Human Areas V3A and V6 Compensate for Self-Induced Planar Visual Motion
Fischer, E.,Bulthoff, Heinrich H.,Logothetis, Nikos K.,Bartels, A. Cell Press 2012 Neuron Vol.73 No.6
Little is known about mechanisms mediating a stable perception of the world during pursuit eye movements. Here, we used fMRI to determine to what extent human motion-responsive areas integrate planar retinal motion with nonretinal eye movement signals in order to discard self-induced planar retinal motion and to respond to objective (''real'') motion. In contrast to other areas, V3A lacked responses to self-induced planar retinal motion but responded strongly to head-centered motion, even when retinally canceled by pursuit. This indicates a near-complete multimodal integration of visual with nonvisual planar motion signals in V3A. V3A could be mapped selectively and robustly in every single subject on this basis. V6 also reported head-centered planar motion, even when 3D flow was added to it, but was suppressed by retinal planar motion. These findings suggest a dominant contribution of human areas V3A and V6 to head-centered motion perception and to perceptual stability during eye movements.

Head and neck cancers represent an aggressive form of neoplastic diseases thatwarrant surgical resection, in order to achieve optimal outcomes. Moreover, theinvolvement of the carotid artery is associated with a dismal prognosis and radicaltumor resection becomes challenging. The current case report presents a patientwith locally metastatic neck carcinoma attached to the right carotid bifurcation,involving both the external and internal carotid arteries up to the distal segmentof the internal carotid artery (ICA) at the level of the C1 vertebra. The patient underwenten bloc tumor and vessel resection. The carotid artery was reconstructedusing an interposition graft from the common carotid artery to the ICA by meansof an autologous saphenous vein graft. A vertical mandibular osteotomy wasperformed, in order to expose the distal ICA. The postoperative recovery was uneventful. The patient was under follow-up for six months, without any signs ofrecurrence.
