Brain glucose metabolism shows a dramatic drop from full consciousness to the minimal conscious and persistent vegetative states.

Brain scans strongly predict return of consciousness in vegetative patients.

Researchers report a surgically implanted neuroprosthetic devices that coordinates the activity hip, knee and ankle muscles led to improved walking speed and distance for a patient with limited mobility following a stroke.

According to new research, dopamine signalling within the cerebral cortex can predict changes between neural networks during working memory tasks.

A region of the brain that responds to bad experiences has the opposite reaction to expectations of aversive events in people with depression compared to healthy adults. The study, published in Molecular Psychiatry, found that the habenula, a pea-sized region of the brain, functions abnormally in depression. The same team previously showed that the habenula was activated in healthy volunteers when they expected to receive an electric shock.

Researchers have identified a mechanism that keeps the brain clean during neurodegenerative diseases.

Older people are less willing to take risks for potential rewards and this may be due to declining levels of dopamine in the brain, finds a new UCL study of over 25,000 people funded by Wellcome.

Neuroscience researchers have identified a gene critical for human brain development.

According to a new study, the brains of people with schizophrenia may be able to reorganize and fight the illness.

Researchers report we recognize patterns in music automatically, even with no musical training.

Finally this week, a new study has identified a neural pathway involved in switching between habitual behavior and deliberate decision making.
