The sgACC, in particular, has long been a spotlight of various studies simply because previously studies have discovered depressed patients to show overactivity from the sgACC, which is recommended to normalize on recovery after treatment [213–216]. A the latest study in nonhuman primates demonstrated that ketamine is indeed capable to reverse the depressive-like impairments and metabolic improvements produced by the overactivation from the sgACC [217].
