★ ★ ★ ★ ★

The potential of near infrared spectroscopy (NIRS) in functional studies of the brain has been the focus of many investigations in the last few years [1-4]. The advantage of NIRS towards fMRI is the higher time resolution (a few tenths of ms in NIRS, towards about 1-2 sec in fMRI) and the high sensitivity to the
