Document Summary
The epinephrine liver glucose connection: bioenergetics and the brain. The flow of energy in cells is called bio-energenics, and the primary source of. Notes energy is glucose, which enters the brain via the cerebral vasculature. An arousing event activates the adrenal medulla to release epinephrine into the blood system where it binds to adrenergic receptors in the liver cell. This results in the liver secreting glucose into the blood where it enters the brain via the cerebral vasculature system. This figure illustrates that systemic injections of either epinephrine or glucose influence memory strength in a dose-dependent manner. (after. These data support the view that epinephrine may also modulate memory by binding to adrenergic receptors on the liver cells causing them to release glucose. Arousing events drive release of both norepinephrine and glucocorticoids, and they function in concert to regulate memory strength. The stress hormones epinephrine and glucocorticoids are made by different regions of the adrenal gland.
