Table 4

Mean standardized RS during singing periods with versus without head movements (n = 6 neurons that showed lower RS during head movements that occurred within singing compared with non-singing periods)

Singing w/ headmovements > singing w/out head movements(n = 3/6)Singing w/ headmovements = singing w/out head movements(n =1/6)Singing w/ headmovements < singing w/out head movements(n = 2/6)
Singing w/ movements0.35–0.91 ± 0.700.440.44–2.75
Singing w/out movements0.10–0.36 ± 0.340.240.74–3.88
  • Neurons are categorized by whether RS during singing that included head movements was greater than (left), equal to (middle), or lower than (right) RS during singing that lacked head movements. All responses are significantly different from quiescence. Gray lines in Fig. 5C, right, depict head movement responses.
