Figure 3. Recording locations and ML/AL tonotopy.

Figure 3

a, Schematic of the ventral auditory pathway. b, Coronal MRI sections of monkey A’s brain at the level of the superior temporal gyrus. The purple squares indicate targeted locations of ML and AL. c, Examples of tuned frequency-response profiles from ML (top) and AL (bottom). Each colored line represents responses from a different neuron. Solid lines indicate mean values; dotted lines indicate s.e.m. d, Reconstructions of ML and AL tonotopy. The preferred frequency of ML neurons increased at more posteriorly located sites, whereas those of AL neurons increased at more anterior locations. The ML-AL border was identified from the location of the frequency-gradient reversal. The solid lines are linear regressions that relate recording location with preferred frequency in ML and AL.
