Opposing effects of dopamine antagonism in a motor sequence task - tiapride increases cortical excitability and impairs motor learning

Opposing effects of dopamine antagonism in a motor sequence task - tiapride increases cortical excitability and impairs motor learning

The dopaminergic system is involved in learning and participates in the modulation of cortical excitability (CE). CE has been suggested as a marker of learning and use-dependent plasticity. However, results from separate studies on either motor CE or motor learning challenge this notion, suggesting...
