How does the brain replay memories during sleep?
Excited to share our new preprint, the outcome of an extensive effort led by Johannes Niediek, showing that reactivation of human concept neurons reflects memory content rather than event sequence.

VTA dopaminergic neuronal activity during NREM sleep is modulated by learning and facilitates motor memory consolidation Activity of VTA dopaminergic neurons during NREM sleep facilitates motor memory consolidation and is coordinated with spindles.

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?

Ok, not *that* kind of mind reading, but we have created a deep learning method capable of using single neuron recordings from people watching episodes of TV that can predict when they recall specific memories from the episode. 1/6
