Brain areas affected by sleep deprivation
Lack of sleep can affect individuals in a memory, the ability to do simple daily activities, and attention. Ongoing studies to decipher the basic mechanisms of sleep in the development of drugs that need to sleep in military combat or other circumstances that may help reduce the school. In another study, researchers found that a few hours of sleep a night for impairment of long-term memory and attention. Another study shows that sleep deprivation may actually enhance memory for a short period for certain tasks.Another study gives an overview of what areas of the brain are affected by sleep deprivation and how this impacts on decision-making.Giulio Tononi, MD, PhD, and his group have used a molecular approach to examine what happens during sleep. Have more than 15,000 genes
to identify screened whose expression changes during sleep compared to wakefulness, and also after sleep deprivation. The work of several laboratories in the past year were published that the expression of many genes in Drosophila and mice, changes in the brain at the time of day (eg, 04 am out by 4 clock) dependent. This cycle genes involved after circadian time in many cellular functions work.However, it was not, to what extent changes in gene expression between day and night sleep actually dependent circadian rhythm that when a person is awake or if it was day or night known.Tononi and colleagues have proposed an experiment to determine changes in gene expression associated with sleep and wakefulness in itself, rather than simply day and night. For this purpose, the
electrodes are inserted into the skulls of rats - they are nocturnal animals - to identify their dream and are divided into three groups: rats that were allowed to sleep spontaneously were sacrificed at 18 hours in their usual sleep period, sleep deprivation rats died in the same circadian time, after being kept awake by playing with them for eight hours, spontaneously awake rats were killed at 6 hours during the normal Pages: [1] 2 3 4 5 6
