(a) Differential LFP recordings acquired from the thalamus of an anaesthetised non-human primate with the experimental setup illustrated in Fig. 12. (b) A detailed view of the recorded LFPs reveals their small amplitudes (< 20 μV peak). (c) Amplitude spectrum of the recorded LFPs. Clearly, the proposed instrument can wirelessly provide low-noise recordings of weak LFP signals in a noisy clinical environment
