A Nature study finds that star-shaped brain cells called astrocytes encode, maintain, and regulate fear memories alongside neurons, opening new paths for PTSD treatment.

The FDA granted Breakthrough Device Designation to Nia Therapeutics' 60-channel Smart Neurostimulation System, a closed-loop brain implant that uses machine learning to detect impaired memory encoding and deliver targeted stimulation, marking the first such designation for TBI-related memory loss.

A brain-computer interface developed by Mass General Brigham and Brown University decoded intended finger movements into QWERTY keystrokes at 110 characters per minute with a 1.6 percent word error rate, offering a faster alternative to eye-gaze systems for people with ALS and spinal cord injuries.

A Japanese research team has identified a small molecule called Mic-628 that advances the mammalian circadian clock by activating the Period1 gene through a previously unexploited molecular pathway, cutting simulated jet lag recovery from seven days to four in mice after a single oral dose.

China's NMPA approves the world's first commercial brain implant while a BrainGate study demonstrates 110-character-per-minute typing, marking a pivotal week for neural interface technology.

Takeda's oveporexton, an oral drug that restores the brain chemical missing in narcolepsy type 1, has received FDA priority review after two Phase 3 trials showed it brought patients to near-normal wakefulness and cut cataplexy episodes by more than 80 percent.

A Washington University team showed a p-tau217 blood test can estimate Alzheimer's symptom onset within 3-4 years, potentially transforming early intervention and clinical trials.

An 863-person Nature study identifies the SCAN brain network as the core driver of Parkinson's, with all four major treatments working by reducing its abnormal hyperconnectivity.
