Neural correlates of reward-directed action and inhibition of action

Description: In a sample of 35 healthy human adults, we examined brain activations to action and inhibition of action in a reward go/no-go task, with approximately ⅔ go and ⅓ no-go trials. Correct go and no-go trials were rewarded with $1 or ¢5 in reward sessions. A whole-brain two-way ANOVA of response (go vs. no-go) and reward (dollar vs. nickel) was conducted. The following results have been uploaded: 1. Two-way whole brain ANOVA: response (GS vs. NGS) x reward (dollar vs. nickel). This analysis shows at the group level the main effect of response, main effect of reward, and interaction effect. 2. Two whole-brain multiple regressions with 1) GS dollar minus GS control RT as the predictor (contrast GS dollar > NGS control), and 2) NGS dollar minus NGS nickel rate as the predictor (contrast NGS dollar > NGS nickel). These two analyses show at the group level of the neural correlates of relevant task performance measures. 3. T-test at the group level analysis showing the following contrasts: 1) (GS_reward-GS_control)>(NGS_reward-NGS_control), 2) GS_reward>GS_control, and 3). NGS_reward>NGS_control
