Distant regions of the human brain are wired together by surprisingly few connections

Understanding how the brain functions, particularly how information is processed during different activities, is difficult without knowing how many axons are in the brain and how many connect different functional regions. A new study shows that despite…

Researchers develop new antibody test to diagnose multiple sclerosis

Researchers have validated a new antibody test to diagnose multiple sclerosis (MS), a potentially disabling disease of the brain and spinal cord.

Limiting energy in neurons exacerbates epilepsy

Epilepsy, one of the most common neurological disorders, is characterized by the spontaneous repetition of seizures caused by the hyperactivity of a group of neurons in the brain. Could we therefore reduce neuronal hyperactivity, and treat epilepsy, by…

Exercise holds even more heart health benefits for people with stress-related conditions

Regular physical activity had nearly doubled the cardiovascular benefit in individuals with depression or anxiety, compared with individuals without these diagnoses, according to a new study.

How the gut communicates with the brain

New research has discovered how the enteric nervous system — or ‘second brain’ — can communicate with both the brain and spinal cord, which up until now had remained a major mystery. The study found specialized cells within the gut wall release serot…

One in four children who have suffered a minor head injury is liable to suffer from chronic post-concussion syndrome, study finds

A new study found that one in four children (25.3 percent) who have been discharged from the emergency room after a mild head injury are misdiagnosed and continue to suffer from persistent post-concussion syndrome for many years.

Maternal socialization, not biology, shapes child brain activity

Children of mothers with clinical depression are at three times greater risk to develop depression themselves than are their low-risk peers. Researchers are working to understand the neural underpinnings of the risk, and some studies have shown altered…

Researchers control brain circuits from a distance using infrared light

Scientists have developed the first non-invasive technique for controlling targeted brain circuits in behaving animals from a distance. The tool has the potential to solve one of the biggest unmet needs in neuroscience: a way to flexibly test the funct…

Oleic acid — a key to activating the brain’s ‘fountain of youth’

A team of researchers reveals that oleic acid produced in the brain is an essential regulator of the process that enables learning and memory and supports proper mood regulation. The finding has paved the path to discovering potential new therapeutic s…

Shining a light on protein aggregation in Parkinson’s disease

A novel system to control protein aggregation in a model of Parkinson’s disease may answer longstanding questions about how the disease begins and spreads, according to a new study. Initial results suggest that aggregation of the protein alpha-synuclei…
