Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin.
The brain is made up of over 100 billion nerve cells with each brain cell connected to around 10,000 other cells, which equals around 1000 trillion connections in your brain. Your brain is actually very soft, jelly-like, and not grey but a deep red in color. The brain controls both involuntary, or lower, actions, such as heart rate, respiration, and digestion. Complex, or higher, mental activity, such as thought, reason, and abstraction, is consciously controlled.
Cerebral Motor Cortex. As the name of the disorder suggests, cerebral palsy affects the cerebrum, the largest portion of the brain. The cerebrum controls voluntary movements, thinking, reasoning and emotions, as well as some specialized functions such as visual processing, speech and hearing.lthough the gray matter processes the information in the brain, the white matter transmits the signals to the rest of the body. Some cerebral palsy occurs due to damage to the white matter, a condition known as periventricular leukomalacia--PVL. The damage in PVL looks like tiny holes in the white matter.
