The pontine nuclei are a part of the pons which store the memory of intention during motor activity. Corticopontine fibres carry information from the primary motor cortex to the ipsilateral pontine nucleus in the ventral pons, and the pontocerebellar projection then carries that information to the contralateral cerebellum. The pons is a knob on the brain stem. ... Memory is a function of the brain: the ability to retain information. ... The word intention admits a variety of meanings: Purpose is thoughtful and deliberate goal-directedness -- thus intentional behavior. ...
