The Analysis of Brain States in Sleep Transition and the Adaptive Control of Sleep Transition

Objective We analysed the states of brain in sleep transition by using adaptive external intervention stimuli.On this basis,we controlled the harmful cognitive activity of sleepers and shortened their sleep latency by changing stimuli.Methods Giving adaptive external intervention stimuli to 15 good sleeps/insomnias,and then we got the amount of behavioral response of these subjects in sleep behavioral response test.Results In the normal sleepers group,all of the ten good sleepers lost their perception of external stimuli and their responsiveness in the test,and they all believe that they had fell asleep in the test subjectively.The normal sleep latency of these good sleeps were at about 20 minutes,but they all had been shortened at about 11 minutes.In the insomnia group,the normal sleep latency of three mild insomnias were all above 30 minutes,but they were shortened in 20 minutes in the sleep test;The normal sleep latency of the other two severe insomnias were at about 120 minutes,one fell asleep in 50 minutes in the sleep test,but the other one did not fall asleep in the sleep test.Conclusion It is useful to shorten sleep latency of these subjects by using adaptive external intervention stimuli.The portable sleep machine is easy to operate and very reliable.We can use it without awakening and obstruction.
