The brain learns to filter out distracting stimuli over time

The human brain can learn through experience to filter out disturbing and distracting stimuli — such as a glaring roadside billboard or a flashing banner on the internet. Scientists have used electroencephalography (EEG) to show that early visual proc…

LSD analogue with potential for treating schizophrenia developed

Researchers have developed a new, neuroplasticity-promoting drug closely related to LSD that harnesses the psychedelic’s therapeutic power with reduced hallucinogenic potential.

How does our brain regulate generosity?

Are there areas of the brain, which regulate prosocial, altruistic behavior? Researchers have studied a very special group of patients and established that the ‘basolateral amygdala’ (part of the limbic system) plays an important role in this.

Stress, depression factor into link between insomnia, heavy drinking

A new study suggests that perceived stress and depression factor into the relationship between insomnia and hazardous drinking — perhaps not a surprise. But because the relationship between insomnia and heavy drinking goes in both directions, the infl…

How the brain controls movement under uncertainty

A new study by neuroscientists shows that our brain deals with different forms of visual uncertainty during movements in distinct ways. Depending on the type of uncertainty, planning and execution of movements in the brain are affected differently. The…

Police officers face twice the risk of traumatic brain injuries and PTSD, survey finds

Police officers are more than twice as likely to have traumatic brain injuries compared to the general population.

The brain resorts to myelin when other brain nutrients are depleted

Marathon runners experience reversible changes in their brain myelin. These findings indicate that myelin (a substance that surrounds the neurons) exhibits behavior that was previously unknown, and that it contributes towards the brain’s energy metabol…

How mothers adapt to the metabolic demands of nursing

Nursing poses major metabolic demands on mothers, to which they respond by eating more and saving energy to sustain milk production. There are significant hormonal changes during lactation, but how they lead to metabolic adaptations in nursing mothers …

AI models of the brain could serve as ‘digital twins’ in research

In a new study, researchers created an AI model of the mouse visual cortex that predicts neuronal responses to visual images.

Eight or more drinks per week linked to signs of injury in the brain

Heavy drinkers who have eight or more alcoholic drinks per week have an increased risk of brain lesions called hyaline arteriolosclerosis, signs of brain injury that are associated with memory and thinking problems, according to a new study.
