Nerve-cell function, development

Neurotoxin A toxin that acts by disrupting nerve cell function. Fast-acting neurotoxins often act by blocking the action of an ion gate necessary for the development of an action potential. 

Those with less education may be at greater risk for developing AD. It is unclear why this may be so. One theory is that extensive education may cause nerve cells to produce a more highly branched interconnected communication network. This in turn may provide duplicate backup circuitry in the brain that prolongs normal brain functioning even as brain cells progressively die. 

The synergistic action of aluminum ions with fluoride may be the underlying mechanism of the observed neurotoxic effects of fluoride. Chronic exposure of humans to A1FX begins in the fetus. Elevated fluoride content was found in embryonic brain tissues obtained from required abortions in areas where fluorosis was prevalent [78, 124]. These studies showed poor differentiation of brain nerve cells and delayed brain development. High fluoride exposure appears to weaken mental function among children, as well as adults [125, 126]. 

Every region of the brain is activated and controlled by specific nerve cells. Billions of interconnecting nerve cells orchestrate the complex interactions necessary to carry out a host of functions ranging from basic instincts, reflexes, and life support, such as regulation of blood pressure, to highly developed abilities, such as abstract thought. When all works as it should, people are able to respond to... 

With the development of the human brain, a functional network with over 100 billion interrelated nerve cells and 1010 bit capacity arose. With this system, whose operation is inseparably connected to conscious perception, life on earth reached its most sophisticated form. Furthermore, the human being, who is primarily a social creature, is a building block in the creation of a gigantic product human society. The function and capacity of society obviously exceeds the sum of the activity of its members. Based on the practically inexhaustible capacity of the human brain to acquire drives, human society represents a qualitatively new, higher form of life. For example, a country, presently the most sophisticated form of a human community, consists of millions or even over a billion humans and operates de facto as a huge living complex interacting with other similar entities, about 200 at present. 

With the development of the human brain, a functional network with over 100 billion interrelated nerve cells and 1010 bit capacity arose. With this system, from the operation of which conscious perception is inseparable, life on earth reached its most sophisticated form of appearance. Furthermore, the... 

Only in the last few centuries has the link between the brain and behaviour become clear, and only at the end of the nineteenth century was it demonstrated that the nervous system was made up of billions of separate nerve cells or neurons. We now know that during evolution complex networks of such neurons have developed in order to effect certain behaviours. Whilst the neurons of the central, peripheral and autonomic nervous systems vary enormously in form and function, they can be classed into three broad groups sensory neurons which convey information into the central nervous system effector neurons which carry information out of the central nervous system to muscles and other effector organs and interneurons within the central nervous system which link the sensory and effector neurons and also have links with one another.
