“…One potential explanation for this increased behavioral efficiency is that CB 1 R agonism attenuates the aversive emotional state associated with impending punishment. Systemic CB 1 R activation in humans has been associated with attenuated anxiety and stress, and produces anti-fear effects (Rabinak et al, 2013;Childs et al, 2017;Cuttler et al, 2018), and complementary data from rodent models demonstrate that CB 1 R agonist treatments have been associated with reduced aversive learning, impaired fear memory acquisition, enhanced fear extinction learning, reduced stress responsivity, and anxiolysis (Kangarlu-Haghighi et al, 2015;Simone et al, 2015;Nasehi et al, 2016;Fokos and Panagis, 2010;Gobira et al, 2013;Kangarlu-Haghighi et al, 2015;Kinden and Zhang, 2015;Schreiber et al, 2018;Uttl et al, 2018). Interestingly, the suppressive effects of cannabinoids on anxiety, fear, and stress appear to stem from CB 1 R activation in the basolateral amygdala (BLA), which is also involved in the integration of information regarding risk of punishment and reward value (Ganon-Elazar and Akirav, 2009;Orsini et al, 2015b;Morena et al, 2016).…”
