Many of us run into problems when we try to make decisions. In a special section in the October 26 issue of the journal Science, Martin Paulus who is a professor in the Department of Psychiatry at the University of California in San Diego, has marshaled a growing body of evidence that human decision-making is inextricably linked to an individuals' need to maintain a homeostatic balance.
He goes on to suggest that psychiatrists may need to approach the treatment of psychiatric patients from a new direction: by understanding that such individuals' behavior and decision-making are based on an attempt to reach an inner equilibrium, in the same way that we try to being our temperature or blood pressure back to a set point. And if the thermostat is broken we may see mental illness and substance abuse.
This makes good sense: in the past decision-making process as a considered series of options and values, but that is not what we see in the clinic. People with addictions and some mental illnesses keep making bad choices, despite being intelligent and insightful.
Recent neuroimaging research shows strong support for the homeostatic nature of decision-making:
The insula is involved in processing interoceptive information: the body's internal state or sense of balance
Damage to the insula stops addiction to cigarettes
Some of the same brain structures implicated in the urge to take drugs are involved in other biological urges
The question addressed in part by this paper are whether changes in decision-making behavior and associated brain functions are a result of pre-existing characteristics - which may predispose individuals to use drugs - or occur as a consequence of long-term use.
This is certainly an interesting idea, and we shall have to see how it fits as we collect further data.
