2 · The way out — dentate, SCP, and the second crossing⑤ The cerebellar output of the lateral (cerebrocerebellar) hemisphere converges on the right dentate nucleus (the interposed/vermis circuits are not drawn here) → ⑥ out along the superior cerebellar peduncle → ⑦ and crosses the midline AGAIN at the SCP decussation in the midbrain.
⑧ Now on the left: the fibres reach the red nucleus and ⑨ the VL thalamus — the loop’s return station to M1 and premotor cortex → ⑩ back toward left M1. Loop closed.
Double crossing: the SCP decussation plus the pyramidal decussation below mean each cerebellar hemisphere controls the IPSILATERAL body via the contralateral cortex — that is why a right cerebellar lesion shows up as right-sided clumsiness.
