Phase coherence between LFP and natural scenes as a function of both spectral and temporal modulation frequency. A, Phase coherence between the LFP and narrowband envelopes of a savanna acoustic scene for a single cortical site as a function of both spectral and temporal frequency bands. x-axes depict frequency in hertz; y-axes depict spectral frequency in kilohertz. Color bar denotes phase coherence. B, Another example of a cortical site showing robust phase coherence in the 5–10 kHz band and for multiple temporal modulation frequencies. Figure conventions as in A. C, Percentage of cortical sites that showed enhanced phase coherence between savanna scenes and LFP as a function of both spectral and temporal frequency. x-axes depict temporal frequency in hertz; y-axes depict spectral frequency in kilohertz. Color bar denotes percentage of sites. For the same analysis for other acoustic scenes, see supplemental Figure S6 (available at www.jneurosci.org as supplemental material).
