Research Overview

RESEARCH INTERESTS: The focus of the laboratory is on functional brain mapping in awake, nonrestrained animals of behaviors that are difficult to examine with conventional neuroimaging protocols (PET, SPECT, fMRI) as these require sedation and restraint of the subject--interventions which eliminate all but the most basic behaviors. To aid in this task, we have designed and validated the use of an implantable, miniature, infusion pump (MIP) for the administration of radiotracers by remote activation in freely moving animals. Current work focuses on the miniaturization of the MIP for use in mice, as well as developing the MIP as an interface for use with novel radiotracers to allow an expanded use of PET for functional neuroimaging in freely-moving animals. A complimentary area of active work is the development of methods of analysis of autoradiographic brain sections obtained from rodents. Ongoing projects include those evaluating the reorganization of brain function in response to lesions (Parkinsons models, traumatic brain injury, cerebral ischemia) and exercise training, projects evaluating functional brain activation in response to visceral pain (sex differences, fear conditioned visceral pain), a project evaluating the response of the brain to fearful stimuli in adult life after prior exposure to prenatal stress, and the characterization of the conditioned fear response in mice lacking the serotonin transporter.

The expertise of the laboratory include functional brain mapping, animal behavior, physiologic monitoring (EEG, EMG, EKG) and basic histochemistry.
