Brain-controlled hearing aid concept helps solve the cocktail party problem

Researchers developed a real-time brain-controlled hearing system that uses neural signals to identify and amplify the speaker a listener is focusing on in noisy, multi-talker environments. Using intracranial brain recordings, the system improved speech intelligibility, reduced listening effort, tracked attention shifts, and provided a benchmark for future brain-guided hearing aids.

Researchers discover a brain signal that predicts child attention lapses

Inside a world-leading deep brain stimulation program at The Hospital for Sick Children (SickKids), researchers have discovered a brain signal that predicts when a child is about to lose attention - and that a brief, targeted intervention in response to that signal can restore their focus.

Single psilocybin dose linked to lasting brain and mood changes

Researchers at UC San Francisco and Imperial College London have shown that a single dose of psilocybin, the psychedelic compound found in magic mushrooms, causes likely anatomical brain changes that last for up to a month after the experience.

Sleep and age shape EEG brain signals during wakefulness

Clinicians use electroencephalography (EEG) to assess brain activity in epilepsy and sleep pathologies, and this powerful tool has shown promise for other conditions.

Brain-Gut Health Initiative supports AI-assisted diagnosis of psychiatric disorders

Psychiatric disorders affect millions worldwide, but their diagnosis still relies on clinical observation instead of standard biological tests.

Sleep brain activity offers clues to infant neurological development

Electrical signals from the brain could help identify potential issues in the organ's development, a new study reports.

Novel embedding-driven AI for adaptable brain control

Motor imagery (MI) is the mental process of imagining a specific limb movement, such as raising a hand or walking, without physically performing it. These imagined movements generate distinct patterns of brain activity that can be recorded using electroencephalography (EEG).

Exercise triggers memory-related brain waves in the hippocampus

A single session of physical exercise can spawn a boost of neural activity in brain networks that underlie learning and memory, according to a new study led by the University of Iowa.

Open-source Epicurrents library brings clinical neurophysiology recordings to web browsers

Clinical neurophysiology examinations include electroencephalography, sleep and vigilance studies, as well as nerve conduction recordings.

Sleep loss triggers brain fluid pulses that impair attention, study finds

Sleep deprivation causes attentional lapses that coincide with coordinated changes in brain activity, pupil diameter, blood flow, and cerebrospinal fluid dynamics. These findings suggest attention failures reflect a transient brain–body state linked to sleep pressure rather than isolated neural errors.

Natural movement timing enhances ownership of robotic arms

When AI powered prosthetic arms that move autonomously become widespread, understanding how people feel about them and accept them will be crucial.

Study identifies brain region driving one-shot visual learning

Despite decades of research, the mechanisms behind fast flashes of insight that change how a person perceives their world, termed "one-shot learning," have remained unknown.

EEG technology could be a useful tool for connecting brain signals with limb movements

People with from spinal cord injuries often lose some or all their limb function. In most patients, the nerves in their limbs work fine, and the neurons in their brain are still operational, but the damage to their spinal cords prevents the two areas from communicating.

Study sheds new light on how structural brain changes are tied to memory decline in aging

A landmark international study that pooled brain scans and memory tests from thousands of adults has shed new light on how structural brain changes are tied to memory decline as people age.

Struggling to make ends meet may slow brain development in infants

Researchers identify specific psychosocial factors that strongly correlate with altered brain development within the first year of life.

AI model can predict a person's disease risk using sleep data

A poor night's sleep portends a bleary-eyed next day, but it could also hint at diseases that will strike years down the road.

Income sufficiency emerges as key factor in early brain development

Decades of research show that early psychosocial stress, including chronic exposure to adversity, can shape how a child's brain develops, with effects that last well beyond childhood. But families rarely experience just one source of stress at a time.
