Name:	Neocortex primary visual layer 5 corticopontine/tectal pyramidal cell
Description:	Pyramidal neuron with soma located predominantly in the upper middle part of layer 5. These neurons have medium to large somas with 5 or 6 primary basal dendrites (4-7 primary basal dendrites) and a single apical dendrite ascending to layer 1. Double labeling experiments show that these cells send collaterals to the pontine nucleus and the superior colliculus. It is possible that all cells sending projections to these regions send collaterals, but the presence of populations of cells sending projections to only the superior colliculus or the pontine nuclei cannot be ruled out.^[1]

No corticotectal or corticopontine neurons were observed with terminal dendrites ending below layer 1. Basal dendrites were restricted primarily to layer 5 but occasionally spread into lower layer 4 or upper layer 6.
