Clinicаl Cаse (next twо questiоns): Sаmantha is a 65yо patient undergoing physical therapy to recover from a knee arthroplasty surgery. During her initial treatment sessions, she performs quad sets for strengthening. Samantha’s physical therapist consistently praises her (“Good job!”) each time she successfully completes a set of quad exercises. Over the course of her first 3 treatment sessions, Samantha becomes conditioned to expect praise whenever she performs quad sets. If Samantha’s physical therapist praises her after performing her quad sets at her next treatment session, what is the MOST likely effect on Samantha’s dopamine neurons?
