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.
Physical training concentrates on mechanistic goals: training-programs in this area develop specific skills or muscles, often with a view of peaking at a particular time. Some physical training programs focus on raising overall physical fitness. In military use, training means gaining the physical ability to perform and survive in combat, and learning the many skills needed in a time of war.
