SYNVEST imaging shows real 5-HT2A synaptic effects but no clean clinical correlation, disappointing simple neuroplasticity narratives.

A study called SYNVEST is using advanced brain imaging to look at whether psychedelics actually change the density of connections between brain cells by acting on a specific receptor called 5-HT2A (a docking point on brain cells that psychedelics latch onto). The scans will likely show that yes, something measurable changes in the brain. But researchers won't be able to clearly show that more brain-connection changes equals more symptom relief in patients — which is the headline the field was hoping to prove.
