brain stimulation

Low-intensity electrical stimulation allows older adults to better recall a list of words for at least a month following the treatment, a study finds, providing further evidence for the debated idea that electrical stimulation can enhance cognitive performance.

A study finds that injuries to certain areas of the brain were associated with quitting smoking more quickly, easily, and with no cravings.

Two out of three people who received noninvasive ultrasound appear to have gained some level of consciousness, according to preliminary trial results.

Strategies to make lab animals forget, remember, or experience false recollections probe how memory works, and may inspire treatments for neurological diseases.

Researchers have developed ways to manipulate neurons involved in a particular memory to make mice recall an experience or to remember something that never happened.

The effects of the therapy in a small group of  patients were long-lasting, researchers say, adding to evidence that the approach works for treatment-resistant depression.

The approach temporarily improved the performance of older adults on memory tasks to be on par with people in their 20s.

Despite previous positive reports, researchers didn’t see transcranial direct current stimulation (tDCS) cut back on people’s urges or eating.

Studies have demonstrated that magnetic and electrical currents can enhance memory in human subjects, but the technology is not yet ready for prime time.

Researchers have been using ultrasound to control brain activity, but studies in mice and guinea pigs show it also stimulates the auditory system, presenting a confounder for direct neural stimulation.

New techniques for activating or suppressing neural activity by zapping the skull’s surface allow researchers to target smaller and deeper areas of the brain.

In people with epilepsy, transcranial alternating current stimulation (tACS) does not affect memory-related brainwaves as widely claimed, researchers report.
