We investigated slow spontaneous oscillations in cerebral oxygenation in the human adult's
visual cortex. The rationale was (1) to demonstrate their detectability by near infrared …

Changes in optical properties of biological tissue can be examined by near-infrared
spectroscopy (NIRS). The relative transparency of tissues including the skull to near-infrared …

There is evidence that repetitive transcranial magnetic stimulation (rTMS) applied to the
prefrontal cortex has antidepressive properties. In the present study we evaluated the …

Background and Purpose—With increasing age, assuming the upright position is more often
accompanied by symptoms such as dizziness and lightheadedness, possibly as a result of a …

Near-infrared spectroscopy (NIRS) is a noninvasive technique for continuous monitoring of
the amounts of total hemoglobin (total-Hb), oxygenated hemoglobin,(oxy-Hb) and …

Previous imaging studies have shown that cerebral metabolism is gradually reduced at the
beginning of sleep. Few studies have examined the sleep state transition periods from …

Near infrared spectroscopy has recently been used to measure changes of optical
parameters (ie, light absorption or scattering) of brain tissue. The fact that the equipment is …

There are a number of applications in which it is useful to simultaneously collect data from
what are traditionally separate instrumentation modalities. In particular, in vivo physiological …
