Melatonin is a hormone known to promote sleep, but its underlying mechanisms are unknown. Now, researchers have discovered how melatonin suppresses neurons in the brain that keeps you awake and alert. These findings could lead to new therapies for those who suffer from insomnia.

A new study shows how specific neurons can process sensory information about temperature and facilitate a change in behavior to adapt to the climate.

Researchers have identified electrical activity in the brain that is specific to the start of migraines. The new study reports spreading depolarization can be seen as a migraine begins, and an electrical current can be used to stop it in its tracks.

Adolescent drinking is associated with changes in the metabolite profile, a new study shows. 

Scientists are using big data and artificial intelligence to map neural networks in the brain. The new technology could help to better understand the progression of neurodegenerative diseases.

Sound and object motion can be used to change perceptions about body size, according to a new study.

Researchers report impairments in the neuroprotective communication between neural blood vessels, astrocytes and neurons may be an early factor in how high blood pressure may impair cognitive function.

A new study confirms a link between a number of autoimmune diseases and an increased risk of developing psychosis.

Autonomous Sensory Meridian Response (ASMR) – the relaxing ‘brain tingles’ experienced by some people in response to specific triggers, such as whispering, tapping and slow hand movements – may have benefits for both mental and physical health, according to new research.

Researchers have developed new neural implants that enable targeted delivery of drugs deep into brain structures.

A new study reports specific alterations in signaling circuits associated with memory can induce an abnormal response in neurons, which is linked to the aging process and cognitive decline.

Researchers say the combination of low muscle mass and strength in the context of high-fat mass, could be a predictor of cognitive function in older adults. 

Obstructive sleep apnoea (OSA) is associated with changes to the structure of the brain that are also seen in the early stages of dementia, according to a study published in the European Respiratory Journal.

Finally, this week, a new study reports a mother’s diet during pregnancy may have an effect on the composition of her child’s gut bacteria.
