Notes
We studied Dicranophorus sp., Platyias quadricornis (Ehrb.) and Rotaria tardigrada (Ehrb.). These rotifers systematically distinct from each other, show the same pattern of the catecholaminergic (CA-ergic) part of the nervous system. It is formed of a small (23-24), but steady number of neurons characteristic for each species. Three types CA-ergic neurons are described. The size of neurons vary from to two to ten um. The distribution of the brain neurons is correlated with body shape. Such a type of nervous system is topographically comparable to the concentrated orthogon of the flatworms.
