Let’s teach neuroscientists how to be thoughtful and fair reviewers Blanco-Suárez revamped the traditional journal club by developing a course in which students peer review preprints alongside the published papers that evolved from them.

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.

AI is rapidly changing how we write code — but how should we use it in research?

The boys’ club: How Epstein’s influence shaped the exclusion of women in STEM In one email, an AI researcher suggested it’s “hard to be brilliant if you are worrying if you look fat or why another woman hates you.”

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.

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:

Astrocytes enable amygdala neural representations supporting memory - Nature Astrocytes in the basolateral amygdala dynamically track fear state and support fear memory retrieval 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!🥳

‘Part of our biological toolkit’: newborn babies can anticipate rhythm in music, researchers find Brain activity suggests newborns can detect and predict patterns relating to rhythm, study says Newborn babies can anticipate rhythm in pieces of music, researchers have discovered, offering insights into a fundamental human trait. Babies in the womb begin to respond to music by about eight or nine months, as shown by changes in their heart rate and body movements, said Dr Roberta Bianco, the first author of the research who is based at the Italian Institute of Technology in Rome.

‘Part of our biological toolkit’: newborn babies can anticipate rhythm in music, researchers find

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).

A Common Iba1 Antibody Labels Vasopressin Neurons in Mice There are a wide variety of commercially available antibodies for labeling microglial cells based on different protein targets, as well as antibodies for the same protein target made in different spec...

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! 🔬

Europe loves to lecture the world about values, but morals without power is just vibes. We regulate AI we don’t build, sell handbags instead of hardware, and rely on others for our security and energy.

If we really believe in liberal democracy, we’d better be willing to back it up.

Ultrafast Frame-Free Imaging of Neural Activity with Event Cameras Frame-based fluorescence imaging has long defined how neural activity is optically measured. This approach requires acquiring all pixels within an image, regardless of whether they carry meaningful ne...

For decades, imaging has forced the same trade-off:
Set a frame rate → sacrifice resolution or field of view to go fast.

We break that rule

Using an EVENT-BASED CAMERA, we record neural activity without frames. Signals are captured only where and when they occur:
