The Impact Of Chronic Stress, Traumatic Experiences And Genes On Behavior, Colten Brown

Research on Capitol Hill

Chronic unpredictable stress (CUS) alters neurotransmission and remodels neural circuits involved in learning, attention and decision making.

Glial-derived neurotrophic factor (GDNF) is essential for the function of neurons. Regulation of GDNF during stress is linked to resiliency while the inability to regulate it causes behavioral alterations.

We investigated the effects of CUS on latent inhibition (LI), a measure of selective attention expressed in this model as freezing behavior.
