Document Summary
Low hrv (also low levels of cognitive control) with high trait anxiety. Low hrv associated with behavioural inhibition in children: (cid:862)e(cid:454)tre(cid:373)e sh(cid:455)(cid:374)ess(cid:863, combination of high introversion and high neuroticism. Our tendency: physiology is fundamental, cognitive and behaviour follows. We would think that low heart variability leads to high levels of anxiety as a consequence. This is not true because as we see, if we treat anxiety with cbt, we get increases in hrv. Making changes physiologically through a purely psychological therapy. Through this we see cognitive first and then see physiological aspects following. Amygdala frontal cortex: cognitive component of anxiety, moderates vagal response lower or higher hrv temporal cortex. Hpa = hypothalamus, pituitary, and adrenal gland: these 3 structures very important in our normal response to stressful situations. Have external stressor leads to stimulation of hypothalamus to produce crh (corticotropin releasing hormone) finds its way to pituitary gland which is right next door.
