Enigma of Slumber

Sleep, a complex array of physiological and behavioural processes, is defined as a reversible behavioural condition of perceptual disentanglement from our surroundings. Sleep psychiatry is a flourishing field of cognitive neuroscience that focuses on myriads of interrelations between sleep remedy and psychiatry. Sleep deprivation studies have established the versatile homeostatic functions of sleep including overt cognitive functioning, learning and memory consolidation. Sleep related problems range from insomnia to Kleine-Levin syndrome. At present, there are many sleep laboratories that are spread over the world and are engrossed in exploring the mysteries of sleep.
