Terminal arborizations of 13 types of identified cercal sensory afferents within the terminal ganglion.A, Diagram of a cricket showing the location of the terminal abdominal ganglion and cerci. B, Computer reconstruction of the outline of the terminal ganglion showing afferent type #1 as an example, dorsal view. Thevertical and horizontal loops inside the ganglion are fiducial marks and are used for scaling and aligning. Afferent type #12 (also referred as X) is the only afferent that projects bilaterally. All other panels show the remaining 12 classes of afferent types shown from the same view asB. The afferent type numbers are shown in the top left corners. Scale bar (in A), 50 μm.
