Waldeyer Layers

Waldeyer's layers are layers of cerebellar cells described by the German anatomist Wilhelm Waldeyer in the late 19th century.

The cerebellum consists of three layers of cells - molecular, granular and Purkinje. The molecular layer consists mainly of stellar cells and basket cells. The granular layer contains granular cells. The Purkinje layer consists of large Purkinje cells located between the molecular and granular layers.

Waldeyer described the location and structure of these three layers of cerebellar cells. He also suggested for the first time that Purkinje cells are the main information processing cells in the cerebellum. The cell layers of the cerebellum are now named after Waldeyer as "Waldeyer layers". They play an important role in coordinating movements and maintaining balance.
