Figure 4

Bubble graph of co-occurrence of responses to macaque vocalizations in neurons that selectively responded to two out of seven macaque calls. The diameter of the circles is proportional to the number of co-occurrences (the scale bubble = 5 co-occurrences). Neurons responded with a higher probability to calls from the same phonetic category, as in the cases of “coo” and “harmonic arch,” which are both harmonic calls, or “bark” and “growl,” which are both noisy calls. Semantic category, does not seem to play a major role at this processing level. Adapted from Tian et al. (2001).
