[16] This effect has been correlated to altered function and structure in somatosensory cortices and an increased ability to decouple regions in the brain associated with the cognitive appraisal of pain ( anterior cingulate cortex and dorsolateral prefrontal ...
The pain from these contractions can cause mobility limitations and a tense feeling within the muscle, he says. While they’re usually harmless, muscle cramps are undoubtedly uncomfortable.
When a person is in a stressful environment, the brain is set up to function at a higher level in the areas that have to do with avoiding dangers and fears— like the amygdala, which makes you ...
The model attempts to relate specific symptoms of depression to neurological abnormalities. Elevated resting amygdala activity was proposed to underlie rumination, as stimulation of the amygdala has been reported to be associated with the intrusive recall of negative memories.
“The amygdala was still activated the way it should be, but now the dorsolateral prefrontal cortex was also able to come online and exert influence, quieting down the amygdala signal, so it ...

Due to the changes in the brain as well as the issues associated with the change in physical and mental capacity, depression and low self-esteem are common side effects that can be treated with ...
