Exploring the Brain, One Neuron at a Time

A wearable ultrasound patch can coax your brain into deeper, restorative sleep without drugs or surgery. In a study of 28 people, the device slashed the time to REM sleep by 43 minutes while extending it by about 16 minutes and improving stress regulation.

A novel autism therapy that blocks a specific brain transporter restored critical neural signaling and reversed social and repetitive behaviors in adult mice—challenging the long-held belief that the autistic brain loses its ability to adapt in adulthood. The treatment also worked in human brain tissue samples, opening doors for potential adult therapies.

Around age 50, your brain's memory center undergoes a striking cellular swap, shedding protective immune cells in favor of inflammatory ones that may set the stage for Alzheimer's. This age-triggered transformation could explain why dementia risk climbs so sharply in later life.

A prescription form of THC made recurring PTSD nightmares vanish completely in more than one-third of patients within ten weeks—offering hope for one of trauma's most relentless symptoms. The finding suggests a long-awaited breakthrough for treating one of the disorder's most disabling features.
