CRH and depressive symptom measurement: Mice which lack the GABAAR δ subunit (Gabrd-/- mice) exhibit depression-like behaviors restricted to the postpartum period and deficits in maternal care (Maguire and Mody, 2008), a finding which has been attributed to the disinhibition of CRH neurons (Sarkar et al., 2011) resulting in elevated corticosterone levels during the peripartum period (Maguire and Mody, 2016).
