Some psychology students study biofeedback — the process whereby people apparently learn to control automatic behaviours, such as blood pressure. A recent study suggests that the behaviour of the amygdala could be controlled in a similar way.
First of all, how does biofeedback work? Briefly, the process is that a person is given some kind of visual or auditory feedback of an unconsciously controlled process such as their blood pressure – so they can see or hear whether any behaviour on their part is reducing the undesirable activity (for example, high blood pressure). The activity might be breathing more slowly or using relaxation exercises. If the activity is successful this is reinforcing.
