Mind the Gaps! A thread to tell you about our fresh Science Advances @science.org paper: www.science.org/doi/10.1126/...
Photomapping electrically coupled networks of the mature thalamus and cortex
Electrical synapses are expressed ubiquitously across the brain and are crucial components of active neural circuitry and connectomes. Identification of coupled networks in living tissue is limited by...

My friend was recently diagnosed with epilepsy. She wrote about her experience:
My lab just opened at Lehigh University - we study the origins, mechanisms, and impacts of the rapid evolution of the chromosome segregation machinery. I'm looking for 2 team members (postdoc and lab tech) who are passionate about evolution and cell division! See the opportunities at dudkalab.me.

I got offered millions, a lab, cutting-edge equipment, and any collaborator I wanted during Bush 2, all I had to do was develop low-frequency transmitters to go inside a soldier's helmet to affect brain activity. The plan was not to inform them. I noped out so hard, I make lotion now. But many 1/

I'm happy to share that the final version of our retinal electrical synapse proteome is out. We used proximity biotinylation techniques to capture proteins associated with Cx36 in mouse retina and Cx35.1 in zebrafish retina. elifesciences.org/articles/105...

Don’t forget gap junctional coupling. Everyone forgets gap junctional coupling, but it’s upwards of at least 25% of the current throughput in some retinal circuits.

Olivier George@brainaddiction.bsky.social · 7mo agoWhy does this matter beyond the lab? 15–25% of women experience menstrual irregularities, and those women show ~40% higher rates of mental health disorders, including substance use disorders. The causal direction is usually assumed to run one way: drugs disrupt hormones.
This first person history by John O'Keefe of the discovery of place cells is a must read. This whole special issue is full of gems. It's edited by my PhD advisor Michael Hasselmo. It's filled with first person accounts of famous discoveries. Fantastic idea. onlinelibrary.wiley.com/doi/10.1002/...

New paper from the Geffen and @labhaas.bsky.social Laboratories just published! We find that the enigmatic thalamic reticular nucleus exerts bi-directional cell-specific control over sound processing. The super-thin sheet of inhibitory neurons is rather mighty and highly computationally relevant!

Agree this is a very cool paper. The result is that soma-dendritic mismatch reflects an error (teaching) signal. Below panel (5e) is key data, supporting the idea that their SD residual approach captures differences in their two populations as a function of the behavioral outcome (error).

Yes. Important in the context of the release of the NIH budget bill today. NIH has been dismantled this year, and it’s NOT because of a Congressional budget cut. It’s b/c of Project 2025/Russell Vought reaching into NIH in an unprecedented way and screwing up how it’s run. The budget bill does…
Dr. Becca@docbecca.bsky.social · 9mo agoJust spoke to The Hill about how the dismantling of the NIH is impacting science in America. We still face a cliff of unfathomable heights, w easily 1000+ labs poised to close in the next year due to funding ending. A generation of young scientists lost because there is nowhere for them to train.
I've witnessed similar, at a science conference, evaluating the sex characteristics of a speaker in no uncertain terms. Text in large font, because age I assume, or maybe it was in fact meant for everyone to read after all. So dehumanizing. Still not sure what I should have done.

If this result generalises, then the field's great dendritic computation dream is over
@adamezracohen.bsky.social · 10mo agoSome things we learned: 1. CA1 pyramidal neuron dendritic voltage dynamics during behavior are low-dimensional, well described by just two or three compartments (basal, soma, apical). This rules out models in which dendritic branches act as distinct computational compartments.

We tend to think of neurons as either excitatory or inhibitory, but some neurons chemically inhibit their downstream targets while electrically exciting their neighbors. What is gained by having an inhibitory neuron excite its neighbor? www.biorxiv.org/content/10.6...
