Sox14 Is Required for a Specific Subset of Cerebello-Olivary Projections.

We identify as an exclusive marker of inhibitory projection neurons in the lateral and interposed, but not the medial, cerebellar nuclei. neurons make up ∼80% of neurons in these nuclei and are indistinguishable by soma size from other inhibitory neurons. All neurons of the lateral and interposed cerebellar nuclei are generated at approximately E10/10.
