Psilocybin increases optimistic engagement over time: computational modelling of behaviour in rats
The model revealed that after receiving psilocybin, rats achieve more rewards through increased task engagement…
As optimism bias is associated with increased engagement with the world and depression is linked to diminished optimism… all experimental procedures were conducted in accordance with the Australian Code for the care and use of animals for scientific purposes and approved by the Monash Animal Resource Platform Ethics Committee (ERM 29143)… we hypothesised that psilocybin increased optimism by asymmetric belief updating, which was the main focus of these models; however, other parameters that have been associated with depression or optimism were also considered.
