excess they can be damaging. Atrophy of the hippocampus in humans and animals exposed to severe stress is believed to be caused by prolonged exposure to high concentrations of glucocorticoids. Deficiencies of the hippocampus may reduce the memory resources available to help a body formulate appropriate reactions to stress. When someone experiences a stressful event‚ the level of glucocorticoids in their blood rises. Via specific receptors in the hippocampus‚ this activates the hypothalamus‚ which then

higher the intensity of the emotion is experienced and the longer period of time it takes the person to calm down. Alongside the amygdala is the hippocampus. The hippocampus‚ shaped like a horseshoe‚ associates memory and attaches an emotion to it. People with BPD may have experienced a traumatic event as a child storing these memories in their hippocampus to later be retrieved as a teen or adult causing reckless or impulsive

most situations such as accidents or disease‚ but one of the greatest events in life that have a huge risk of brain damage are contact sports. Four brain structures that can be affected by a sports related injury to the head are the cerebellum‚ hippocampus‚ amygdala‚ and thalamus. These structures at risk of being damaged because they are in the center of the brain which‚ when the brain is pushed to one side applies pressure to that side of the brain‚ crowding these different brain structures together

A man by the name of Henry Molaison had a procedure performed on his brain at the Massachusetts Institute for Technology (MIT) in order to fix his epilepsy; however‚ instead he ended up possessing amnesia. The procedure caused damage to the hippocampus and the amygdala. His frontal lobe received to drilled holes and parts were suctioned out.The unintentional damage‚ which became secretive information‚ was an unreported lesion to the frontal lobe of Molaison’s brain. Due to the controversial damage

alcohol damage the hippocampus and prefrontal cortex areas of the brain which are still developing in college-aged students. The hippocampus is the area of the brain used for learning and memory. In one study‚ "Dr. Michael De Bellis at the University of Pittsburg Medical Center used magnetic resonance imaging to compare the brains of 14-21-year-olds who abused alcohol to the brains of those who did not. The longer a person had had a drining problem‚ the smaller his hippocampus - by about ten percent

Why would the closure of a potassium channel in the presynaptic axon terminal change the amount of Ca2︎ entering and change the amount of neurotransmitter released? Serotonin(5-HT) receptor on the sensory axon terminals is a G-protein-coupled metabotropic receptor. Stimulation of this receptor leads to the production of intracellular second messengers‚ cAMP‚ which
