Speech Motor Learning and Retention (Aim 2)

Description

The focus of this registration is Aim 2. Specific Aim 2 assesses the temporal order in which plasticity occurs in cortical motor and sensory brain areas during speech motor learning. Plasticity is assessed using measures of cortical excitability. Specifically, auditory, somatosensory and motor evoked potentials are elicited using single pulse TMS (motor), pure tone bursts (auditory), and mentalis nerve stimulation (somatosensory). Tests of cortical excitability are interleaved with trials involving speech motor adaptation. Cortical excitability is also measured using these same measures 24 hours after learning to assess retention.

The Speech Motor Learning and Retention Master Protocol is NCT06467292.
