Researchers who have struggled for years to overcome stress have made an important step forward by discovering the center of stress in the brain.
According to the information announced at the medical congress held in Bristol earlier this month, the starting point of the stress reaction is in the ‘‘ hypothalamus, a walnut-sized region in the brain. Nerve cells in this area secrete the hormone "corticotropin" (Crh) in case of an undesirable situation.
This hormone causes the secretion of another hormone called "adrenocorticotrope" (ACHT). This hormone mixes with the blood and flows into the adrenal glands. The adrenal glands start to produce adrenaline and cortisol hormones, and fat cells start to spray sugar. Heartbeat accelerates, blood pressure rises in order to provide energy transfer to the muscles. In such situations, people cannot find opportunities for either sex or digestion.
However, after the danger passes, the body brakes, cortisol produced with adrenaline returns to its center in the brain. The alarm condition ends.
