper from his group that tracked down cells in the brainstem that subtlety and precisely control the output of the locus coeruleus. Check out my interview here!

[The Transmitter @_TheTransmitter]

Far from being a passive neighbor to the locus coeruleus, the pericoeruleus appears to act as a kind of micromanager of arousal, selectively inhibiting different subgroups of locus coeruleus neurons, writes Mac Shine.

Please chk out the lab's newest paper, a labor of love it was. From @aluskin & @dilithium21, w/ @madisonmartin @Braininajarr @mouse_braind @GoldenNeuron @gstuber & others. We report a new road map for the LC-NE & peri-LC systems. Thx @NIMHgov @NIDAnews https://t.co/foQXjqJwon

[Andrew Luskin @aluskin]

New paper on arousal in the brain! What controls the controller?

[Garret Stuber @gstuber]

Big congrats to @aluskin @mbruchas et al., on their paper on circuits controlling LC neurons. Lots of interesting data on the peri-LC cell types, connectivity, and function to dig into here.

We pay people to quit their jobs, and start fighting the world’s biggest problems instead.

Not someday. Not later. Now’s the time.

Already, 20+ people across Europe have made the leap.
Because the truth is: The world doesn’t just need more brilliant minds. It needs brilliant minds on the right side of history.

📢 EU Fellowship applications close May 12th.
🌎 Global (including U.S.) applications are now open and close soon.

Basal ganglia output is a formidable bottleneck

Striatum neurons project to output nuclei in a ratio ~16:1; but their targets outnumber them by up to 150 to 1.

New paper on how I got to those numbers & the model of basal ganglia output they imply
