Genetically determined differences in brain response to a primary food reward.

The Journal of neuroscience : the official journal of the Society for Neuroscience - 17 Feb 2010

Abstract excerpt

Combining genetic and neuroimaging techniques may elucidate the biological underpinnings of individual differences in neurophysiology and potential vulnerabilities to disease. The TaqIA A1 variant is associated with diminished dopamine D(2) receptor density, higher body mass, and food reinforcement. It also moderates the relationship between brain response to food and future weight gain. This suggests that the...
