Abstract: | We studied Dicranophorus sp., Platyias quadricornis (Ehrb.) and Rotaria tardigrada (Ehrb.). These rotifers, systematically distant 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 of CA-ergic neurons are described. The sizes of neurons vary from to two to ten µm. 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. |
