Both the paravermal cerebelar cortex and the posterior interpositus nucleus are related to reflex and acquired eyelid responses, contributing to its proper performance, but not to its acquisition.

Role of cerebellar interpositus nucleus in the genesis and control of reflex and conditioned eyelid responses.
We have demonstrated in a previous study that (1) high-frequency stimulation in the interpositus nucleus at low intensities decreases the amplitudes of corticomotor responses recorded ipsilaterally, suggesting a decreased excitability of the pyramidal system, and (2) anodal DCS of the motor cortex reverts this depressive effect [4].
According to this brainstem-cerebellar model, the pontine nucleus receive projections from both cortical and subcortical structures implicated in conveying CSt information (auditory, somatosensory, visual and association systems) [131-134] and sending axons (MFs) directly to the cerebellar cortex and the DCN, particularly to the interpositus nucleus (IN) [135-137].
