1 Perhaps the most important distinction is between neurons with and neurons without long axons. 2  The long-axoned cells, called principal neurons, transmit information over long distances from one brain region to another (Sheperd,1979). 3  Principal neurons provide the pathways of communication within the nervous system.
Training is the process of being conditioned or taught to do something, or is the process of learning and being conditioned. When you teach a new employee how the business works, this is an example of training.
Teachers must get a college education and pass certification programs. Training the trainer means providing proper preparation for those who train or instruct other people. Many trainers are required to attend continuing education classes on a regular basis in order to learn new techniques and keep skills sharp.
