Abstract

Haemodynamic changes related to activation of the human visual cortex were studied using optical imaging. The change in oxyhaemoglobin concentration in the visual cortex was estimated using a perturbation Monte Carlo (pMC) method. Comparison to a topographic map obtained using the modified Beer-Lambert law and interpolation is given.
