Lab’s latest is out in Imaging Neuroscience, led by Kirsten Peterson: β€œRegularized partial correlation provides reliable functional connectivity estimates while correcting for widespread confounding”, where we demonstrate a major improvement to standard fMRI functional connectivity (correlation) 1/n

Of potential interest to those keen on motor control and/or multi-task networks. Congrats to Elom and Eric.

Rate and noise in human amygdala drive increased exploration in aversive learning - Nature Human exploration is driven by two distinct neural mechanisms, a valence-independent rate signal and a valence-dependent global noise signal.

This is an exquisite demonstration of using intracranial recordings in humans to validate our findings that amygdala neurons encode the value of exploring in NHPs.

What do representations tell us about a system? Image of a mouse with a scope showing a vector of activity patterns, and a neural network with a vector of unit activity patterns
Common analyses of neural representations: Encoding models (relating activity to task features) drawing of an arrow from a trace saying [on_____on____] to a neuron and spike train. Comparing models via neural predictivity: comparing two neural networks by their R^2 to mouse brain activity. RSA: assessing brain-brain or model-brain correspondence using representational dissimilarity matrices

In neuroscience, we often try to understand systems by analyzing their representations β€” using tools like regression or RSA. But are these analyses biased towards discovering a subset of what a system represents? If you're interested in this question, check out our new commentary! Thread:

The butterfly-like/four circular labeling in the mediodorsal (top two) and submedius (bottom two) thalamic nuclei when retrograde tracers are infused in the medial prefrontal cortex (mPFC) of rats

"people use it very differently".. this applies to so many concepts in neuroscience!
We (@irinapochinok.bsky.social and Simon Musall) put together a #BernsteinConference Workshop on exactly this and @juangallego.bsky.social will be one of our speakers!

Very excited about this work and very proud of @xiongbowu.bsky.social who did it all:

Based on 4 independent data sets (incl. EEG/iEEG, eye tracking, gaze manipulation & memory), we advocate for a new perspective on the function of the brain's dominant rhythm 🧠

A hypothalamic circuit that modulates feeding and parenting behaviours - Nature Single-cell transcriptomic analysis of mouse hypothalamus and behavioural experiments show that specific hypothalamic networks regulate conflicting feeding versus parenting behaviours of female mice.

How do animals decide if they should forage for food or stay home to take care of newborn offspring? Whose needs come first? For my PhD work now out in Nature, we examined how hunger and parenting neurons interact and are reshaped postpartum in mice πŸ§΅β¬‡οΈ www.nature.com/articles/s41...
