Abstract

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.

First claim

What is claimed is:

1. A positioning cap comprising:
at least one semirigid telescopic structure forming at least one loop, the semirigid telescopic structure capable of extension and compression while maintaining even spacing of devices selected from the group consisting of optodes and electrodes attached thereto;
wherein the semirigid telescopic structures comprise a plurality of telescoping subassemblies, each telescoping subassembly comprising a plurality of links and pivots…
