Consciousness For some experts, the mind is the
ultimate exemplar of emergence. Your brain contains several billion neurons
that perform a very simple function: relaying electrical messages across
synapses to their neighbors. It's a physical action, yet out of their
collective firings somehow arises a psychological phenomenon—the
conscious mind. Can consciousness be reduced to the interactions of neurons?
Experts have no way of knowing, because the brain is orders of magnitude more
complex than any computer today, making answering that question at present
difficult if not impossible.
