What was the overall result of Lashley’s research that sought out the engram of human memory?

1: He identified an engram in the frontal lobes of the cerebral cortex.

2: He observed that the engram exists in childhood but disappears when it is no longer needed.

3: He found no evidence that an engram actual exists.

4: He located the engram across the structures of the limbic system.

Answer: 3: He found no evidence that an engram actual exists.

Karl Lashley was one of most pronounced neuropsychologists ever in history who embraced a physiological conception of engram that is a legislation which entails imprinting of specific memory in the brain By using rats or monkeys in set up experiments then, Lashley searched the brain to specifically localize where memory is stored but he did not succeed. In his report, he has argued that examination of human brains has proven that there is no place in our brain where the engram would be localized. Rather than forcing memories to be stored in one place, he postulated that they are connected to many regions of the brain and rely on divergent neuronal networks, opening up the possibility of a distributed memory.
