Figure 2.
Structural and functional specializations across the tonotopic axis of nucleus magnocellularis (NM). (A, B, and D) Schematic illustrations showing the structural (A), synaptic (B), and tuning (D) differences between mid- to high-frequency NM and low-frequency NM (termed NMc) neurons. Structural and synaptic differences were modified from Wang et al.19 Tuning differences were modified from Warchol and Dallos.17,19 (C) Schematic illustrations showing the tonotopic orientation of NM. Tonotopic orientation was modified from Kuba and Ohmori.21 For simplicity, “NM” in all figures represents the traditionally defined, adendritic NM neurons that are mainly located in mid- to high-frequency region.
