Improving Balance Function Using Low Levels of Electrical Stimulation of the Balance Organs

A device based on this technology may be used as a miniature patch worn by people with disabilities to improve posture and locomotion, and to enhance adaptability or skill acquisition. Crewmembers returning from long duration space flight face significant challenges due to the microgravity induced inappropriate adaptations in balance/sensorimotor function. The Neuroscience Laboratory at JSC is developing a method based on stochastic resonance to enhance the brain’s ability to detect signals from the balance organs of the inner ear and use them for rapid improvement in balance skill, especially when combined with balance training exercises. This method involves a stimulus delivery system that is wearable/ portable providing imperceptible electrical stimulation to the balance organs of the human body.

Development of a Low- Cost, Portable Biosensor for Blood Protein Detection

This innovation offers a high level of medical diagnostic sensing abilities comparable to more costly clinical instrumentation. Current blood testing procedures are expensive and time consuming, and the equipment required is often bulky and difficult to transport. A new low-cost, portable technique has been developed to quickly and reliably detect specific proteins in a sample of human blood. The technique, described in the Sept. 1, 2011 issue of the Optical Society’s (OSA) open-access journal, Biomedical Optics Express, could help in a wide range of medical sensing applications, including diagnosing diseases like cancer and diabetes long before clinical symptoms arise.

Mini-Sensor Measures Magnetic Activity in Human Brain

A recent study indicates that the technology may be used in magnetoencephalography (MEG), a noninvasive procedure that could advance the study of neurological diseases. A miniature atom-based magnetic sensor has passed an important research milestone by successfully measuring human brain activity. Experiments verified the sensor's potential for biomedical applications such as studying mental processes and advancing the understanding of neurological diseases.
