Abstract
Simultaneous investigation of electrophysiology and fMRI in non-human primates presents several challenges on RF coil design. Transmit coil structure should allow access for electrodes from different orientations to allow recordings from different brain regions. Receive arrays must be designed around head posts fixed on the animal head, leading to non-optimum coil orientations in the helmet. In cases with more than one head posts, the receive array must be on two separable halves of the helmet. We developed an RF coil arrangement that optimizes the SNR and provides access for recordings from different regions of the brain.
