ah advocate oi tms argument was Karl Lashley, an influential professor of psychology at Harvard during the early 20th century. He tried to find the locus of learning by studying the effects of various brain lesions on the ability of rats to find their way out of a maze. Dr. Lashley found that how badly the learning ability was affected by damage to the brain depended on the extent of damage, not its precise location.
Subsequent studies, however, have shown that the maze experiment wasn’t conclusive because maze learning involves many complex motor and sensory capabilities. Deprived of one capability, an animal can still learn with another. In the late 1950s, Wilder Penfield and ether scientists conducted experiments on human beings as well as animals that dramatically confirmed that all behavior - whether it has to do with learning or emotion - can be traced to specific systems in the brain.
