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.
