Krista Wahlstrom: Investigating Amygdala's role in spacial memories

PTSD and Alzheimer's are two devasting neurological conditions that impact millions of people with no readily available cure. To solve these memory mysteries, scientists must first understand how the brain functions at a more basic level.

Krista Wahlstrom, a doctoral candidate in Psychological and Brain Sciences at the University of Iowa, is investigating how the almond-shaped brain region called the amygdala plays a role in the storage of spatial memories. She uses a technique called optogenetics, which allows her to stimulate brain regions and pathways using light, to excite or inhibit certain neural circuits.
