Slow waves during sleep are fundamental for neural homeostasis and are impaired in neurodegenerative diseases. But what about sleep-like slow waves during wakefulness? Are these slow waves altered in Parkinson's disease? Are these slow waves uncovering psychosis?
Sleep-like slow waves during wakefulness uncover a malignant form of Parkinson’s disease
Slow waves during sleep are fundamental for neural homeostasis, metabolic regulation, and waste clearance, and are known to be altered in neurodegenerative diseases. Sleep-like slow waves (SLSW) have ...

🤔How does the human brain predict unexpected sounds?
Our new study shows that the prefrontal cortex doesn’t work as a single unit. Instead, the orbitofrontal and lateral prefrontal cortex make distinct, time-sensitive contributions. #iEEG #BrainLesion #OFC #LPFC

Predictive encoding of auditory sequences in the human prefrontal cortex
Humans extract regularities from the environment to form expectations that guide perception and optimize behavior. Although the prefrontal cortex (PFC) is central to this process, the relative contrib...

Have a look at @neuromorphicboki.bsky.social tour de force: leveraging dynamical independence on #EEG to quantify *and* describe emergent dynamics under different anaesthetics!

For #consciousness, less can be more: conscious states show lower emergence but more structured emergent dynamics.

I am incredibly excited to announce that we have published our paper on how "Dynamical independence reveals anaesthetic specific fragmentation of emergent structure in neural dynamics"

Dynamical independence reveals anaesthetic specific fragmentation of emergent structure in neural dynamics
Conscious experience depends on the coordinated activity of neural processes that span multiple scales--from synapses to whole-brain dynamics. A recently introduced measure, dynamical independence, id...

🧠 Paper out!

We investigated how hippocampal and cortical ripples support memory during movie watching. We found that:

🎬 Hippocampal ripples mark event boundaries
🧩 Cortical ripples predict later recall

Ripples may help transform real-life experiences into lasting memories!

Movie-watching evokes ripple-like activity within events and at event boundaries
Nature Communications - The neural processes involved in memory formation for realistic experiences remain poorly understood. Here, the authors found that ripple-like activity in the human...
