We had a look at a question I am really excited about: does an individuals intrinsic brain rhythm predict speech tracking and comprehension? And how do speech motor and auditory rhythms work together? by Christina Lubinus, @annekeitel.bsky.social @jonasobleser.bsky.social @davidpoeppel.bsky.social

Very excited to share our latest paper led by @nbinish.bsky.social in @natneuro.nature.com We demonstrate how a communication subspace channels higher-dimensional PFC dynamics into lower-D motor activity to enable efficient behavior using human iEEG. www.nature.com/articles/s41... #neuroskyence

A communication subspace relays context-dependent actions from human prefrontal to motor cortex - Nature Neuroscience
Context-dependent behavior selects actions according to task demands. Using direct brain recordings in humans, Binish et al. uncover how coordinated population activity efficiently channels informatio...

Two postdoc opportunities @yale.edu in human neurophysiology. One position in my lab @wutsaiyale.bsky.social focusing on human cognitive neurophysiology. Details at helfrich-lab.com/news/ Plus a possible collab with anesthesiology 👇 #NeuroTwitter #NeuroJobs #neuroskyence #EEG Please share.

Out now in @natcomms.nature.com, our latest from @bodybrainbehaviour.bsky.social: Visual perception, oscillatory excitability markers, and network connectivity are modulated by the breathing rhythm - depending on how much you know about the stimulus. #brainbody #neuroskyence

New preprint with amazing work from @nchalas.bsky.social: How does respiration influence (un-)predictable near-threshold perception? MEG, arousal modulation, excitability states, respiration phase-resolved connectivity changes - it's all there :) #neuroskyence www.biorxiv.org/content/10.1...

Respiration as a dynamic modulator of sensory sampling
Respiration dynamically modulates sensory perception by orchestrating transient states of the brain and the body. Using simultaneous recordings of high-density magneto-encephalography (MEG), respirati...
