Early-life stress causes digestive problems and anxiety in rats

Traumatic events early in life can increase levels of norepinephrine — the primary hormone responsible for preparing the body to react to stressful situations — in the gut, increasing the risk of developing chronic indigestion and anxiety during adul…

Mimicking deep sleep brain activity improves memory

It is not surprising that a good night’s sleep improves our ability to remember what we learned during the day. Now, researchers have discovered a brain circuit that governs how certain memories are consolidated in the brain during sleep. The study sho…

The brain needs cleaning to stay healthy

New research has revealed the mechanisms that keep the brain clean during neurodegenerative diseases.

New technique captures activity of an entire brain in a snapshot

With a new imaging tool, scientists are able to measure the activity of all the neurons in a mouse brain with unmatched precision. The method is widely applicable for studying how the brain functions both under normal conditions and in disease.

Brain picks up the beat of music automatically

A sense of rhythm is a uniquely human characteristic. Music cognition scientists discovered that the sense of rhythm – also known as the beat – is so fundamental to humans that we recognize patterns in music even without paying any attention or rec…

Difficult decisions involving perception increase activity in brain’s insular cortex, study finds

As the difficulty of making a decision based on sensory evidence increases, activity in the brain’s insular cortex also increases, according to researchers.

New discovery from the molecular machinery for depression and addiction

Researchers have described how a group of the brain’s transport proteins with important roles in depression and dependence overcome the step which limits their effectiveness. The discovery makes it possible to describe the full function of the transpor…

Researchers show experience plays strong role in early stages of brain circuit development

A new study suggests that external stimulation guides certain neurons’ early development so that inhibitory neurons split into two different types of neurons, each with a different job, adding another level of complexity and regulation to the brain’s c…

In brain-injured patients, a way to measure awareness or its impending return

The precise diagnosis and prognosis of recovery of consciousness of patients after a severe brain injury is a challenging clinical task, as some brain-injured patients retain certain levels of awareness despite appearing fully unresponsive. Now, resear…

Psychiatric disorders more common among workaholics, study finds

A new study found symptoms of OCD, ADHD, anxiety, and depression were much more common among adults who met the criteria for workaholism.
