BRAIN

At the heart of Llinás's theory is the concept of oscillation.
Many neurons possess electrical activity, manifested as
oscillating variations in the minute voltages across the cell
membrane. On the crests of these oscillations occur larger
electrical events that are the basis for neuron-to-neuron
communication. Like cicadas chirping in unison, a group of
neurons oscillating in phase can resonate with a distant group
of neurons. This simultaneity of neuronal activity is the
neurobiological root of cognition. Although the internal state
that we call the mind is guided by the senses, it is also
generated by the oscillations within the brain. Thus, in a certain
sense, one could say that reality is not all "out there," but is a
kind of virtual reality
