Insoluble Proteins of the Synaptic Plasma Membrane
The presynaptic plasma membrane of a CNS neuron is that part of its limiting membrane that confines the terminal knob or bouton of its axonal process.(l, 2) Within the space defined by this structure are containe...

Carrier-Mediated Transport Processes
In Chapter 20(1) the movement of solutes across biological membranes is treated in relation to processes which do not, in general, involve a chemical interaction between the permeant and the membrane, and which a...

Organization of Extrastriate Visual Areas in the Macaque Monkey
In primates, the regions of cerebral cortex that are specifically visual in function occupy the entire occipital lobe plus substantial portions of the temporal and parietal lobes. The division of the occipital...

Factors That Influence Neural Development in Nematodes
Neurons in nematodes are generated by invariant cell lineages. The lineage history of a cell appears to limit its developmental potential, often to a unique fate. Some cells have multiple potential fates; the ...

Neural Development: Implications for Recovery from Injury
The major question considered here is whether it is possible to reconstitute the cellular components of the vertebrate central nervous system (CNS) after injury. In considering this question we discussed the d...

Evidence for a Carrier Mediated Exchange Diffusion of HCO 3 − Against Cl− at the Interphases of the Central Nervous System
The kinetics of the in vivo CO2 dissociation curve of the brain extracellular fluid (ECF) revealed that as soon as the extracellular PCO2 was increased, there was a marked and instantaneous increase in the extrac...

Investigation of the Ional and Gaseous Exchange in the Brain: Measurement and Modelling
Recent investigations of the mechanisms of ional exchange across the red cell membrane give evidence of different diffusional pathways for cations and anions. The mediation of an electroneutral bicarbonate-chl...

The Nonlinear Kinetics of an Electrodiffusion Membrane
Two approaches that have had a dominant influence on the study of excitability are macroscopic electrodiffusion, based on the Nernst-Planck equation, and the channel approach, based on the phenomenological for...

DNA Analysis of Duchenne and Becker Muscular Dystrophies
The linkage analysis of DNA markers in families segregating for Duchenne muscular dystrophy and Becker muscular dystrophy localizes these mutations to the same region of the human X chromosome at Xp21. Several...

On the Role of Trophic Factors VS. Muscle Activity in the Development of Acetylcholine-Receptor Ion Channels in Rat Endplates
The distribution and the functional properties of the nicotinic acetylcholine receptors (AChR.s) in skeletal muscle depend strongly on the state of development of the muscle fibres. Before the embryonic muscle...

Triggering and Amplification
The molecular events which link photon absorption to membrane conductance changes in photoreceptor cells begin with light activation of rhodopsin. In vertebrates, activated rhodopsin (Rh*) triggers an enzymati...

Hippocampal Involvement in Rabbit Eyeblink Conditioning
A conditioning-specific reduction in the afterhyperpolarization (AHP) response has previously been demonstrated in CA1 pyramidal cells in hippocampal slices from well conditioned rabbits. The present studies c...

Arecoline Induces Theta Rhythm, Reduces Pyramidal Cell Excitability and Moderately Impairs LTP In Vivo
In the urethane anaesthetized rat arecoline, oxotremorine and physostigmine administered intravenously induce theta activity and reduce the population spike amplitude of CA1 pyramidal neurons evoked by stimula...

A Combined Transsylvian-Subtemporal Approach for Management of Tumors Located in the Cavernous Sinus and in Meckel’s Cave
Tumors confined to the cavernous sinus and Meckel’s cave are of different entities and can have a varied clinical presentation [1]. The most common tumors in this area are meningiomas and neurinomas. The exact...

Pharmacology of the Ascaris Nervous System
Nematodes are members of a phylum which has made an important impact on medicine and agrochemistry. Out of a total of some 30 000 species described, about half are parasitic. Their occurrence world-wide is phe...

GABAB Receptor Antagonists: Potential Therapeutic Applications
GABA acts as a modulator at postsynaptic GABAB receptors where it mediates late inhibitory postsynaptic potentials and at presynaptic GABAB receptors where it inhibits the release of several neurotransmitters and...

Chapter
Introduction
The special sensory systems are concentrated in the head. This major “information center” is rich in general sensory receptors (touch, pressure, temperature, pain) by the largest cranial nerve — th\e trigemina...

Materials and Methods
The normal topography, cytoarchitecture and myeloarchitecture of the trigeminal nuclear complex was studied on dense series of transverse and saggital sections through the brain stems of adult humans without a...

Chapter
Results
The trigeminal nuclear complex forms a slender cell column through the entire brain stem. In some sections it might be represented by a single perikaryon (in the mesencephalic nucleus) but the complex extends ...
