Changes In Resting-State Functional Connectivity Following Delay And Trace Fear Conditioning Acquisition And Extinction, Douglas Hank Schultz

Theses and Dissertations

Consolidation is the process of stabilizing a recently acquired memory into a more permanent or durable form. Several studies with laboratory animals have uncovered valuable information about the process of consolidation, but less is known about the process of consolidation in healthy humans. The current study examined the consolidation of emotional memories in different brain circuits in healthy humans using resting-state fMRI. We used the acquisition and extinction of two variations of Pavlovian fear conditioning, delay and trace, which rely on slightly different circuits to examine changes in functional connectivity related to a general fear learning process and also to …
