Weekly Neuroscience Update

Researchers have presented new findings which found after one session of aerobic exercise people showed reduced cravings for alcohol, lower levels of stress, and improvements in mood.

When our eyes move during REM sleep, we’re gazing at things in the dream world our brains have created, according to a new study. The findings shed light not only into how we dream, but also into how our imaginations work.

Measuring how the eyes’ pupils change in response to light—known as the pupillary light reflex—could potentially be used to screen for autism in young children, according to a new study.

Researchers have made an important discovery about the way our brains process the sensations of sound and touch. They found that sensory systems in the brain are closely interconnected, with regions that respond to touch also involved when we listen to specific sounds connected to touching certain objects.

A study into the effect of surprise on our memory has inadvertently discovered a method that might help us to perform better in exams.

Scientists have uncovered how dopamine connects subregions of the striatum essential for habit formation, findings that may change the overall understanding of how habits are formed—and could be broken.

New research finds the brains of people playing online video games synchronize, even when there is a physical distance between the players.

By estimating people’s brain age from MRI scans using machine learning, a team of researchers has identified multiple risk factors for a prematurely aging brain. They found that worse cardiovascular health at age 36 predicted a higher brain age later in life, while men also tended to have older brains than women of the same age, as they report in The Lancet Healthy Longevity.

Young people with 22q11.2 Deletion Syndrome have distinct and marked EEG differences in brain activity during sleep, which could influence psychiatric symptoms.

Tight control of blood sugar in teens with Type 1 diabetes may help reduce the disease’s damaging effects on the brain, effects which have been shown even in younger children, according to a study published in Nature Communications.

Tests of the brain’s electrical activity have revealed fentanyl’s effects over time and indicated that the drug stops people’s breathing before other noticeable changes and before they lose consciousness.

A newly developed artificial intelligence model can detect Parkinson’s disease by reading a person’s breathing patterns. The algorithm can also discern the severity of Parkinson’s disease and track progression over time.

A new study reveals how a molecule produced by astrocytes interferes with normal neuron development in a range of neurodevelopmental disorders.

People with an obsessive urge to constantly check the news are more likely to suffer from stress, anxiety, as well as physical ill health, finds a new study published in the peer-reviewed journal Health Communication.
