Immediate cortical glial alterations following spinal cord injury: Evidence from a novel in vitro model Spinal cord injury (SCI) triggers immediate and widespread pathophysiological changes not only at the site of impact but also beyond it, including alterations in remote cortical regions. Here, we rep....

Did you know that spinal cord injury can induce a remote effect on the cerebral cortex?

I did not. There are very few studies about that!
 
📣 Check out our brief communication on how spinal cord injury can impact the density of cortical #astrocytes 😮

After years of wondering, I finally vibe-coded my blog!

🧠Neuroscience has long told a neuron-centered story, but maybe that’s only half the picture. #Astrocytes, the so-called housekeepers, may hold some hidden insights.

A functional perspective on astrocyte heterogeneity Astrocytes are glial cells of the central nervous system (CNS) that perform an array of diverse functions that are essential for brain activity. Studies on the functional diversity of astrocytes sugge...

A functional perspective on astrocyte heterogeneity

Maybe top-down signals, as current context, provide positive feedback instead of prediction errors, just up-modulating the bottom-up pathways associated with the current context in past experiences. The pathways out of this +modulation receive negative feedback, but not enough to entirely block them

The oneirogen hypothesis: modeling the hallucinatory effects of classical psychedelics in terms of replay-dependent plasticity mechanisms Classical psychedelics induce complex visual hallucinations in humans, generating percepts that are coherent at a low level, but which have surreal, dream-like qualities at a high level. While there a...

1. Hi all: I’m here to advertise our new preprint: www.biorxiv.org/content/10.1..., with Fabrice Normandin, @tyrellturing.bsky.social, and @glajoie.bsky.social!

Welcome @neuralreckoning.bsky.social!
Tagging for #neuroscience feed! 👇

do u know of someone who may be interested in starting a lab as a junior PI in Korea, to work on perceptual decision-making in mice? besides postdocs, we would consider someone fresh out of grad school too, or someone who wants to be a staff scientist for the longer term. 1/

hello friends in Japan (& elsewhere), there is a free conference on perceptual metacognition on July 1st in Tokyo. abstract submission deadline in two weeks.

one downside is that i'll be speaking there. but the other speakers are gonna be great

First post on here! Sharing a paper that I wrote with some friends on our thoughts on the role of astrocytes in the brain. We put forward the idea that astrocytes provide context to neurons and that this is one of their primary functions in the brain! Let us know what you think!

It took a minute, but we FINALLY have a lab website! 🎉

We are looking for graduate students and postdocs to join the team to study sleep😴 & astrocytes⭐️.

Is machine consciousness just around the corner?

In our new paper, we approach this question from the neuroscientific perspective and explain why this is unlikely to be the case

Hippocampal neurons code individual episodic memories in humans - Nature Human Behaviour Kolibius et al. show that individual neurons in the human hippocampus code for particular episodic memories.

Hippocampal neurons code individual episodic memories in humans.

The neurons don't code for a particular element in the episode (e.g., concept or time). They code for the conjunction of the different elements.

A Biophysical Model of Visual Rivalry Links Cellular Mechanisms to Signatures of Conscious Perceptio... bioRxiv - the preprint server for biology, operated by Cold Spring Harbor Laboratory, a research and educational institution

In lieu of an introductory post, I want to re-share our latest preprint which leverages a novel thalamocortical spiking neural network to bridge the gap between the cellular mechanisms of perception studied in rodents and the behavioural signatures of conscious perception studied in cog neuro.
