Table 1.

Neuron types, size, and density.

Type	Soma radius (μm)	Density (neurons/ μm3) *(/ μm2)
Golgi cell (GoC)	8	9 × 10−6
Glomerulus (Glom)	1.5	3 × 10−4
Granule cell (GrC)	2.5	3.9 × 10−3
Purkinje cell (PC)	7.5	0.45 × 10−3*
Basket cell (BC)	6	0.5 × 10−4
Stellate cell (SC)	4	0.5 × 10−4
DCN glutamatergic cell (DCNC)	10	5 × 10−7

The table reports the density of neurons in the layer volume (neurons/μm³),

^*except for PCs for which the planar density is used (neurons/μm²). Data for Glom, GrC, GoC, PC, SC, BC from Korbo et al. (1993). The density of DCNC was estimated from the ratio of PCs to DCNCs (Person and Raman, 2012).
