Baylor College of Medicine is recruiting boys between the ages of 4 and 9 years for a study on sleep patterns and melatonin in children with and without autism.

Volunteers will be asked to wear an actigraph, similar to a wristwatch, for one week to measure their activity. An overnight stay at Texas Children’s Hospital also will be required.

Volunteers will be compensated for their time. For more information, contact Aryn Knight at 832-822-3751 or
