Summary

The age at which conditioned reflexes are first able to be formed coincides, in rabbits with presence of third stage (mature) neurons in all the layers of the cerebral cortex. The morphological criteria of maturity are: apperance of formed Nissl bodies, differentiation of the nucleoli, and apperance of synaptic knobs on the terminal dendrites.
