Karl Lashley's most famous research was an attempt to find the parts of the brain that were responsible for learning and memory traces, a hypothetical structure he called the engram. He trained rats to perform specific tasks (seeking a food reward), then lesioned varying portions of the rats' cortexes, either before or after the animals ...
Karl Spencer Lashley (June 7, 1890 – August 7, 1958) was an American psychologist and behaviorist remembered for his contributions to the study of learning and memory. A Review of General Psychology survey, published in 2002, ranked Lashley as the 61st most cited psychologist of the 20th century.

An engram was believed to be a part of the brain where a specific memory was stored. He continued to use the training/ablation method that Franz had taught him.
Karl Pribram had worked with psychologist Karl Lashley on Lashley's engram experiments, which used lesions to determine the exact location of specific memories in primate brains. [2] Lashley made small lesions in the brains and found that these had little effect on memory.
