The BRAIN is a very important organ of the body that is considered the control center of the nervous system. The brain is very complex that has over 100 billion neurons each connected to thousands of neurons.

Electric stimulation is the basis of neural control that is done by several neurotransmitters such as dopamine, seratonin and others. Hormones are thus produced and often dependant in memory and stimuli.

Blood-brain barrier refers to a barrier that allows only blood, oxygen and specific enzymes to pass to the brain. It protects the brain against many toxins. Blood flow to the brain is extremely vital.

Cerebrospinal fluid circulates in the meninges, the connective tissue that surrounds the brain. It acts to buoy the brain in its cavity and helps as a shock absorber. 

The brain is amazing at taking input from the senses and incorporating it into a recognizable process. Sensory input includes: vision, touch, auditory, taste, and smell.

The brain also receives signals through the nervous system in control and as a responsive to stimuli. 

The brain, cortex, cerebellum and ganglia largely control movement. The control of movement is passed through the brain into the spinal column and back to the specific area of movement.

Fine muscular control is therefore largely dependant on a specific brain activity control.

Behavior and Memory is associated with brain mechanics and neuron control. Much of our understanding is somewhat limited. However mental performance and behavior control can be assessed with neurological science.
