Abstract
The size distributions of populations of neuronal somata, dendrite internode branch lengths and synapse areas are presented. These all show a positive skew and in some cases this is pronounced.
Arguments are put forward to explain this consistent finding. In general the tendency of biological systems to optimise their size on a minimising principle will be a contributory factor. In particular the excitable elements of the central nervous system possess the additional feature that size controls their physiological sensitivity and this is advanced as a major factor in the evolution of the experimental findings. The estimation of the majority of these measurements is possible only by the use of stereological techniques.
