Speeded near infrared spectroscopy (NIRS) response detection. [PDF]
PLoS ONE, 2010 The hemodynamic response measured by Near Infrared Spectroscopy (NIRS) is temporally delayed from the onset of the underlying neural activity. As a consequence, NIRS based brain-computer-interfaces (BCIs) and neurofeedback learning systems, may have a ...

Monitoring Detrusor Oxygenation and Hemodynamics Noninvasively during Dysfunctional Voiding
Advances in Urology, 2012 The current literature indicates that lower urinary tract symptoms (LUTSs) related to benign prostatic hyperplasia (BPH) have a heterogeneous pathophysiology. Pressure flow studies (UDSs) remain the gold standard evaluation methodology for such patients.
