Abstract

The distribution of the activity of acetylcholinesterase (AChE) was studied enzyme-histochemically in the periventricular substance of the central nervous system of fishes, amphibians, reptilia, birds and mammals. In the liquor contacting neuronal territories known until now - the areas containing nerve cells which are directly contacting the cerebrospinal fluid by ventricular processes and special nerve terminals - and also in other periventricular nuclei, AChE-positive liquor contacting neurons were found. Most of these strongly AChE-positive nerve cells could be observed in the periventricular gray of the hypothalamus and around the central canal of the spinal cord of the species studied. In the telencephalon and mesencephalon of reptilia, only sporadic, AChE-positive liquor contacting neurons occured. In the hypothalamus, the following territories contained AChE-positive liquor contacting nerve cells: the paraventricular organ, preoptic recess organ, preoptic and paraventricular nuclei, infundibular nucleus, nucleus tuberis lateralis, the periventricular, hypothalamic nucleus, lateral recess of amphibians, mamillar recess of fishes, and the vascular sac. AChE-positive liquor contacting neurons were described around the central canal on the level of the urophysis and in all other segments of the spinal cord. Activity of AChE is not only present in the perikarya of the liquor contacting nerve cells, but also in their ventricular processes and liquor-terminals. The AChE-positive cells of the various territories investigated, were discussed with regard to a "cholinergic" component of the liquor contacting neuronal system.
