Steady state evoked potential (SSEP) responses in the primary and secondary somatosensory cortices of anesthetized cats: Nonlinearity characterized by harmonic and intermodulation frequencies
Fig 4
Exemplar logSNR at f2 = 200Hz depends on the vibration amplitude of F2 = 200Hz.
This figure is shown with the same format as Fig 3. (A) logSNR of bipolar channel 36 in S1 (Session 2–2). This channel’s responses at f2 = 200Hz showed a significant main effect of F2 = 200Hz amplitude, but neither the main effect of F1 = 23Hz nor their interaction. x-axis is the response frequency f, around f = 200Hz. p-value (F1, F2, interaction) = (0.00043, <10−5, 0.14) with the corrected threshold 0.00019. (B) Spatial mapping of logSNR at f2 = 200Hz across all channels in S1 (Session 2–2).
