Brain research has shown that learning is a means of formation of memory, that is
growing new connections or strengthening existing connections between neurons to
form neural networks. Over the years scientists have studied animals to see what parts
of the brain are related to memory. Usually rats are taught to run a maze and then a
technique of lesioning is used (cutting off parts of brains) to see if the memory has
remained. This obviously can't be done on humans, but researchers can use people
already with brain damage as case studies.
