Mass action: rate, efficacy and accuracy of learning depend on the amount of cortex available. The more cortex that is removed, the more learning defects occur –2. WebbThe search for the engram for any learned behavior has been viewed with skepticism by some investigators who quote Karl Lashley: "This series of experiments has yielded a good bit of information about what and where the memory is not. It has discovered nothing directly of the real nature of the engram" (1950, pp. 477-78). great bear winery
