Endorphins may contribute to the positive effect of exercise on anxiety and depression. [43] The same phenomenon may also play a role in exercise addiction . Regular intense exercise may cause the brain to downregulate the production of endorphins in periods of rest to maintain homeostasis , causing a person to exercise more intensely in order ...
The opioid receptors are distributed throughout the central nervous system and within the peripheral tissue of neural and non-neural origin. They are also located in high concentrations in the periaqueductal gray , locus coeruleus , and the rostral ventromedial medulla .
It is located at the center of the gland, being surrounded by the adrenal cortex. [1] It is the innermost part of the adrenal gland, consisting of chromaffin cells that secrete catecholamines , including epinephrine (adrenaline), norepinephrine (noradrenaline), and a small amount of dopamine , in response to stimulation by sympathetic ...
One of the most important functions of the hypothalamus—it is located in the brain adjacent to the pituitary gland—is to link the endocrine system to the nervous system via the pituitary gland.) Other organs, such as the kidneys, also have roles within the endocrine system by secreting certain hormones.

Enteroendocrine cells are specialized cells of the gastrointestinal tract and pancreas with endocrine function. They produce gastrointestinal hormones or peptides in response to various stimuli and release them into the bloodstream for systemic effect, diffuse them as local messengers, or transmit them to the enteric nervous system to activate nervous responses.
It’s “basically the basis of learning,” says Wise, adding that “in neuroscience it’s called Hebb’s rule: the neurons that fire together, wire together.” In other words, practice ...
Schematic of the HPA axis (CRH, corticotropin-releasing hormone; ACTH, adrenocorticotropic hormone) Hypothalamus, pituitary gland, and adrenal cortex The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a ...
