Brains don't really smell, but what's amazing about the brain is that it's almost like scrambled eggs or soft tofu, almost like a gel. The brain controls so much of what we do, but you could put your finger right through it.
Neuron
He was the first scientist to use the word “neuron”.
Perhaps of all the most basic elements of music, rhythm most directly affects our central nervous system.
Viagra does have a physiological effect, but it doesn't make women feel aroused. Nowadays, researchers are looking at drugs that affect the central nervous system rather than blood flow to the genitals.
The most venomous animal that lives in the ocean is the box jellyfish. And every one of those barbs is sending that venom into this central nervous system. So first I feel like boiling hot oil I've been dipped in. And I'm yelling out, 'Fire! Fire! Fire! Fire! Help me! Somebody help me!' And the next thing is paralysis.
The chief function of the body is to carry the brain around.
Heads are a good deal, and I think they would be a common feature. It's hard to think of species that don't have heads, although there are some. It's good to have a head because it puts some of the sensory organs - eyes, ears, whiskers or whatever - next to the CPU, the brain.
In my view, while the single neuron is the basic anatomical and information processing-signaling unit of the brain, it is not capable of generating behaviors and, ultimately, thinking. Instead, the true functional unit of the central nervous system is a population of neurons, or neural ensembles or cell assemblies.
Dementia is, after all, a symptom of organic brain damage. It is a condition, a disorder of the central nervous system, brought about in my case by a viral assault on brain tissue. When the assault wiped out certain intellectual processes, it also affected emotional processes.
It is the brain, not the heart or lungs, that is the critical organ.
The fact that three-fifths of an octopus' neurons are not in their brain, but in their arms, suggests that each arm has a mind of its own.
Why do we have a brain in the first place? Not to write books, articles, or plays; not to do science or play music. Brains develop because they are an expedient way of managing life in a body.
Further study of central nervous action, however, finds central inhibition too extensive and ubiquitous to make it likely that it is confined solely to the taxis of antagonistic muscles.
All this sensory input, which begins in the brain, has its effect throughout the body.
There's a lot of neuroscience now raising the question, 'Is all the intelligence in the human body in the brain?', and they're finding out that, no, it's not like that. The body has intelligence itself, and we're much more of an organic creature in that way.
With the arrival of electric technology, man extended, or set outside himself, a live model of the central nervous system itself. To the degree that this is so, it is a development that suggests a desperate and suicidal autoamputation, as if the central nervous system could no longer depend on the physical organs to be protective buffers against the slings and arrows of outrageous mechanism.
The computer is the most extraordinary of man's technological clothing; it's an extension of our central nervous system. Beside it, the wheel is a mere hula-hoop.
Octopuses have hundreds of suckers, each one equipped with its own ganglion with thousands of neurons. These 'mini-brains' are interconnected, making for a widely distributed nervous system. That is why a severed octopus arm may crawl on its own and even pick up food.
Although it's the hub of the nervous system and the ultimate terminus of every nerve, the brain itself lacks enervation and therefore cannot feel pain.
The abdominal and waist region coordinate all parts of the body and act as the center or generator. Therefore, you can promote the ability to control the body's action and master your will more easily.
It's not telepathy. It's not the Borg. But we created a new central nervous system made of two brains.
I have strong views against substance usage and abuse. It's bad for kidney and central neuro system.
Anyone who doubts that caffeine is a drug should read some of the prose composed under its influence.
The brain is the highest of the organs in position, and it is protected by the vault of the head; it has no flesh or blood or refuse. It is the citadel of sense-perception.
When it comes to having a central nervous system, and the ability to feel pain, hunger, and thirst, a rat is a pig is a dog is a boy.
