Grain cell layer

Lamina granularis

The grain cell layer

The grain cell layer, the inner layer of the cerebellar cortex , is 400-500 μm thick. It contains an astonishingly large amount - 40-50(100??) billion - mkt. Small nerve cells, so-called grain cells, i.e. just over twice as many nerve cells as the cerebral cortex is estimated to contain. The layer additionally contains unipolar brush cells, Lugaro cell bodies and Golgi cellbodies with an extraordinarily rich branched axon branch.
