This small nucleus contains almost half of all the brain neurons that use norepinephrine as a neurotransmitter. The locus coeruleus also projects its axons to those parts of the brain that may be associated with panic disorders (the amygdala, hippocampus, septum, cortex, brainstem, reticular formation, etc). Stimulating an animal's locus coeruleus, like stimulating its amygdala, produces anxiety behaviours.
In addition to memory loss, this is also why you experience the anxiety gaze (staring blankly) and brain fog from time to time. Your brainâs ability to transmit information, like memories, is temporarily affected by the stress hormones you release when you are feeling high anxiety or prolonged stress.
