Role of Sleep in Memory

Paper Summary:

Evidence gathered from research suggests a strong and positive correlation between sleep and memory consolidation. Based on these research results, this paper argues that it is clear that sleep is not only essential for consolidating what is learnt but also a prerequisite for imbibing new knowledge. A brief outlook into the nature of sleep and memory followed by a review of some of the available research studies provides the reader with a better understanding of the role of sleep in the process of memory.

From the Paper:

"Sleep is an important natural physiological process that consumes almost a third of our lifetime. Many early researches have helped our understanding of the importance of sleep in regulating hormones and other metabolic functions of the body. Researchers have also devoted much attention to understanding the effects of sleep on one of the important functions of the brain, namely memory. Ever since the pioneering research by Jenkins and Dallenbach, which showed positive evidence for the role of sleep in augmenting the memory process researchers have made considerable progress in understanding the process of memory. [C. Smith] Recent Neuroanatomical studies have shed more light on this subject clearly suggesting a positive role of sleep in improving the memory and learning process. In view of these evidences, there are valid reasons to strongly correlate the existing trend of sleep deprivation in the society to the cognitive deficits."
