System and method for optode and electrode positioning cap for electroencephalography, diffuse optical imaging, and functional neuroimaging

摘要

An electroencephalographic electrode and optode positioning device has the form of a cap suitable for placement on a subject's head. The cap has semirigid telescopic structures that stiffen it to provide accurate electrode and optode spacing, and stability during subject activity. The cap is intended for use in functional neuroimaging and, although its materials are compatible with fMRI, is usable without fMRI to permit study of physically as well as mentally active subjects.
