Fig. 8: Neural data reconstruction.
a Coherence map of the original crosstalk-corrupted signals, computed from 3 Hz to 4 kHz for the full recorded response of one implanted device and taking electrode A (top-left electrode of the grid) as reference. LFP and MUA bands are color-coded as red and gray, respectively. b Coherence before and after crosstalk back-correction, taking the first electrode column as a representative set (A, B, C and D). Signals after correction are symbolized by an asterisk (A*, B*, C* and D*). c) Raw signal, high-pass filtered (HPF) signal (fc = 300 Hz) and detected spikes referring to 140 ms s of induced somatosensory evoked activity recorded by electrode A before (black) and after (blue) correction.
