Brain regions related to dispositional optimism. (a) The regional gray matter density (rGMD) of the left putamen is positively associated with dispositional optimism. (b) The rGMD of the right putamen is positively associated with dispositional optimism. (c) A scatterplot showing the correlation between the left putamen and dispositional optimism. (d) A scatterplot showing the correlation between the right putamen and dispositional optimism. Age, sex, family socioeconomic status (SES), general intelligence, and total gray matter volume were adjusted in these analyses
