The human brain has 100 billion neurons, each neuron connected to 10 thousand other neurons. Sitting on your shoulders is the most complicated object in the known universe.

Gorgeous Neuron quotations

There are 100 billion neurons in the adult human brain, and each neuron makes something like 1,000 to 10,000 contacts with other neurons in the brain. Based on this, people have calculated that the number of permutations and combinations of brain activity exceeds the number of elementary particles in the universe.

The brain is a monstrous, beautiful mess.

Its billions of nerve cells - called neurons - lie in a tangled web that displays cognitive powers far exceeding any of the silicon machines we have built to mimic it.

There is no real independent self, aloof from other human beings, inspecting the world, inspecting other people. You are, in fact, connected not just via Facebook and Internet, you're actually quite literally connected by your neurons.

A book can change the world... Every book a child reads creates new neurons in that child's brain.


Go pump some neurons. Expand your craniums

According to materialistic science, any memory requires a material substrate, such as the neuronal network in the brain or the DNA molecules of the genes.

Neurons that fire together wire together.

Consciousness is somehow a by-product of the simultaneous, high frequency firing of neurons in different parts of the brain. It's the meshing of these frequencies that generates consciousness, just as tones from individual instruments produce the rich, complex, & seamless sounds of a symphony orchestra

Your brain has more than 100 billion cells, each connected to at least 20,000 other cells. The possible combinations are greater than the number of molecules in the known universe.


The entire universe - for one thing - only exists in your perceptions.

That's all you're gonna see of it. To all practical intents and purposes this is purely some kind of lightshow that's being put on in the kind of neurons in our brain. The whole of reality.

Today, when we look at a brain, we see an intricate network of billions of neurons in constant, crackling communication, a chemical labyrinth that senses the world outside and within, produces love and sorrow, keeps our hearts beating and lungs breathing, composes our thoughts, and constructs our consciousness.

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.

The brain is a monstrous, beautiful mess.

We sleep, allowing gravity to hold us, allowing Earth - our larger body - to recalibrate our neurons, composting the keen encounters of our waking hours , stirring them back, as dreams, into the sleeping substance of our muscles.


The cells and fibers of the brain must carry some kind of individual identification tags, presumably cytochemical in nature, by which they are distinguished one from another almost, in many regions, to the level of the single neurons.

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.

The number of possible "on-off" patterns of neuronal firing is immense, estimated as a staggering ten times ten one million times (ten to the millionth power). The brain is obviously capable of an imponderably huge variety of activity; the fact that it is often organized and functional is quite an accomplishment!

Emotional states are fairly quick bursts of neuronal gossip.

Traits, on the other hand, are more like the neuronal equivalent of committed relationships.

What do we mean by "knowledge" or "understanding"? And how do billions of neurons achieve them? These are complete mysteries. Admittedly, cognitive neuroscientists are still very vague about the exact meaning of words like "understand," "think," and indeed the word "meaning" itself.


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.

If you meet somebody and are attracted to someone, and the exquisite neurons in your brain and her brain intermesh properly, then things can be wonderful. It's not like homework. You don't have to work at the relationship.

Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.

For me, consciousness is the most interesting unsolved problem of science, and, in fact, we may never know what it is about a particular arrangement of neurons that gives rise to consciousness. Our consciousness, like the air we breathe or like the passage of time, is central to our existence as intelligent beings.

You’re nothing but a pack of neurons.


For the last century of neuroscience, lots of people have tried to control neurons using all sorts of different technologies - pharmacology (drugs), electrical pulses, and so on. But none of these technologies are precise. With optogenetics, we can aim light at a single cell, or a set of cells, and turn just that set of cells on or off.

The newborn infant is now seen to be wired with awesome precision.

.. This marvelous robot will be launched into the world under the care of its parents... But to what extent does the wiring of the neurons, so undeniably encoded in the genes, preordain the directions that social development will follow?

Neurons that fire together wire together.

You can rewire your brain for higher consciousness by focusing on love.

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.

Space and time, not proteins and neurons, hold the answer to the problem of consciousness. When we consider the nerve impulses entering the brain, we realize that they are not woven together automatically, any more than the information is inside a computer.


Thirty years ago I was diagnosed with motor neurone disease, and given two and a half years to live. I have always wondered how they could be so precise about the half.

...an effective psychotherapist or psychoanalyst is a "microsurgeon of the mind" who helps patients make needed alterations in neuronal networks.

In its evolution from a more primitive nervous system, the brain, as an organ with ten or more billion neurons and many more connections between them must have changed and grown as a result of many accidents.

Love is indeed at root the product of the firings of neurons and release of hormones.

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.
