Listening to music after psilocybin therapy for treatment-resistant depression increases the pleasure people feel from music, and this increase correlates with a reduction in anhedonia (loss of pleasure). Nineteen patients received a low dose (10 mg) and then a high dose (25 mg) of psilocybin one week apart. Functional MRI scans before and after treatment showed that during music listening, functional connectivity between the nucleus accumbens (a brain reward region) and areas resembling the default mode network decreased after treatment. The findings suggest psilocybin therapy enhances music-evoked pleasure and point to a possible brain mechanism involving reduced connectivity in the default mode network.
