Experiential diversity promotes well-being in animal models. Here, using geolocation tracking, experience sampling and neuroimaging, we found that daily variability in physical location was associated with increased positive affect in humans. This effect was stronger for individuals who exhibited greater functional coupling of the hippocampus and striatum. These results link diversity in real-world daily experiences to fluctuations in positive affect and identify a hippocampal–striatal circuit associated with this bidirectional relationship.

The raw geolocation datasets generated and/or analyzed during this study are not publicly available due to the inherently identifiable nature of geolocation data, but they are available from the corresponding authors on reasonable request. The processed data necessary to reproduce the central findings in the manuscript are available at http://github.com/manateelab/NatNeuro/.
Custom R scripts were used to analyze and plot all data. The main analysis code was used to calculate the mean and standard deviation for RE. Code is available online at http://github.com/manateelab/NatNeuro/.

This figure depicts the parameter estimates of the effect of day of week (DOW) on positive and negative affect from linear mixed-effects models that included RE, time of day EMA was collected, distance travelled, mean temperature and precipitation (from the modal location of that day for that participant), and cohort as predictors (n = 122 independent human participants). Of the variables in models, only day of the week was also significantly associated with PA, with PA lower early to mid-week relative to the weekend (F(3834) = 2.8, p = 0.011). Both temperature (B = 0.062, t(3835) = 2.585, p = 0.01) and day of the week (F(3835) = 3.0, p = 0.006) were significantly associated with negative affect, which was greater on higher temperature days and in the early to mid-week relative to the weekend. Error bars represent standard error of parameter estimate.
