NIH Study Reveals Astrocytes Actively Shape Fear Memory in the Amygdala, Challenging Decades of Neuron-Centric Models
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.
BrainGate Implant Lets Two Paralyzed People Type at 22 Words per Minute Using Attempted Finger Movements
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.
Brain-Computer Interfaces Enter the Commercial Era as China Grants First Approval and BrainGate Achieves Near-Able-Bodied Typing Speeds
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.
Blood Test Can Forecast When Alzheimer's Symptoms Will Begin, Study in Nature Medicine Finds
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.
Scientists Pinpoint the Brain Network Behind Parkinson's Disease and Show All Major Therapies Converge on It
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.
