Michio Kaku Quotes

In the brain, you have connections between the neurons called synapses, and they can change. All your knowledge is stored in those synapses.

The human brain is an incredible pattern-matching machine.

We know a certain amount about neurons. You can do fMRI and watch parts of the brain light up. But what happens in the middle is poorly understood.

The brain is such an incredible computer.

When we have any function, whether it's language or vision or cognitive functions like memory, we aren't dealing with a straight line to the brain that says 'This is what I do.' The brain builds a network of connections, a network of neurons that have a particular role in that function.

With its billions of interconnected neurons, whose interactions change from millisecond to millisecond, the human brain is an archetypal complex system.

When I look at the human brain I'm still in awe of it.

All our behaviours are a result of neurophysiological activity in the brain.

The human brain is probably one of the most complex single objects on the face of the earth; I think it is, quite honestly.

The brain is a complex biological organ possessing immense computational capability: it constructs our sensory experience, regulates our thoughts and emotions, and controls our actions.

We have about 100 million cells interconnected in our brains. They communicate with one another through electrical signals.

Everybody agrees that the brain is a remarkable machine. It's capable of generating an enormous number of phenomena, some of them very obvious and some of them less obvious. But I think that in the end there are going to be some very basic explanations for many things: emotions, awareness, consciousness, attention, perception, recognition.

The brain is the most complicated organ in the universe. We have learned a lot about other human organs. We know how the heart pumps and how the kidney does what it does. To a certain degree, we have read the letters of the human genome. But the brain has 100 billion neurons. Each one of those has about 10,000 connections.

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.

In terms of the brain, you can in a crude way think of the human brain as a computer.

The brain is so intricate. It can do so many things, and people sleep on it. It's not just a piece of meat in there - it can do so much.

The human brain is a wonderful organ. It starts to work as soon as you are born and doesn't stop until you get up to deliver a speech.

Neuroscientists talk a lot about brain circuits. In fact, the word 'circuit' is probably misleading. We do not know where most circuits begin and end. And unlike an electrical circuit, brain connections are heavily reciprocal and recursive, so that a direction of information flow can be inferred but sometimes not proven.

The three-pound organ in your skull - with its pink consistency of Jell-o - is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we've dreamt of building.

Everything we do, every thought we've ever had, is produced by the human brain. But exactly how it operates remains one of the biggest unsolved mysteries, and it seems the more we probe its secrets, the more surprises we find.

The amount of sensory material stored up or stored down in the brain's and the body's systems is inestimable. It's like a culture at the bottom of a jar, although it doesn't grow, I think, or help anything else to grow unless you find a way to reach it and touch it.

Our brains have the ability to reorganize themselves by forming new neural connections throughout our lives. This ability is called neuroplasticity.

We cannot experimentally map out the brain. It's just too big. In a piece of the brain the size of a pinhead there are 3,000 pathways like a city with 3,000 streets.

In our skulls, we carry around 3 pounds of slimy, wet, greyish tissue, corrugated like crumpled toilet paper. You wouldn't think, to look at the unappetizing lump, that it was some of the most powerful stuff in the known universe.

When we talk about the brain, it is anything but unidimensional or simplistic or reductionistic.
