Memory: physical, chemical and electrical changes that occur within our brains when we process a memory. The search to identify the biological functions underpinning memory (i. e. , "the biological bases of memory") began with the work of karl lashley over 100 years ago. -studied the brains of animals in his search for evidence that memories are physical. Search for the engram: the physical location of a memory in the brain. -james v. mcconnell and memory transfer in planarians (flatworms) -lashley(1929)- cortical lesions in rats--not matter where lesions were made and how large, traces of maze learning remained--memories are not necessarily stored in a particular area of the brain, but distributed. -memories are not restricted to a particular area of the brain as traces of memory for the maze task remained even after brain tissue was damaged in different brain regions and to varying degrees.
