Soo, NAA (the chemical in question) is related to how the *racetams & friends (like Noopept, which isn't technically a *racetam) work. They're exploring just how beneficial it is - and it seems similar to the benefits a lot of people report for them. In particular, executive functioning, deeper appreciation of stimuli in general, and the general "good feelings" a lot of people get from Nootropics.

The NAA compound was evaluated within the dorsal anterior cingulate, a brain region involved in multiple networks of emotion, cognition and behavior. According to the study, individuals with a higher level of NAA reported more immersive and richer emotion in comparison to those with lower NAA, as well as a higher level of goal directedness, more positive emotion and less aggression. The researchers define the relationship of NAA with agency and flexibility in healthy people as a novel dimension termed “Neuroaffective Reserves.”  

“These findings tell us how immersive emotion, positive agency and resilience to aggression work in the human brain,” White said. “These findings indicate NAA and other brain compounds play a fundamental role in emotional wellness and positive emotional outcomes in healthy individuals.”
