Neural Mechanisms of Anxiety During Opiate Withdrawal: Role of the Ventral Tegmental Area and Extended Amygdala

Current Position:

Assistant Professor, Miami University, Department of Psychology

Undergraduate Institution and Major/Degree:

St. Olaf College, BA, Biology, 2006

Major Advisor(s):

Jonathan Gewirtz, Ph.D.

Research Description:

Anxiety is a common symptom reported during opiate withdrawal.  In the Gewirtz lab, I am investigating the neural substrates of this negative affective state.  Our primary model is the withdrawal-potentiated startle phenomenon in which withdrawal from an acute dose of morphine results in potentiation of the acoustic startle reflex.  Current focus is on the role of corticotropin-releasing factor, norepinephrine, and dopamine systems.
