When a new mom gazes at her baby, it’s not just her mood that lights up - it’s also a brain region associated with emotion processing, according to a new study from the University of Wisconsin-Madison.
The study, published in the current issue of NeuroImage, explored what happens in the brain when mothers are shown pictures of their babies, as well as images of unfamiliar infants. While all the photos increased the amount of activity in a part of the brain associated with emotion, the images of the mothers’ own infants generally increased activity even more, suggesting that this brain region may be involved in maternal attachment.
Motivations for the study originated from a lack of reliable knowledge about positive emotions, says Jack Nitschke, a neuroscientist and assistant professor of psychiatry and psychology at UW-Madison. "We know that depression and anxiety are not accompanied solely by an increase in negative emotions, but also by a decrease in positive ones," says Nitschke, lead author of the paper. "Yet we know much more about negative emotions than about positive emotions."

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
