Correct connections are crucial

Investigators have been examining the use of deep brain stimulation in the treatment of Parkinson’s disease in an attempt to optimize treatment effectiveness.

A unique amino acid for brain cancer therapy

Photodynamic therapy is often used to treat brain tumors because of its specificity — it can target very small regions containing cancerous cells while sparing the normal cells around it from damage. It works by injecting a drug called a photosensiti…

Study answers why ketamine helps depression, offers target for safer therapy

Scientists have identified a key protein that helps trigger ketamine’s rapid anti-depressant effects in the brain, a crucial initial step to developing alternative treatments to the controversial…

Multitasking brain mechanism examined

Multitasking is a difficult but highly desirable ability. New research examines a technique that might help us achieve it: reactivating the learned memory.

Spinal cord injury: Using cortical targets to improve motor function

New research provides the first evidence that cortical targets could represent a novel therapeutic site for improving motor function in humans paralyzed by spinal cord injury.

UV-sensing protein in brain of marine annelid zooplankton

Larvae of a marine ragworm Platynereis dumerilii have been studied as a zooplankton model, and possess photoreceptor cells in the brain to regulate circadian swimming behavior. This study revealed that a photoreceptive protein in the brain photorecepto…

Select memories can be erased, leaving others intact

Different types of memories stored in the same neuron of the marine snail Aplysia can be selectively erased, according to a new study.

Rare cells are ‘window into the gut’ for the nervous system

Specialized cells in the gut sense potentially noxious chemicals and trigger electrical impulses in nearby nerve fibers, according to a new study, report scientists.

Alzheimer’s disease study links brain health, physical activity

People at risk for Alzheimer’s disease who do more moderate-intensity physical activity, but not light-intensity physical activity, are more likely to have healthy patterns of glucose metabolism in their brain, according to a new study.

People who go to bed late have less control over OCD symptoms
