Mode of Presentation/Audience: Journal / Audience already familiar with anatomy

Objective: To illustrate one of the neurological experiments conducted on STS-90, the "Neurolab" mission of the space shuttle Columbia. Studies were made of sleep, balance, blood pressure control, sensory integration & navigation, and developmental changes in weightlessness. A sagittal view of the brain's venous circulation, suprachiasmatic nucleus, and pineal body is used to orient the viewer to anatomical structures involved in the release of melatonin into circulation. The second figure shows the position of the sleepnet headgear, which measured airflow and brain activity during sleep periods, on a "sleepy" astronaut. The two sagittal views of the airway illustrate a case where sleep apnea occurs in earth's gravity (1G) but does not occur in weightlessness (0G).
