The human brain is comparable to the work computer

August 22 2006

In the morning a man opens his eyes and the brain stem sends small amounts of nitric oxide to another part of the brain, the thalamus, which in turn transmits a signal to other cells. As the computer loads the operating system before running more complicated programs, nitric oxide is preparing the ground for more complex operations.

In the first minutes after waking sensory information overloads the system - the bright sunlight coming through the curtains while on the clock - and all this should be handled. Thus, the brain determines the environment and begins to perform more complex tasks. This is the conclusion, scientists from Wake Forest University in North Carolina.

Previously, the thalamus was seen by scientists as rather primitive structure - kind of gate that could either open, allowing the flow of sensory information to the cortex, or disable the flow completely.

A new study has shown that the thalamus acts more like a bouncer at the club, just not allowing a large flow of information to the brain before the brain is ready to receive it, write "more".
