stress

- reaction of the body to deleterious forces, infections & abnormal states that disturb homeostasis. Laboratory: - increased serum IL-6 [2] Special laboratory: - investigational MRI [2] - during social stress, activation of the amygdala correlates with the size of the city in which a person resides - activation of a part of the cingulate cortex correlates with upbringing in a large city [2] Comparative biology: - in male mice - stress activates neurons of the hypothalmic paraventricular nucleus to secrete corticotropin - inhibition of neurons in the hypothalmic paraventricular nucleus results in modest improvements in sleep, & more substantial gains in memory [3]
