Memory is measured by a task in which the experimenter interacts with a toy and the measure of memory is whether the child imitates that action when given the toy. Sleep is assessed with a watch that detects motion which provides an estimate of sleep and a set of electrodes placed on the head that measures brain activity during sleep. Infants are recruited at 9 months and sleep and memory are measured again 3- and 6-months later. At each visit, memory is tested before and after a nap (either the morning or afternoon nap) and naps are recorded with the sleep electrodes.",[72],"Sleep Deprivation","2024-05-06",{"date":75,"type":76},"2024-05-08","ACTUAL",{"date":78,"type":76},"2023-09-01",{"date":80,"type":66},"2029-01-31",{"name":5,"class":6},1]
