The brain circuitry underlying emotion includes several territories of the prefrontal cortex (PFC), the amygdala, hippocampus, anterior cingulate, and related structures. (virginia.edu)
We found abundant Tac4 expression in the hypothalamic-pituitary-adrenal axis, but Tac4 mRNA was also detected in the hippocampus, amygdala, somatosensory and piriform cortices in mice, and in the frontal regions and the amygdala in humans. (bvsalud.org)
In contrast, the hippocampus functions as a switch and "control center" (Jacobson and Sapolsky. (briantrappler.com)
The function of the hippocampus is to contextualize an event, tag it to an emotion, transform it into a language transcript, and finally download a coded file into the temporal lobe of the brain. (briantrappler.com)
The hippocampus and amygdala also function as endocrine brain structures . (briantrappler.com)
