WebMay 17, 2024 · Optical imaging methods including near-infrared II fluorescence imaging (NIR-II) and two photon microscopy were also used to observe cerebrovascular structure with high resolution ( Sakadžiæ et al., 2010; Hong et al., 2012 ). But most of these methods focus on the cortex because of limited penetration depth. WebSeveral functional brain imaging techniques have been used to study human cortical organization. Optical imaging of intrinsic signals (OIS) offers perhaps the best combination of spatial coverage, resolution and speed for mapping the functional topography of human cortex. In this review, we discuss recent advances in optical imaging technology and …
