"Visualization of fear memory generalization engrams in the infralimbic cortex"
Memory is thought to be encoded in sparse, distributed groups of neurons known as “engrams” Over time, engrams are dynamic. It is also known that memories lose specificity with the passage of time. A fundamental question in neuroscience is how engram dynamics over time contributes to the fidelity of memory expression. One memory process consistently shown to change over time is the degree of generalization. Generalization refers to the transfer of conditioned responding to stimuli that resemble the original conditioned stimulus. This talk outlines research in our lab examining ensemble dynamics and the expression of fear memory generalization over time.
Hadley Bergstrom earned his BS in Psychology from the University of Oregon and MA and PhD in Psychology from George Mason University. He went on to train as a postdoctoral Fellow in the Department of Psychiatry and Center for the Study of Traumatic Stress at the Uniformed Services University School of Medicine. He then held a postdoctoral Intramural Research Training Award in the Laboratory of Behavioral and Genomic Neuroscience at the National Institutes of Health. He currently directs the Memory Neuroscience Lab at Vassar College.
The Bergstrom lab studies how memory is stored and retrieved in the brain. The lab is particularly interested in how memory associated with fear and reward are represented in neural circuits. His research program incorporates techniques for visualizing and manipulating memory storage and plasticity in the brain. Knowledge about how the brain stores memory is vital to understanding disorders of learning and memory, such as post-traumatic stress disorder (PTSD) and addiction.
