Convergence of visual, haltere, and prosternai inputs at neck motor neurons of Calliphora erythrocephala

摘要: Neck muscles of Calliphora erythrocephala, situated in the anterior prothorax, are innervated on each side by 8 motor neurons arising brain (cervical nerve neurons, CN1–8) and at least 13 prothoracic ganglion (anterior dorsal frontal ADN1,2 FN1-11). Three prominent (CN6 FN1,2) described detail with special emphasis their relationships giant visual interneurons from lobula plate, haltere interneurons, primary afferents prosternal organs halteres. These sensory detect head movement body yaw, respectively. Neuronal indicate that is under multimodal control includes motion-sensitive previously supposed to mediate optomotor response flying flies. The pathways provide anatomical substrates for optokinetic yaw-incurred movements behavioural studies have shown must exist.
