Ultrahigh spatial and temporal resolution fMRI with implanted CMOS-based planar microcoil at 14.1T
{Compared to electrophysiological or optical recording of brain activity, fMRI has a rather low spatial and temporal resolution. Here, we propose the use of implanted microcoils for studying animal brain activity in-vivo with ultra high sensitivity compared to conventional coils. A fully integrated CMOS NMR transceiver containing an on-chip-microcoil, integrated amplifiers and a demodulator is used to acquire ultra-localized signal (10nl) at ultrahigh temporal resolution (5ms) showing unprecedented high speeds and spatial resolutions of the BOLD response.}
