Paper Abstract

We used a four-channel intensity-modulated near-infrared spectroscopy device to study the hemodynamic responses due to brain activation in adults and neonates. The stimuli included finger tapping, tickling of the heel, and auditory stimuli. The subjects included two adults and ten neonates of age between 0.5 and 4 days. A block paradigm was used in the studies, and responses were successfully obtained from both subject groups.
