Motor neurons carry impulses to the effectors in the body, which are the muscles or glands that produce a change based on a stimulus sensed by the receptors. The motor neurons "innervate" muscle fibers, which essentially means that they cause them to move. The fewer the muscle fibers associated with a motor neuron, the more precise are the movements of those fibers. Having to control a small number of fibers, the neuron is able to coordinate more dexterous motions. An example of a region where there are not a lot of muscle fibers related to each neuron is in your fingers.
I think the best phrase to describe this would be Founder effects. Founder effects occurs when a new colony is started by a few members of the original population. This small population size means that the colony may have; a non-random sample of genes in the original population. Reduced variation from the original population.. According to Bottlenecks and founder effects, genetic drift can cause big losses of genetic variation for small populations.

Answer: Experimetal ablation
Explanation: Experimental abaltion
It can be defined as the most common procedure that is used by the scientists in his laboratory. This procedure includes the removal or destruction of a part of brain for studying the functions of the regions of brain.
Then the behavior of the animal is observed to see which part of the brain is responsible for which type of behavior. This can be an unethical practice so it is not used on human beings and is only used in animals.
