Steady state evoked potential (SSEP) responses in the primary and secondary somatosensory cortices of anesthetized cats: Nonlinearity characterized by harmonic and intermodulation frequencies
Fig 5
Exemplar logSNR at f1 = 23Hz depend on the vibration amplitude of F1 = 23Hz, F2 = 200Hz, and their interaction.
The same format as Fig 3. (A) logSNR of bipolar channel 158 in S1 (Session 2–2). This channel’s responses at f1 = 23Hz showed a significant main effect of F1 = 23Hz amplitude, the main effect of F2 = 200Hz, and their interaction. x-axis is the response frequency f, around f = 23Hz. p-values (F1, F2, interaction) are all p<10−5 with the corrected threshold 0.00019. (B) Spatial mapping of logSNR at f2 = 200Hz across all channels in S1 (Session 2–2).
