The article offers information on a research study by M.A. Penzo and colleagues that examined the role of the paraventricular nucleus of the thalamus (PVT) in the maintenance and retrieval of fear memories. It was unclear how PVT governed threat-induced behavioral responses. The PVT sends projections to both the amygdala (CeA) and the basolateral amygdala (BLA), which store fear-conditioned memories.
