Weboptics-based techniques. The use of optical intrinsic signal imaging (OIS) for intraoperative brain mapping was pioneered by (Haglund et al., 1992) producing functional maps of high temporal resolution but requiring a glass plate to be in contact with the cortex (to minimize movement related artefacts) and several task repetitions to WebWe applied the intrinsic optical imaging technique to the human primary somatosensory cortex during brain tumor/epilepsy surgery for nine patients. The cortical surface was illuminated with a Xenon light through an operating microscope, and the reflected light, which passed through a 605 nm bandpass filter, was detected by a CCD camera-based …

Optical imaging techniques, such as optical intrinsic signal imaging 5 (OIS), have been devel-oped and widely applied to task-based evoked responses. 6,7 Most recently, OIS has been applied with wide field-of-view (FOV) to monitor functional connectivity in cases of disease 8,9
WebOptical Intrinsic Signal imaging (OISi) is a powerful technique for optical brain studies. OIS mainly reflects the hemodynamic response (HR) and metabolism, but it may also involve changes in tissue light scattering (LS) caused by transient cellular swelling in the active tissue. Here, we explored the developmental features of sensory-evoked OIS in the rat …
