Fig. 5: Social observer auditory cortex encodes demonstrator behavioral cues.

a Social observer mean induced power fluctuations in response to Hit trials during early exposure (left), late exposure (middle), and practice (right, only practice sessions with d′ > 1.5 were included). Traces are aligned with demonstrator nose-poke (green bar) and demonstrator reward delivery (purple bar). Induced power (i.e., oscillatory activity not necessarily time-locked to the AM signals) is shown for 2 frequency bands: 6–20 Hz (thick lines) and 20–80 Hz (thin lines). b Non-social exposure animal mean induced power fluctuations in response to Hit trials during early exposure (left), late exposure (middle), and practice (right). For social observers, there was a significant increase in induced power during the demonstrator nose-poke for late exposure and practice sessions (corrected two sample t-tests for individual animals; see Supplementary Table 1). However, these increases in induced power were only observed during practice for non-social exposure animals. For social observers, there was also a significant dip in induced power during reward delivery for early exposure, late exposure, and practice sessions. However, this decrease in induced power was only observed during practice for non-social exposure animals.
