The scans, which were done before and after treatment, showed the psilocybin treatment reduced connections within brain areas that are tightly connected in depression, including the default mode, salience, and executive networks, and increased connections to other regions of the brain that had not been well integrated.

There is a neuroplasticity hypothesis of depression whereby as a response to stress our brains change at the cellular level in a dysfunctional way. This has been demonstrated by studies in mice, brain imaging and postmortems of depressed patients. Namely these changes are: Reduced synapse (connection) formation between neurons.

In particular, the amygdala in depressed people is more active than in people without depression when exposed to a negative stimulus such as a sad face. That trial compared brain scans from 32 people with depression with those from 25 healthy counterparts and confirmed that the former group had more activity in what is known as the default mode network, a collection of disparate brain regions that makes up the baseline, or default level of brain activity necessary to keep a body functioning.
