Fig. 5: Informing intraneural decoders with inter-muscular EMG signals.
From: Decoding phantom limb movements from intraneural recordings
A Example of inter-muscular signals filtered between 50 and 350 Hz. B Comparison of the SNN-based decoders’ accuracy in both participants using imEMG, ENG or imEMG + ENG bandwidths. Error bars indicate mean and STD. Chance levels indicated with dashed lines. Two-sided paired t-test, *p < 0.05 (ENG vs. imEMG, p = 0.024 for S1, p = 0.023 for S2. ENG + imEMG vs. ENG, p = 0.06 for S1, p = 0.003 for S2. ENG + imEMG vs. imEMG, p = 0.77 for S1, p = 0.89 for S2). n = 540 for S1 and n = 720 for S2 (5-fold cross validation). Confusion matrix of the SNN signal encoder performance in S1 using the imEMG + ENG bandwidth (50–7.5 kHz).
