We studied cerebral hemodynamic response to a sequential motor task in 56 subjects to investigate the time course and distribution of blood oxygenation changes as monitored by near-infrared spectroscopy (NIRS). To address whether response is modulated by different performance velocities, a group of subjects (n = 12) was examined while performing the motor(More)
The influence of different lengths of the pre-stimulation resting period on the magnitude of a hemodynamic response evoked by motor stimulation was examined in 10 subjects by means of near-infrared spectroscopy (NIRS). A motor stimulus was used which has been previously established as a model for functional activation studies with NIRS. Subjects performed a(More)
Six patients who had suffered small cerebral ischemia affecting subcortical gray matter were examined with diffusion weighted imaging (DWI) and T2-weighted imaging within the first 8 h, during the next 2 days and after 5-16 days. Areas of apparent diffusion coefficient (ADC) decreases were observed acutely and reached the maximum size during the subsequent(More)
