New research has identified the mechanisms that trigger disruption in the brain’s communication channels linked to symptoms in psychiatric disorders including schizophrenia.

Genetic analysis of human patients has shown that mutations in genes involved in synaptic communication can drive neuropsychiatric and neurological diseases such as autism spectrum disorder and Alzheimer’s disease.

Researchers have discovered a way to predict human emotions based on brain activity.

Working 55 hours or more per week is linked to a 33% greater risk of stroke compared with working a standard 35 to 40 hour week, according to the largest study in this field so far,  published in The Lancet.

The permanence of memories has long thought to be mediated solely by the production of new proteins. However, new research has shown that the electrical activity of the brain may be a more primary factor in memory solidification.

The hippocampus in the brain’s temporal lobe is responsible for more than just long-term memory. Researchers have for the first time demonstrated that it is also involved in quick and successful conflict resolution

A brief period of postnatal visual deprivation, when early in life, drives a rewiring of the brain areas involved in visual processing, even if the visual restoration is completed well before the baby reaches one year of age, researchers revealed in Current Biology.

New research published in the British Journal of Psychiatry suggests that serious disorders of mood such as bipolar disorder may be the price that human beings have had to pay for more adaptive traits such as intelligence, creativity and verbal proficiency.
