15 July 2008 Some individuals earn rewards more successfully than others, but it has been unclear what brain changes underlie these differences. Tye et al. report that reward learning performance depends upon increased activity and synaptic strength in the amygdala, a brain area important for emotional learning. The level of learning attained by individual animals was strongly correlated with the degree of synaptic strength enhancement. This enhanced understanding of brain changes during reward learning will aid the development of therapeutic interventions for deficits in natural reward learning or cases of aberrant reward learning, such as drug addiction, or eating disorders. <article> |
