Small amounts of sleep loss may have profound academic consequences to school-aged children. Unfortunately, there is limited brain research investigating the impact of sleep loss on cognitive areas such as attention. In an effort to address this gap, event-related potentials (ERPs) were recorded during an auditory “oddball” task. Baseline sleep measures were obtained for 78 children, 5-8 years of age, for the first week. In week two, children were randomly assigned to continue normal sleep patterns (control) or restrict sleep for 1 hour each night (restricted). Sleep restriction ERPs for left temporal electrode sites significantly increased in latency and amplitude for the P3 waveform. Increased P3 may indicate modest sleep loss alters brain activity in school-aged children and negatively impacts academic performance.
