Article Title: Neuroimaging to detect cortical projection of vestibular response to caloric stimulation in young and older adults using functional near-infrared spectroscopy (fNIRS)

doi: 10.1016/j.neuroimage.2013.02.061

Figure Lengend Snippet: Brain regions that are known to be involved in the response to unilateral caloric vestibular stimulation are shown above (images were generated using the T2T java applet (Deppe et al. 2003)). Regions such as the superior temporal gyrus (STG), prefrontal cortex (PFC), and supramarginal gyrus (SMG) are all accessible to fNIRS as indicated by the color bar that indicates depth. These regions have been projected to the cortical surface of the Colin-27 brain. Yellow dots indicate the region of the bilateral fNIRS probe used in this study.

Article Snippet: Although deeper areas of insula, thalamus, anterior cingulate and putamen would also be found to be activated during caloric activation, these areas are too deep inside the brain for fNIRS measurements, which are limited to about the first 5–8 mm of the cortical surface. summarizes the cortical regions that have been identified from previous fMRI and PET studies, which are expected to be accessible to fNIRS imaging. fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window caption a7 Brain regions that are known to be involved in the response to unilateral caloric vestibular stimulation are shown above (images were generated using the T2T java applet ( Deppe et al. 2003 )).
