Really excited about a new study with @helleryeahz out today in @NatureNeuro showing that the daily diversity of one’s physical location is associated with increases in #positiveaffect!

Inspired by past work on #environmentalenrichment and #roamingentropy in rodents, we asked whether day-to-day changes in real-world human exploration were related to fluctuations in affect. 
Using #geolocation tracking and #experiencesampling over several months, we found that subjects in NYC and Miami reported greater #positiveemotion on days when they visited more novel and diverse locations. Afterwards, we brought subjects into the lab for a resting state scan.
We found that individuals whose positive affect was most strongly linked to their daily level of exploration exhibited greater functional coupling of the striatum and hippocampus, regions involved in the processing of reward and environmental novelty.
This relationship suggests that the known beneficial consequences of environmental enrichment extend across species to humans.
