by Viviana Greco July 2, 2023 in Anxiety, Depression, Neuroimaging Anxiety and depression are widespread mental health issues in our society. They often occur together and can increase the risk of developing other mental and physical health problems. Researchers are using neuroimaging studies to better understand the underlying causes of these disorders. However, most studies have...
The human brain is an incredibly complex organ that is inherently dynamic. Even viewing a simple, static image on a screen unleashes a vast network of neural activity in our brains. But the invasive nature of the techniques necessary for examining such activity means that scientific studies frequently focus on non-human subjects. But now an international research...

To examine the human brain and better understand its functions, neuroscientists...
by Mariah Chuprinski, Pennsylvania State University Biomedical engineering researchers discovered that during rest, individual neurons fire in organized cascades, triggering activity across the brain. Here, the spiking activity of five individual neurons is shown in a section of a mouse brain. Credit: Xiao Liu When mice rest, individual neurons fire in seconds-long, coordinated cascades, triggering activity across...

UNIVERSITY OF MALAGA The loss of oligodendrocytes (OLs) -highly specialized cells of the brain that produce myelin, an essential structure enabling an efficient transmission of electrical signals and the support of neural activity- is a frequent condition in patients suffering neurodegenerative diseases. Researchers of the Department of Cellular Biology, Genetics and Physiology of the University of...
Researchers can now predict whether an individual will remember or forget based on their neural activity and pupil size. “As we navigate our lives, we have these periods in which we’re frustrated because we’re not able to bring knowledge to mind, expressing what we know,” says Anthony Wagner, a professor in the social sciences at Stanford...
