How Sleep Helps Memory
There is no longer any doubt. Sleep does improve the gelling or consolidation of memory for recently encoded information. Research is now focusing on how this happens and what other factors interact with the sleep effect. At least two processes seem to be at work: 1) sleep protects new memories from disruption by the interfering experiences that are inevitable during wakefulness, and 2) sleep consolidates memories according to their relative importance and the learner’s expectations for remembering.

Memory Image-mapping Technique for One-try Learning
Are you as smart as a rat? A rat can learn a lot of things with just the first attempt. For example, in the old days, exterminators used to use poisons such as strychnine. What they discovered was that some rats who ate the bait were never killed. If they survived the seizures of the first exposure, they learned not to eat that particular bait again. It’s called “bait shyness.” As a result, exterminators now use a different poison, Warfarin, that does not kill right away. The rat slowly bleeds to death over many days and does not realize any connection between eating that bait and getting sick. The explanation for the difference is illustrated in Figure 1.
