Mechanisms of Open and Hidden Placebo in Stroke Recovery

Description

This trial aims to investigate whether placebo in isolation (open and hidden) has a specific neural signature in stroke subjects thus providing a novel mechanism to explain placebo effects that can be used to ultimately enhance stroke rehabilitation therapies.
