For the nervous system to function, neurons must be able to send and receive signals. These signals are possible because each neuron has a charged cellular membrane (a voltage difference between the inside and the outside), and the charge of this membrane can change in response to neurotransmit...
Planes that were hit in the engine never returned. However, data analysis without human abstraction doesn’t reveal this causality. The brain: A force to be reckoned with The third reason complicating AGI is that transistors and neurons are not born equal. Equating intelligence to computing power...

How much memory does the human brain have? Human Brain: The human brain makes up only about two percent of a person's body weight. On average, adult humans' brains weigh a little over three pounds. This makes our brain the largest brain, relative to body size, of any vertebrate animal...
Human Hippocampal Neurons Predict How Well Word Pairs Will Be Remembered. Neuron 30, 289- 298, (2001).Cameron, K. A., Yashar, S., Wilson, C. L. & Fried, I. 2001 Human hippocampal neurons predict how well word pairs will be remembered. Neuron 30, 289-298....
During interactions between neurons, serotonin is released from the end of the first (presynaptic) neuron and picked up by the second (postsynaptic) neuron. Not all of the serotonin will be taken into the second neuron. The remainder, along with what's released from the postsynaptic neuron afte...
The human nervous system ©HowStuffWorks.com Every animal you can think of -- mammals, birds, reptiles, fish, amphibians -- has a brain. But the human brain is unique. Although it's not the largest, it gives us the power to speak, imagine and problem solve. It is truly an amazing...
It also drove home for Lowell just how much we still have to learn. “Sure, we managed to have the brain say ‘Go eat,’” he says. “But that’s not really an explanation. How does that actuallywork?” To answer that question, Lowell has teamed up with Mark Andermann, a neuroscien...
Theneural networkwas widely recognized at the time of its invention as a major breakthrough in the field. Taking inspiration from the interconnected networks of neurons in the human brain, the architecture introduced an algorithm that enabled computers to fine-tune their decision-making -- in other...
In our newly published research in the journalScience, we have identified some of the"rules" the brain uses to learn. Learning in the brain The human brain is made up ofbillions of nerve cells. These neurons conduct electrical pulses that carry information, much like how computers use binary...
