![]() ![]() Developmental changes in these distributed neural circuits may lead to age-related differences in reward-motivated memory and the underlying neural mechanisms. Reward motivation enhances memory through interactions between mesolimbic, hippocampal, and cortical systems, both during and after encoding. We then assessed the degree of overlap between the high > low reward contrast map (that included all trials irrespective of subsequent accuracy) and the high > low reward correct contrast map. We assessed high > low reward correct as the contrast of interest. ![]() Due to the presence of an empty correct trial task regressor in a run, five participants lost runs, and one of those participants (who already had partial data due to a run eliminated for excessive motion) had to be excluded from this follow-up analysis (thus, n = 88). To assess the extent to which the reported encoding activations were reflective of successful memory encoding processes, the encoding fMRI analysis as described in the Materials and Methods was rerun with the following four task regressors that reflect correct or incorrect specific source memory after 24 h: high-reward correct trials, low-reward correct trials, high-reward incorrect trials, and low-reward incorrect trials. Extended Data Figure 3-1: Encoding brain activation maps for high > low reward contrast, high > low reward restricted to trials with correct specific source memory after 24 h, and their overlap. ![]()
