A Quote by David Eagleman
All activity in the brain is driven by other activity in the brain, in a vastly complex, interconnected network.

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.
Abnormalities in brain function have traditionally been detected using electroencephalography (EEG), which involves the measurement of the ongoing electrical activity generated by the brain.
The structure of the human brain is enormously complex. It contains about 10 billion nerve cells (neurons), which are interlinked in a vast network through 1,000 billion junctions (synapses). The whole brain can be divided into subsections, or sub-networks, which communicate with each other in a network fashion. All this results in intricate patterns of intertwined webs, networks of nesting within larger networks.
The brain of a person in love will show activity in the amygdala, which is associated with gut feelings, and in the nucleus accumbens, an area associated with rewarding stimuli that tends to be active in drug abusers. Or, to recap: the brain of a person in love doesn't look like the brain of someone overcome by deep emotion. It looks like the brain of a person who's been snorting coke.
Be aware of the big difference between inspired action and activity. Activity comes from the brain-mind and is rooted in disbelief and lack of faith - you are taking action to “make” your desire happen. Inspired action is allowing the law to work through you and to move you.
Activity feels hard. Inspired action feels wonderful.
The brain is not the mind. It is probably impossible to look at a map of brain activity and predict or even understand the emotions, reactions, hopes and desires of the mind.
We will move from looking at correlations between brain activity and behaviour to studying how the brain causes mental states and behaviour.
Art and writing come from somewhere down around the lizard brain. It's a much more peculiar activity than we like to think it is. The problems arise when we try to domesticate the practice, to pretend that it's a normal human activity and that "everybody's creative." They're not.
Scientists who study brain-wave activity found that the longer one watches television, the more likely the brain will slip into "alpha" level: a slow, steady brain-wave pattern in which the mind is in its most receptive mode. It is noncoggnitive mode; i.e., information can be placed into the mind directly, without viewer participation.
With any hallucinations, if you can do functional brain imagery while they're going on, you will find that the parts of the brain usually involved in seeing or hearing - in perception - have become super active by themselves. And this is an autonomous activity; this does not happen with imagination.

The animal is one with its life activity. It does not distinguish the activity from itself. It is its activity. But man makes hislife activity itself an object of his will and consciousness. He has a conscious life activity. It is not a determination with which he is completely identified.
The objective psychologist, hoping to get at the physiological side of behavior, is apt to plunge immediately into neurology trying to correlate brain activity with modes of experience ... The result in many cases only accentuates the gap between the total experience as studied by the psychologist and neural activity as analyzed by the neurologist.
Since functional brain imaging first emerged, we have learned that there aren't very many brain regions uniquely responsible for specific tasks; most complex tasks engage many if not all of the brain's major networks. So it is fairly hard to make general psychological inferences just from brain data.
Activity and rest are two vital aspects of life. To find a balance in them is a skill in itself. Wisdom is knowing when to have rest, when to have activity, and how much of each to have. Finding them in each other - activity in rest and rest in activity - is the ultimate freedom.
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.
