Brodmann Areas. Over a lifetime, the various parts of the brain that control the body's movements can suffer damage from various causes, such as head injuries, strokes, and degenerative brain diseases. One typical example is what happens when one side of the motor cortex is completely destroyed by a stroke.ver a lifetime, the various parts of the brain that control the body's movements can suffer damage from various causes, such as head injuries, strokes, and degenerative brain diseases.

Nickel-Metal Hydride battery (Ni-MH or NiMH) The Nickel-Metal Hydride (Ni-MH) battery is a rechargeable power source that is increasingly used in portable computers and other devices. The most advanced rechargeable battery offered, the Ni-MH battery provides up to 40 percent longer service life than Nickel-Cadmium batteries as well as greater charge capacity. Ni-MH batteries are also used in cellular phones and camcorders.
However, the latest AA NiMH batteries provide approximately 75% of the capacity of alkaline AA. batteries at low drain rates and can surpass alkaline performance in high drain applications (i.e. digital. cameras). The true advantage of NiMH batteries can be found in the cycle life (reuse after charging). Typically NiMH. batteries can be recharged hundreds of times, potentially allowing them to be equivalent to hundreds of alkaline. batteries in total service over their lifetime. However, battery life is limited to 5 years or less. This can make. rechargeable NiMH batteries a cost effective power source for many frequently used battery operated devices. found in the home or office.
