Cerebrocerebellar system and Türck's bundle.

The cerebellum is presently recognized as an important structure for cognitive, emotional, and behavioral integration and exerts such activities through its newer parts that belong to the cerebrocerebellar system. Two bundles relate the cerebral cortex to the cerebellum-an anterior (frontopontine) projection (Arnold's bundle) and a posterior (temporo-occipito-parietal-pontine) projection (Türck's bundle). The historical development and the controversies about the eponym of the bundle named after Türck is reviewed. Besides the researchers and authors that were in agreement with Meynert, of a tract he described, and apparently in a deliberate way named after Türck, others rose to contest the eponym, considering it a misnomer. Despite some controversies, this bundle deserves to maintain the name, Türck's bundle, to honor the outstanding researcher that described it and named it after a notable colleague, possibly as a tribute, and also to mark the difficulties that surrounded this episode of neurological history.
