We have a new preprint which characterizes characterizes two arteries that form the major blood supply to the hippocampus using in vivo Time-of-Flight (TOF) MR angiography 3T on 7T and . 🍤. We used compressed sensing to substantially reduce scan time and compare vessel diameter estimates and CNR.

We have a new preprint examining single neuron responses in humans undergoing TMS (www.biorxiv.org/content/10.6...). The excellent Charlie Dickey led the way, and I had the privilege to co-supervise this work with @coreykeller.bsky.social and @aaronboes.bsky.social 🧵 (1/7) 🧠🟦 🧠💻
Image showing the paradigm for recording single neurons in a variety of brain regions in humans, while single-pulse TMS was applied to dlPFC. One subpanel shows that single neurons were able to be resolved very early (8ms) after the single-pulse stimulation. Another subpanel shows two example neuron waveforms, along with their inter-spike interval distributions. The final subpanels show spike density functions overlaid on raster plots for the same neuron, separately for active and sham stimulation, in order to demonstrate that active (but not sham) stimulation increased activity in this example neuron.

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case. www.nature.com/articles/s41...

Deconstruction of a memory engram reveals distinct ensembles recruited at learning - Nature Neuroscience
Pouget et al. identified distinct CA1 neuron ensembles active during specific moments of fear learning and uncovered the core engram essential for memory formation.

Using brain lesions and DNN models, this article suggests that human visual perception is modulated by language.
nature.com
Combined evidence from artificial neural networks and human brain-lesion models reveals that language modulates vision in human perception - Nature Human Behaviour
Vision–language deep neural network models better explain human visual cortex activity than vision-only models. Damaging brain connections between visual and language areas reverses this pattern, suggesting that human visual perception is modulated by language.
