Martin, Kiley; Musaus, Madeline; Navabpour, Shaghayegh; Gustin, Aspen; Ray, W. Keith; Helm, Richard F.; Jarome, Timothy J. – Learning & Memory, 2021
Strong evidence supports a role for protein degradation in fear memory formation. However, these data have been largely done in only male animals. Here, we found that following contextual fear conditioning, females, but not males, had increased levels of proteasome activity and K48 polyubiquitin protein targeting in the dorsal hippocampus, the…

The extinction of delay fear conditioning relies on a neural circuit that has received much attention and is relatively well defined. Whether this established circuit also supports the extinction of more complex associations, however, is unclear. Trace fear conditioning is a better model of complex relational learning, yet the circuit that…
