The premotor cortex is also known as the premotor area and the agranular cortex of Brodmann's area 6. Brodmann's areas are 47 different brain regions located on a map of the brain created by the German anatomist, Korbinian Brodmann.The premotor cortex is so-named because it is located before the primary motor cortex.he premotor cortex has connections with the prefrontal cortex and the supplemental motor area. It also has connections with the spinal cord and helps control movements in the trunk muscles of the body.
Nickel-metal hydride batteries (Ni-MH or NiMH) are similar to Ni-Cd batteries, with the exception that the cadmium in these batteries has been replaced with a hydrogen-absorbing alloy. This provides several advantages over standard Ni-Cd rechargeable batteries.
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.
