, 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 ...

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.

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 nervous system of Nautilus contains a much larger number of neurons than is found in any noncephalopod mollusk. Many of the neurons lie in peripheral ganglia, especially those of the tentacles and the brachial nerve cords in the arms. On the other hand, there is a great concentration of neurons to form a “brain,” which is composed of cords around ...

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.

Central Nervous System and Computation
The Quarterly Review of Biology, 2011Computational systems are useful in neuroscience in many ways. For instance, they may be used to construct maps of brain structure and activation, or to describe brain processes mathematically. Furthermore, they inspired a powerful theory of brain function, in which the brain is viewed as a system characterized by intrinsic computational activities or ...

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.

Central nervous system (CNS) tumors comprise 15% to 20% of all malignancies occurring in childhood and adolescence. They may present in a myriad of ways, often delaying diagnosis. Symptoms and signs depend on the growth rate of the tumor, its location in the central nervous system (CNS), and the age of the child. This article describes the presentation,

Vasculitis of the Central Nervous System
Seminars in Neurology, 1994Central nervous system (CNS) vasculitis occurs in a variety of clinical settings. Some exhibit a distinct age preference; others a tissue tropism. Most frequently encountered are giant cell arteritis (temporal arteritis) and vasculitis secondary to infections.
