A Quote by Steven Pinker
The actual organization of behavior goes on the level of the individual nerve cells and their connections, and we have a hundred billion nerve cells, probably a hundred trillion connections. It's just mind-boggling to think of all the different ways in which they're arranged in a baby's head.

With its hundred billion nerve cells, with their hundred trillion interconnections, the human brain is the most complex phenomenon in the known universe - always, of course, excepting the interaction of some six billion such brains and their owners within the socio-technological culture of our planetary ecosystem!
In nerve-free multicellular organisms, the relationships of the cells to each other can only be of a chemical nature. In multicellular organisms with nerve systems, the nerve cells only represent cells like any others, but they have extensions suited to the purpose which they serve, namely the nerves.
You could double the number of synaptic connections in a very simple neurocircuit as a result of experience and learning. The reason for that was that long-term memory alters the expression of genes in nerve cells, which is the cause of the growth of new synaptic connections.
The human brain is estimated to have about a hundred billion nerve cells, two million miles of axons, and a million billion synapses, making it the most complex structure, natural or artificial, on earth.
A single human brain has about a hundred million nerve cells... and a computer program that throws light on the mind/brain problem will have to incorporate the deepest insights of biologists, nerve scientists, psychologists, physiologists, linguists, social scientists, and even philosophers.
The human brain is the last, and greatest, scientific frontier. It is truly an internal cosmos that lies contained within our skulls. The more than 100 billion nerve cells and trillion supporting cells that make up your brain and mine constitute the most elaborate structure in the known universe.
The body and dendrites of a nerve cell are specialized for the reception and integration of information which is conveyed as impulses that are fired from other nerve cells along their axons.
And you are made of a hundred trillion cells. We are, each of us, a multitude.
The task of neural science is to explain behaviour in terms of the activities of the brain. How does the brain marshall its millions of individual nerve cells to produce behaviour, and how are these cells influenced by the environment...? The last frontier of the biological sciences – their ultimate challenge – is to understand the biological basis of consciousness and the mental processes by which we perceive, act, learn, and remember.
The brain is really hard to see. The whole thing is very large - the human brain is several pounds in weight - but the connections between brain cells, known as synapses, are really tiny. They're nanoscale in dimension. So if you want to see how the cells of the brain are connected in networks, you have to see those connections, those synapses.
Odd to think that the piece of you I know best is already dead. The cells on the surface of your skin are thin and flat without the blood vessels or nerve endings. Dead cells, thickest on the palms of your hands and the soles of your feet.
The brain is a tissue. It is a complicated, intricately woven tissue, like nothing else we know of in the universe, but it is composed of cells, as any tissue is. They are, to be sure, highly specialized cells, but they function according to the laws that govern any other cells. Their electrical and chemical signals can be detected, recorded and interpreted and their chemicals can be identified; the connections that constitute the brain's woven feltwork can be mapped. In short, the brain can be studied, just as the kidney can.
The technology involved in making anything invisible is so infinitely complex that nine hundred and ninety-nine billion, nine hundred and ninety-nine million, nine hundred and ninety-nine thousand, nine hundred and ninety-nine times out of a trillion it is much simpler and more effective just to take the thing away and do without it.
The structure of the human brain is enormously complex. It contains about 10 billion nerve cells (neurons), which are interlinked in a vast network through 1,000 billion junctions (synapses). The whole brain can be divided into subsections, or sub-networks, which communicate with each other in a network fashion. All this results in intricate patterns of intertwined webs, networks of nesting within larger networks.
The hunger drive is truly a mind-body connection. Eating is so important that the nerve cells of appetite are located in the hypothalamus region of the brain.
The brain likes to be efficient and so even as its strengthening the pathways you're exercising, it's pulling - it's weakening the connections in other ways between the cells that supported old ways of thinking or working or behaving, or whatever that you're not exercising so much.
