The Brain

The brain is an organic system which stores and processes sensory and genetic information.

Stimulation of the brain produces neurochemical impulses which trigger on-off signal responses.

The fastest reaction times in the human brain occur during the negative ‘off’ state of a brain wave, and the slowest reaction times occur during the ‘on’ state.

The minimum duration for processing a sensation in the brain is about one-eleventh of a second.

When a brain cell, or neuron, is in the ‘on’ state, a wave impulse travels along the nerve fiber to its end, where it releases a chemical known as a neurotransmitter. The neurotransmitter travels across a synapse, or tiny gap, to another nerve fiber, which in turn causes a new signal to fire. This pattern of firing continues until a particular circuit is complete within the brain.

The chemical process which occurs at the synapse dramatically slows down the transfer of information, and is responsible for the delayed time reactions in our thinking and motor response.

There are oscillating patterns in the brain which directly correspond to functional states. Cells in the thalamus which vibrate at 2 cycles per second reflect a state of deep sleep. At 10 cycles per second, the brain is awake, but not paying attention to the outside world. And at 40 cycles per second, the brain is either wide awake, or actively dreaming.

Acceleration rates in the sensory and motor activities of the human nervous system correspond to an increase in stimulation, which can occur without a corresponding increase in information processing. Conversely, when the rate of brain impulses increases, but there is no increase in normal sensory or motor stimulation, the rate of information processing is increased.

When an increased rate of stimulation without a corresponding increase in processing is synchronized with rhythmic fluctuations in the metabolic rate, heartbeat, breathing, vasomotor tone, and body temperature, radical fluctuations are caused throughout the body. These include an increase in cerebral vigilance, a subjective experience of objects, the loss of the sense of time, time contraction, space expansion, and an increased response to sensory stimulation.
