Brain areas necessary for reasoning identified

Researchers have identified the key brain regions that are essential for logical thinking and problem solving.

Researchers have mapped the hidden control system of vision

The smallest control system of vision in mammals has been mapped — a discovery that opens entirely new insights into how our vision works and how it can be affected by disease.

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 …
