[Peripherial ATP-ases in the different components of the central nervous system of Periplaneta americana L. (author's transl)].

A smaller ATP-ase activity in the abdominal nerve cord of the Periplaneta americana L. was observed when compared by peripheral area with ganglia activity of the central nervous system which have more complex physiological functions. There was no significant difference in the enzyme distribution in the pro, meso, metatoraxic, subesophageal ganglia and the sixth abdominal ganglion.
