The nucleus raphe magnus of the cat. II. Quantitative analysis of axosomatic synapses.
Quantitative analysis of axosomatic synapses in the nucleus raphe magnus of the cat showed great variations in their number, shape and size. There exist some relations between the size of perikarya and the number and size of the synaptic knobs. In the small neurons the number and size of synapses was smaller than in the large neurons, but there exist some exception from this rule. The observed morphological differences can be ascribed to different functional significance of various neurons.
