Rationale
The precise neural circuitry that encodes fear memory and its extinction within the brain is not yet fully understood. Fearful memories can be persistent, resistant to extinction, and are often associated with psychiatric disorders, particularly post-traumatic stress disorder (PTSD). This study investigated the microtopography of neurons activated during the recall of an extinguished fear memory,
as well as the influence of time on this neural organisation.
