Figure 2.

(A) Representative electrode track through the left and right red nucleus in monkey E. Diamonds represent where electrical stimulation evoked upper body movements (indicative of red nucleus), squares represent responses to auditory stimulation, and triangles represent locations where no responses to electrical stimulation were observed. (B) Frequency of sites where electrical stimulation evoked upper body movement for all electrode tracks (diamonds monkey E, triangles monkey W) and frequency of unresponsive sites (circles). (C) Probability of sites with electrical evoked upper body movements (diamonds monkey E, triangles monkey W). (D) Probability of sites with auditory responses (diamonds monkey E, triangles monkey W). (E) Category and frequency of the main body movements evoked by the electrical stimulation of the left and right RN (monkeys E and W combined). A, arm; S, shoulder; F, face; M, mouth; E, eye (left nucleus: circles, right nucleus: triangles).
