Associate Professor, Department of Cellular and Molecular Pharmacology
Department of Cellular and Molecular Pharmacology

Amiel Rosenkranz graduated from the University of Pittsburgh in 1997.  He remained at the University of Pittsburgh to earn the M. S. degree in 1999 and the PhD in 2002, both in Neuroscience.  Following postdoctoral work at the Baylor College of Medicine and University of Texas-Austin he joined the faculty of the Department of Cellular and Molecular Pharmacology of the Chicago Medical School in 2007.

Research

Neurophysiology of Emotion and Memory

A dysfunction in the production, influence or perception of emotion is at the core of several psychiatric disorders. The amygdala is part of a system that mediates the influence of emotion on behavior and memory formation. In this laboratory we examine 1) how the amygdala influences these processes, 2) how it changes during learning, and 3) how it is disrupted in animal models of psychiatric disorders.

Modulation of synaptic integration

Synaptic inputs can drive neuronal activity. Their influence on neuronal output will be determined, in part, by integrative properties of the neuron. These properties are influenced by many factors, including monoamines and peptides. In this laboratory we examine how integrative properties are modified, and what role the dendrites play in this modulation.
