While near-infrared spectroscopy (NIRS) has higher temporal resolution than functional MRI and capacity for capturing neural activities even when one performs a single ballistic motor movement, most of studies that measure motor related brain activities with NIRS reported cumulative changes of oxy/de-oxy hemoglobin during a certain periods of a task block(more than a few second). This block design based approach may limit capturing event related neural activities for a single movement. In this paper, we adopted an event related design typically used in fMRI and examined whether it affords to measure reasonable event related change in oxy-hemoglobin when the subjects performs a rapid grasping task. |
