Reflex Activity and the Central Nervous System

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...

The Effect of Hypothermic States upon Reflex and Central Nervous System Activity *

Deaths from exposure to cold in the United States totalled 287 in 1932, 319 in 1933. Every year many individuals are found in a critical hypothermic state, in which there are changes in the nervous control of the body that characterize the condition and are significant in therapy. Studies have been made of monkeys,5 cats2 6 and guineapigs2 which were anesthetized and placed in a cold environmen...

Pseudocholinesterase activity in the central nervous system.

Why does the central nervous system not regenerate after injury?

A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

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...
