Humans tend to be overly optimistic about the future, sometimes underestimating risks and making unrealistic plans, notes NIMH grantee Elizabeth Phelps, Ph.D., New York University. Yet "a moderate optimistic illusion" appears to be essential for maintaining motivation and good mental health. Using functional magnetic resonance imaging (fMRI), Phelps and her colleagues have now shown that such "optimism bias" may be rooted in the same brain circuitry as depression, which is marked by a tendency to be overly pessimistic. The same circuitry was also in play when this normal bias toward positive thinking was temporarily turned off by depriving the brain of the mood-regulating chemical messenger serotonin, in another recent fMRI study by NIMH intramural research psychiatrist Wayne Drevets, M.D., and colleagues.
