Several different types of tumors, benign and malignant, have been identified in the central nervous system (CNS). The prognoses for these tumors are related to several factors, such as the age of the patient and the location and histology of the tumor.

In this chapter we examine the nervous system and see how the concepts of action potentials and their propagation come together to regulate the body and provide for conscious and voluntary action. We will see that through the summation of many action potentials we can achieve the complexity of computing seen of the brain.

FDG-PET imaging has a defined role in the management of primary brain tumors. In contrast to other tumors, the primary role of FDG-PET imaging is to identify high-grade tumor. This task is complicated by the high background glucose metabolism present in normal cerebral cortex and gray matter structures.

, 1981 A knowledge of the development and maturation of the brain is essential for the understanding of anatomical malformations and the possible effects of environmental processes on the brain in late fetal and early neonatal life. Integration of the variables of organogenesis, histogenesis, myelination, and vascular formation is complex, as are the ...

The plant kingdom is replete with compounds and mixtures of compounds that have a stimulating or calmative effect on the central nervous system (CNS). In cases where this action is due to a single high-potency compound that can be chemically isolated, such as morphine, cocaine, or atropine, the plant and its preparations are considered to be outside ...

SCC is uncommon in children. Consequently, there is a paucity in the data concerning SCC in children; however, it has been reported to occur in 2.7–5% of children with cancer and in 4% of children at diagnosis of cancer (Kelly and Lange 1997).

OSMORECEPTORS IN THE CENTRAL NERVOUS SYSTEM
Annual Review of Physiology, 1997▪ Abstract Osmoreceptors regulate sodium and water balance in a manner that maintains the osmotic pressure of the extracellular fluid (ECF) near an ideal set point. In rats, the concerted release of oxytocin and vasopressin, which is determined by the firing rate of magnocellular neurosecretory cells (MNCs), plays a key role in osmoregulation through

The central nervous system (CNS) in relation to dentistry is the topic of this chapter. Nerve conduction is described, then the physiology of facial and dental pain and processing of afferent pain nerve impulses in the cerebral cortex. We discuss abnormal sensations of allodynia and paraesthesia.

Purinoceptors in the central nervous system
Drug Development Research, 1996New exciting developments on the occurrence and functional role of purinoceptors in mammalian brain were presented at the session "Purinoceptors in the central nervous system" chaired by Flaminio Cattabeni and Tom Dunwiddie at the Purines '96 international conference.
