Central Nervous Activity in the Earthworm

Central Nervous Activity in the Earthworm Ii. Properties of the Tension Reflex

SOME of the responses of a series of complete segments excised from the body of the earthworm have been described in the preceding paper (Collier, 1939). It was there shown that the rhythmic peristaltic reflexes are not initiated in the absence of the nerve cord. While the responses, of an isolated region of the worm, to touch are somewhat variable and exhibit several different components, the ...

ADENOSINE IN THE CENTRAL NERVOUS SYSTEM

Besides being a metabolite of nucleotides like ATP, adenosine is a mediator of neuronal function in the central nervous system. Its actions are mediated by at least three extracellular receptors. In this review different aspects of adenosine such as biosynthesis, release, inactivation and its receptors are discussed. It also covers pre- and postsynaptic effects as well as postreceptor mecha...

P124: Listeriosis in Central Nervous System

Listeriosis is one of the CNS inflammatory diseases which is happened majority in the form of sporadic. Listeriosis is ingested with the food. Infection occurrence in an exposed person depends on the number of organisms ingested, the virulence of the organisms strain and the individual condition. It is known that Listeriosis has decisive importance as an infection which the cellular immunodefen...
