Wait… localized norepinephrine transients in the awake visual cortex?!
Who would have guessed this neuromodulatory signal is that spatially precise, right where visual processing is happening. Brain state control just got a lot more local. @ruedigersarah.bsky.social www.nature.com/articles/s41...

Excited to share a new paper from our lab, just in time for Easter, where we characterize how arousal modulates different excitatory cell-types in the auditory cortex! www.science.org/doi/10.1126/...
@thetransmitter.bsky.social is doing a lot of the heavy lifting these days, bringing attention to how astrocytes shape behaviour. Here's a nice list of their recent reports -
The earth is heating far faster than was known and is beyond any type of intervention. Good luck
Fellow humans, we are way past climate change, the satellite watching nerds snapped this yesterday and the consensus is.
Holy shit lookout.
The entire Earth is heating up faster than thought, and past any human intervention.
This #FluorescenceFriday post is for those who do 2-photon calcium imaging. Make your videos pop! @filip-tomaska.bsky.social released code and a demo to make the neural activity in your videos clear.

Want to study visual maps in the mouse brain?
Our protocol shows how to:
• target visual cortex and superior colliculus
• perform intrinsic optical imaging
• use periodic stimulation to reduce acquisition time
• reveal retinotopic and orientation maps
• map ocular dominance

In the first essay of our new neuro-education series, @eblancosuarez.bsky.social shares how she reimagined the traditional journal club course by developing a class in which students review preprints alongside the published papers that evolved from them.

I wrote about the Epstein files and what they tell us about men in academia.
In a field where climbing the career ladder is only possible through a combination of luck, mentorship and networking — the files show the ways sexism and misogyny still hold women back.

The most sensitive green and red #norepinephrine #sensors engineered to date are out in #naturemethods! Deeply grateful to all our funders and contributors who made this work possible. A true team effort. @erc.europa.eu @snsf.ch doi.org/10.1038/s415...
Registrations and abstract submissions for #AstrocyteCafe2026 are now OPEN!!!

A cubic millimetre of the human brain. The whole thing is about 960,000 times this size, giving you some idea of the mind-boggling complexity we have yet to encounter. But you have to start somewhere.
Deadline approaching to apply for a PhD position in Exeter 🧠. 👇 Are you interested in cell-type diversity, glia and neudevelopmental disorders?
Triggering action potentials of a single neuron by multiphoton excitation elicits visually guided behavior
"disruption of a single neuron within the ensemble temporarily paralyzes the entire ensemble and suspends behavioral responses to visual stimuli"

We had a lot of fun doing these experiments! Theta sweeps in MEC and internal direction signals in parasubiculum track moving objects during pursuit and reverse during backward movement. Simultaneously recorded HD cells in other areas remain locked to head direction across behaviors:
Really nice work from the Holmes lab looking at amygdala astrocytes in fear memory and extinction!

New paper alert! 🚨
We found that the brain's compass is remarkably stable at two scales
1️⃣ the system maintains its internal organization for weeks
2️⃣ It "remembers" its orientation for weeks, even after a single visit
This may be key to how the brain aligns its other maps.

Super interesting work! Congratulations!🥳
Top left: Experimental paradigm. The authors analyzed EEG data recorded from 49 sleeping human newborns while being exposed to monophonic piano melodies composed by J. S. Bach (real condition) and control stimuli (shuffled condition). Top right: Surprise and entropy. Surprise and entropy associated with each note’s timing (green, St and Et, respectively) and pitch (yellow, Sp and Ep, respectively) were estimated using an unsupervised statistical learning model trained on all stimuli. Dot plots display mean surprise and entropy associated with real and shuffled music, averaged across melodies (left panel), and separately for each melody (right panel). Bottom: Analytical approach. Multivariate Temporal Response Function (mTRF) models were fit to describe the forward relationship between multiple stimulus features and the EEG signal. The full TRF model (leftmost panel) included acoustic low-level features (spectral flux, acoustic onset, IOI, and IPI) and high-level features (surprise and entropy of pitch and timing).
Does our very human ability to anticipate #musical structure exist at birth? @robertabianco.bsky.social @giacomonovembre.bsky.social &co show that #newborns encode #rhythmic (but not melodic) expectations based on statistical regularities in real #music @plosbiology.org plos.io/4kqKVWg
PSA for all #microglia lovers: certain Iba1 antibodies (see our new paper below for details) label not only microglia, but also vasopressin neurons, at least in mice. Brain region and species matter. A friendly reminder to always validate your antibodies! 🔬
