Migratory Reed Warblers Need Intact Trigeminal Nerves to Correct for a 1,000 km Eastward Displacement (original) (raw)
Figure 2
Orientation of birds at the capture and displacement site.
(A, C) Results for sham-sectioned birds, before sham-surgery at the capture site (A) and after sham-surgery and translocation to the displacement site (C). (E, G) Results for V1-sectioned birds before V1-sectioning at the capture site (E) and after V1-sectioning surgery and translocation to the displacement site (G). For description of the circular diagrams and the map (D), see Figure 1. The schemes of real V1-section (F) and sham section (B) show the approximate locations of the three branches of the trigeminal nerve. The ophthalmic branch (V1) is shown in bold. The crosses on F indicate the approximate locations at which the nerve was sectioned and a piece of the nerve was removed. For details about the surgeries, see Methods.
