In the brain, cortisol binds to receptors that are found in the hippocampus and amygdala, which are important brain regions for learning and memory past work has found that inducing stress, thereby increasing cortisol, during or after learning benefits memory consolidation, while increasing cortisol during retrieval hinders recall.

We also report effects in bilateral hippocampus and amygdala at p brain effects at a p 0001 uncorrected threshold). The stress response involves activation of a brain region known as the amygdala, which sends a signal alerting the organism to the threat stem cells in the hippocampus although these effects .

Additional neuroimaging studies of the amygdala, hippocampus, and the rest of the limbic system, along with measurement of dopamine and other brain chemical transmitters during the learning process, reveal that students' comfort level has critical impact on information transmission and storage in the brain. The effects of stress hormones on learning are mediated by these receptors in the hippocampus and amygdala however, research in rodents points to the involvement of other brain regions in stress-related learning. Currently there is extensive evidence indicating that limbic areas such as the hippocampus, the pfc and the amygdala are crucially involved in regulating stress effects on memory through the interaction of stress hormones and stress-activated neurotransmitters (roozendaal et al, 2009, sandi, 2011, ulrich-lai and herman, 2009).
