Figure 2.
The stimulus-evoked LFP decreased with repeated presentations of a stimulus. The data in (A) show an example from a single site (1st–3rd: n = 25 trials, 4th and 5th: n = 22 trials); whereas those in (B,C) show population-level stimulus-evoked LFP. In (A,B), the data illustrate the effect that repeated presentations of the coo vocalization had on the LFP. The data in the first column illustrate the LFPs from the first vocalization presentation. The data in the rightmost column illustrates the LFPs from the fourth and fifth vocalization presentations; the data from fourth and fifth presentations were combined. The gray error bars are bootstrapped 95% confidence intervals of mean. The data in (C) illustrate how the stimulus-evoked LFP decreased as a function of stimulus presentation. The data in each column were generated with a different vocalization: coo (left; n = 77 sites), grunt (middle; n = 63 sites), and scream (right; n = 65 sites). Within each plot, the stimulus-evoked LFP are plotted as a function of stimulus presentation. All of the data are aligned relative to vocalization onset (i.e., the vertical dotted line at time t = 0). The second dotted line indicates vocalization offset.
