Smartphone behavior is suppressed during bursts of wake slow wave

Real-world behavior unfolds as a continuous flow of actions over time. One possibility is that this continuous flow is enabled by a seamless stream of cortical activity. However, emerging evidence sug...

The search for the mechanisms cortical regulation of sleep continues. Latest collaborative work suggests that part of the answer lies in the cortex.
By switching cortical neurons on and off, we could change how much sleep animals got — and even the quality of that sleep. doi.org/10.1101/2025...

Bidirectional modulation of sleep and wakefulness via prefrontal cortical chemogenetics

The drive to sleep is inescapable but its biological substrate remains largely elusive. Until recently, the search for sleep centres in the mammalian brain focussed on subcortical neurons that promote...

in the spirit of the recent #psychedelic GRC which is heretofore known as the 'WOODSTOCK OF PSYCHEDELIC SCIENCE' I propose a new definition in which every psychedelic is 'classical'!!

Delighted to be part of the first Gordon Conference devoted to psychedelics #GRCPsychedlics. My message this morning: science is in this dark place now partly because we spend all of our time and effort in the lab. Get out and talk about your science with the public! Your science will benefit too!
