Examining The Roles Of Gabaa Receptor Subtypes In Anxiety And Anxiolysis: Focusing On The Basolateral Amygdala, Yudong Gao

Theses and Dissertations (ETD)

The investigation of the differential roles GABA_A receptor (GABA_AR) subtypes play in mediating various behaviors such as fear and anxiety was an intriguing research topic over the past decade. At present, most evidence suggests that benzodiazepine (BZ)-induced anxiolysis is primarily mediated by GABA_ARs containing the α2-subunit (α2-subtype). However, there is conflicting evidence as to whether α1- and α3-subtypes might also be involved in BZ-induced anxiolysis. In an attempt to further discern the role played by different α-subtype GABA_ARs in BZ-induced anxiolysis both systemically and within the basolateral amygdala (BLA), a brain region crucial …
