Autonomic Testing

During certain activities, elements of the autonomic nervous system can be tested by simultaneously measuring beat-by-beat blood pressure, ECG and end-tidal CO2. These activities include the tilt table test, deep breathing test and the Valsalva maneuver. For example, upright position angles of greater than 30 degrees (on the tilt table) usually activate the sinoaortic baroreflex, which is essential for the maintenance of blood pressure and cerebral perfusion while standing.

fNIRS Imaging Education System

fNIRS Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. fNIRS optical imaging technology measures neural activity and hemodynamic response in the prefrontal cortex. Subjects wear an fNIR sensor (IR light sources […]
