This study aims to investigate whether speech motor memory is based on sensory systems rather than solely motor processes.
Evaluated speech motor learning through altered auditory feedback in a controlled trial.
Utilized transcranial magnetic stimulation (TMS) to disrupt auditory (STG), somatosensory (S1), or motor (M1) cortex.
Conducted retention tests 24 hours after TMS disruption to assess motor memory retention.
Disruption of STG or S1 impaired motor memory retention, while M1 disruption showed no difference compared to the control condition.
Findings suggest that sensory system plasticity is essential for effective speech motor learning and memory.
Effects of TMS were specific to speech motor learning and did not affect speech production.
