🚨 !!! New preprint !!! 🚨
Excited to share my student @samibeaumont’s latest work, where we demonstrate that inference over putative strategies is sufficient to fully accounts for human adaptation across diverse statistical contexts, when reinforcement learning cannot. 🧠🟦 🧠🤖

One hundred years of EEG for brain and behaviour research - Nature Human Behaviour On the centenary of the first human EEG recording, more than 500 experts reflect on the impact that this discovery has had on our understanding of the brain and behaviour. We document their priorities...

A must read paper in Nature Human Behavior for anyone in the fields of #EEG #neuroscience #neurology #psychology or #medicaldevice

Interested to know what people agree and disagree with? There are several things that they say are years away that are already happening

@hritz.bsky.social hi could you add me to the cog. Control sp. please ?
Thanks 🙏
We just showed with a student with intracranial human recordings that an optimal level of theta is required for task switching

That was fast !
😊

@guidomeijer.com hi, could you add me to the sp. On system neuro / neuronal population fans, please ?

Intracerebral mechanisms explaining the impact of incidental feedback on mood state and risky choice Invasive electrophysiological recordings from the human brain reveal that different mood levels translate into different brain states that predispose subjects to make risky or safe decisions.

Thanks for sharing this we also have several electrophysiology Al studies

Direct stimulation of anterior insula and ventromedial prefrontal cortex disrupts economic choices - Nature Communications Activity in the vmPFC and anterior insula is associated with economic choice and confidence, but their causal involvement is unclear. Here, the authors show that intracranial stimulation of subregions...

Lateral prefrontal theta oscillations causally drive a computational mechanism underlying conflict expectation and adaptation - Nature Communications Martínez-Molina et al. utilized fMRI, EEG-TMS, and cognitive modeling to reveal the mechanisms behind expectation and adaptation to upcoming conflicting events, demonstrating the causal role of theta ...

Happy 🎉 to share that our article 🚨, "Lateral Prefrontal Theta Oscillations Causally Drive a Computational Mechanism Underlying Conflict Expectation and Adaptation," has been published 📚 today in NatureComms. (1/8)

Neuronal sequences in population bursts encode information in human cortex - Nature The temporal order of neuronal firing within bursts of population spiking in the human anterior temporal lobe is dependent on the category as well as the identity of the individual stimulus, and this ...

Neurons in the human brain multitask! Shared neurons fire in bursts for multiple stimuli, but their firing order shifts to create stimulus-specific sequences. A clever, dynamic way the brain encodes complex info.

Hi can you add me to this sp.
Thanks for creating it 😊

Does brain activity cause consciousness? A thought experiment The authors of this Essay examine whether action potentials cause consciousness in a three-step thought experiment that assumes technology is advanced enough to fully manipulate our brains.

The craziest paper I have ever done is this thought experiment with Albert Gidon and Matt Larkum.

In the first journal, reviewer 1 recommended that we should not try to publish this; reviewer 2 called it "wacky". Thanks for the motivation: A sequel is coming up!

Four years of work: congrats to romane: well done !!

We are also looking for a PhD (36 to 48 months) to study single-neuron correlates of human decision-making processes .
