About this trial

The goal of this research study is to learn how the brain areas that plan and control movement interact with the areas responsible for hearing and perceiving speech in healthy adults and people who have had cerebellar strokes. The main questions it aims to answer are:

1. What regions of the brain's sensory systems show changes in their activity related to speech? 2. To what extent do these regions help listeners detect and correct speech errors? 3. What is the role of the cerebellum (a part of the brain in the back of the head) in these activities?

Participants will be asked to complete several experimental sessions involving behavioral speech and related tests and non-invasive brain imaging using electroencephalography (EEG) and functional magnetic resonance imaging (fMRI).
