Fig. 11. Quasi-schematic representation of the electroresponsive structure of the DON. Schematic representation of the postulated neuronal circuitry superimposed on a cross-section of the DON. The molecular layer at the top of the cross section (green dots) is the location of all the apical dendrites of the principal neurons. The elongated cell bodies (in red) are located at the middle of the DON and the incoming afferent nerve innervates the basal dendrites in the deep layer (in yellow). The broken yellow line delineates a hypothetic path of the recording. AEN, ascending efferent neurons; D, dorsal; V, ventral; L, lateral; M, medial; R, rostral; C, caudal.
