Studies of decision-making in the monkey, where activity of single neurons in parietal cortex is recorded, you can see a lot about the time-accuracy trade-off in the monkey's decision, and you can see from the neuron's activity at what point in his accumulation of evidence he makes his decision to make a particular movement.
Mirror neurons make human empathy possible.
If you start responding to every stimulus, then you end up as a nerve gas case, quite literally. Neurons fire at once.
The number of neurons in the brain is very much larger than the number of components in a computer.
In the human mind, the number of possible connections that can be made between neurons greatly exceeds the number of atoms in the universe.
Such a bandwidth! God, who may not have a brain made of neurons, or a CPU made of silicon, but if he has the powers attributed to him he must have something far more elaborately and non-randomly constructed than the largest brain or the largest computer we know.
We assume that we have free will and that we make decisions, but we don't. Neurons do. We decide that this sum total driving us is a decision we have made for ourselves. But it is not.
I don't think there's anything unique about human intelligence.
We are all now connected by the Internet, like neurons in a giant brain.
The brain, or cerebrum, is a material entity located inside the skull which may be inspected, touched, weighed, and measured. It is composed of chemicals, enzymes, and humors which may be analyzed. Its structure is characterized by neurons, pathways, and synapses which may be examined directly when they are properly magnified.
Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.
There are billions of neurons in our brains, but what are neurons? Just cells. The brain has no knowledge until connections are made between neurons. All that we know, all that we are, comes from the way our neurons are connected.
You’re nothing but a pack of neurons.
Love is indeed at root the product of the firings of neurons and release of hormones.
The brain immediately confronts us with its great complexity. The human brain weighs only three to four pounds but contains about 100 billion neurons.
I want to travel on a train that smells like snowflakes. I want to sip in cafes that smell like comets. Under the pressure of my step, I want the streets to emit the precise odor of a diamond necklace. I want the newspapers I read to smell like the violins left in pawnshops by weeping hobos on Christmas Eve. I want to carry luggage that reeks of the neurons in Einstein's brain. I want a city's gases to smell like the golden belly hairs of the gods. And when I gaze at a televised picture of the moon, I want to detect, from a distance of 239,000 miles, the aroma of fresh mozzarella.
We are compelled to drive toward total knowledge, right down to the levels of the neuron and the gene. When we have progressed enough to explain ourselves in these mechanistic terms. . . the result might be hard to accept.
There is no scientific theory that could lead us from a detailed map of every single neuron in someone's brain to a conscious experience. We don't even have the beginnings of a theory whose conclusion would be "such a system is conscious.
You probably think Stephen Hawking is in that wheelchair because of a motor neuron disease. But if you got as much barely-legal student poontang as The Hawkster, you'd be in a wheelchair too.
Go pump some neurons. Expand your craniums
