Food Insecurity Has Lasting Impacts on the Brains and Behavior of Mice

While food insecurity is a problem for a growing segment of the U.S. population — made even worse by the coronavirus pandemic — few studies have looked at the effect that feast or famine has on the developing brain in isolation from other factors that contribute to adversity. A new study by neuroscientists at the University of California, Berkeley, simulated the effects of food insecurity in juvenile mice and found lasting changes later in life.

Berkeley Talks: How We Learn Language Across Communities and Cultures

In Berkeley Talks episode 149, Mahesh Srinivasan, an associate professor in UC Berkeley’s Department of Psychology, discusses the importance of child-directed speech in language learning, how poverty may suppress parents’ speech to their children and how children learn language from overheard speech.

Scientists Work to Unravel Mysteries of How Anxiety, PTSD Affect Brain

A group of Bay Area scientists have unraveled some surprising secrets about post-traumatic stress disorder or PTSD which one day could lead to better therapies and treatments. At UC Berkeley, neuroscientist Dr. Daniela Kaufer and now UCSF post-doc Kimberly Long — along with UCSF and San Francisco scientists Radiologist Dr. Linda Chao and Psychiatrist Dr. Thomas Neylan — may have provided a convincing reason why some people are resilient to trauma and others are susceptible. According to statistics, 70 percent of American adults experience at least one traumatic event in a lifetime. Twenty percent of those will develop PTSD, and their symptoms vary dramatically. In their research, the scientists made two important discoveries: that anxiety and traumatic stress are linked to increased myelin in a part of the brain where there is less myelin; and that where the increased myelin is found correlates to the particular symptom. For more on this, see our story at Berkeley News.

Anxiety and PTSD Linked to Increased Myelin in Brain

A recent study links anxiety behavior in rats, as well as post traumatic stress disorder (PTSD) in military veterans, to increased myelin — a substance that expedites communication between neurons — in areas of the brain associated with emotions and memory.
