Relationship between emotionally arousing events and their capacity to modulate brain systems that encode new experiences into memory
My primary research interests are centered on understanding the relationship between emotionally arousing events and their capacity to modulate brain systems that encode new experiences into memory. A major focus of this research is to delineate the role brainstem nuclei play in this process. They are known to receive synaptic input regarding changes in peripheral autonomic and neuroendocrine states following emotional arousal and also are responsible for conveying this information to brain structures that regulate memory formation. A second but equally important objective of this research is to reveal how brainstem structures that are recipients of this information, affect memory formation by influencing neurotransmitter release in limbic structures such as the amygdala and hippocampus.We use a battery of behavioral learning tasks as well as in vivo microdialysis to identify the types of chemical transmitters that are released in the brain to affect memory storage.
