This is super interesting! Good article too - I feel like I understand the general ideas behind the experiments they ran.

The findings align pretty well with the observations we’ve seen with MDMA being effective treatment for PTSD.

Also kinda reminds me of how both humans and monkeys laugh when we think there’s something scary, then find out it’s not a threat. This study is on a longer time scale (across days, not a single moment), but a flood of dopamine to extinguish fear makes sense.

Hopefully follow-up studies will be done to look into what causes each region of the brain to sensitize to dopamine.
