Summary: Researchers discovered that pupil dilation can indicate levels of working memory. In a study, researchers observed that individuals whose pupils dilated more while performing memory tasks tended to have better working memory.

This relationship between pupil dilation and memory performance suggests that pupil metrics could potentially serve as non-invasive indicators of cognitive load and memory capacity. The study involved 179 undergraduate students who performed various working memory tasks while their pupil responses were monitored.

An international collaborative research team, including scientists from UQ’s Queensland Brain Institute (QBI), has discovered a novel mechanism underlying memory involving rapid changes in a specific DNA structure.

A study from the University of Michigan has shown that traumatic experiences during childhood may get “under the skin” later in life, impairing the muscle function of people as they age.

The study examined the function of skeletal muscle of older adults paired with surveys of adverse events they had experienced in childhood. It found that people who experienced greater childhood adversity, reporting one or more adverse events, had poorer muscle metabolism later in life. The research, led by University of Michigan Institute for Social Research scientist Kate Duchowny, is published in Science Advances.

Duchowny and her co-authors used muscle tissue samples from people participating in the Study of Muscle, Mobility and Aging, or SOMMA. The study includes 879 participants over age 70 who donated muscle and fat samples as well as other biospecimens. The participants also were given a variety of questionnaires and physical and cognitive assessments, among other tests.

A recent study published in the Journal of Neuroscience Research offers an intriguing perspective on the effects of regular cannabis use. Contrary to the commonly held view that cannabis has primarily negative impacts on mental health and behavior, the study suggests that regular cannabis users may have a heightened ability to understand the emotions of others. This enhanced empathetic ability is linked to increased connectivity within certain brain regions, particularly the anterior cingulate cortex, a key area involved in processing empathy.

Cannabis is one of the most widely used psychoactive substances worldwide, yet its impact on mental health and cognitive functions remains a subject of contentious debate. Traditional research predominantly highlights the negative consequences associated with cannabis use, particularly its potential to impair cognitive functions and contribute to mental health issues.

These studies often focus on how cannabis interacts with brain regions like the anterior cingulate cortex, which is known to have a high density of cannabinoid receptors and plays a significant role in cognitive processes such as decision making and emotion regulation.
