Purkinje Cells are known for their beautiful and highly recognizable architecture. Their large, flat dendritic arbors receive and integrate thousands of inputs.
The larval zebrafish has become a popular model organism for studying the brain due in part to its genetic accessibility, rapid development, and amenability to imaging.
In the zebrafish genetic techniques can be used to express fluorescent indicator in specific brain structures. Here, the cerebellum.
Cerebellar granule cells are the most numerous neuronal cell type in the brain, estimated to account for well over half of all neurons in the human brain.
