A Quote by Robert Sapolsky
Show me one neuron that has some cellular semblance of free will. And there is no such neuron.

The well-being of a neuron depends on its ability to communicate with other neurons. Studies have shown that electrical and chemical stimulation from both a neuron's inputs and its targets support vital cellular processes. Neurons unable to connect effectively with other neurons atrophy. Useless, an abandoned neuron will die.
A single neuron in the brain is an incredibly complex machine that even today we don't understand. A single 'neuron' in a neural network is an incredibly simple mathematical function that captures a minuscule fraction of the complexity of a biological neuron.
Here is a neuron that fires when I reach and grab something, but it also fires when I watch Joe reaching and grabbing something. ... It's as though this neuron is adopting the other person's point of view.
There is a neuron in your brain that will respond only to pictures of Jennifer Aniston - provided you have had prior visual exposure to the actress. That neuron does not respond to pictures of Bill Clinton or Halle Berry. Only Jennifer. I used the story to explain the almost ridiculous plasticity of the organ. There is no such thing as Jennifer Aniston in our evolutionary history - she was born in 1969, for heaven's sake - but we are flexible enough to devote an entire cell to her if we have previously encountered her in some fashion.
Synaptic summation is the technical term used in neurophysiology for those instances in which some neuron C is fired only by a combination of neurons A and B.
The doctor who diagnosed me with ALS, or motor neuron disease, told me that it would kill me in two or three years.
Some forms of motor neuron disease are genetically linked, but I have no indication that my kind is. No other member of my family has had it. But I would be in favour of abortion if there was a high risk.
Imagine something a million times more powerful than your smartphone that is the size of a brain cell interfacing with your biological neurons. That will be the complete symbiosis. That will be when we augment our brains at the level of the neuron.
What the ordinary person means by a 'miracle' is some gross distortion or suspension of the laws of nature... but life itself strikes him as commonplace, when in truth a blade of grass or a neuron in the brain is a greater miracle.
The thing about motor neuron disease, once a muscle stops working, it doesn't start again.
If my dramatic career doesn't work out, I will go on to research and find cures for Alzheimer's or Parkinson's and other motor neuron diseases. It's a very exciting field of research. But I'd like to continue in drama, so it wouldn't be very smart of me if I blew this amazing opportunity with an inappropriate lifestyle.
Maybe I don't have the most common kind of motor neuron disease, which usually kills in two or three years.
I don't have much positive to say about motor neuron disease, but it taught me not to pity myself because others were worse off, and to get on with what I still could do. I'm happier now than before I developed the condition.
Your brain has a trillion neurons and every neuron has ten thousand little dendrites. The system of inter-communication is awe-inspiring.
Living in stressful situations there are chemicals in your brain that are released that essentially degrade the neuron connections that allow you to function as a normal human being.
I'm interested in the ideas that sound a little crazy, such as radical life extension, curing cancer, being able to create a simulation of the human brain and map every neuron.
