Approaches to TMS-fNIRS and TMS-EROS montages illustrated with a circular coil. In a coil-bounding montage (A), optodes are arranges around inner and outer edges of a TMS coil. A low-profile approach (B) positions optodes directly beneath the coil by redirecting light with prisms or bending the tips of fiber optics (C).
