Somewhere over the brainbow

Science finds it hard to decipher the mysteries of the mind largely because we lack efficient tools. Many people, including many scientists, tend to confuse the mind with the brain, but they are really very different things. The brain is a material network of neurons, synapses, and biochemicals. The mind is a flow of subjective experiences, such as

As my colleague Bruce Perry explains it, the brain is formed in a “use-dependent manner.”5 This is another way of describing neuroplasticity, the relatively recent discovery that neurons that “fire together, wire together.”

A neuron is really good at one thing: summing up the stimulation coming into its dendrites to “decide” whether to fire a pulse along its axon. A neuron by itself isn’t very smart. But if you put neurons together in the right way you get a brain; you get an emergent system that is much smarter and more flexible than a single neuron.

The research teams led by Hines and Keiko Yamasuki had made some progress. They discovered that critical thinking was not produced in any specific location in the cerebral neural network but used a particular mode of nerve impulse transmission, and that with the powerful computer’s assistance, this model could be retrieved and located from among th
