The Brain During Deep Sleep

08/28/2006 4:47 PM

Researchers have determined that during the deepest part of sleep, the mind acts like individually working sections. When we are awake, the brain behaves more like a network, with different sections connected by synapses.

The researchers used a magnetic field to generate an impulse in the brain and then studied how that perturbation traveled throughout the brain. They found that while awake, the signal would travel around the brain relatively easily. However during deep sleep, they found the signal died very quickly. The researches believes this means the brain is more compartmentalized during sleep.

Brain and Sleep

08/30/2006 11:14 PM

Brain perhaps has many states that are self controlled capabilities of returning from one to another. Brain interacts with external work more actively only when we are awake. However, brain activity is an endless process like our heart activity which keeps us living even though it is regulated on demand. Brain actually knows what it wants to do with itself. Hence, there need to be hidden brain to take care of this. Or one can say there are many brains in one and at times they cooperate to help some supper brain, who may be called the master brain. Consciousness of 38.2Hz was observed by the brain in meditation. Even though this figure may not be exact, the cycle is rather slow one and very complex. Brain with zero response to external world likely to be in the over crowded traffic state, where nothing moves properly. Only stable resolved states permit conclusive decision or result into an idea of consciousness for others. Brain may be conscious in COMA for itself and confused for external world.

Some researcher may be badly confused that brain cells are single moto pulsers or oscillators or functional states of action. They all have genetic material and perhaps are better quantum mechanically designed machines. Billions of brains work alike, hence, it is somewhat very stable design even though may have different efficiencies. Learning is like storing food for next day. Brain's food has this extra requirement called knowledge. Evolution is also the same thing.
