Abstract
The purpose of the study was to use functional near infrared spectroscopy (fNIRS) to explore the extent of activation in occipito-parietal cortices to high-contrast checkerboard stimuli. The distribution of oxyhaemoglobin (HbO), de-oxyhaemoglobin (Hb) and total haemoglobin (THb) concentrations were used as measures of cortical activation. Methods: Data were collected sequentially using the Frequency Domain Multi-Distance (FDMD) oximeter to record absolute chromophore concentration. Responses to three presentation modes: static, pattern-reversal and ON/OFF stimulation, were compared over 15 locations in two participants. The most effective stimulus was used in 10 participants at the most responsive occipito-parietal sites.
