The cognitive and regulatory processes within higher-order brain structures that regulate the hypothalamic–pituitary–adrenal (HPA) axis and the limbic system orchestrate a complex stress response system. In order to address this, we collected 48 tissue samples from the amygdala (Amy), hippocampus (Hip), thalamus (Tal), hypothalamus (HT), pituitary gland (PG) and adrenal gland (AG). We applied ATAC-seq, a method for profiling a...
