Vertebrates use the vestibulo-ocular reflex to maintain clear vision during head movements. This reflex requires eye-velocity commands from the semicircular canals to be integrated (mathematically) to produce eye-position commands for the extraocular muscles. This is accomplished by a neural network in the caudal pons. A model of this network is proposed using positive feedback via lateral inhibition. The model has been adapted to a learning network. We have developed a synaptic learning rule using only local information to make the model more physiological.
脊椎动物利用前庭眼反射在头部运动时保持清晰的视觉。这种反射需要将来自半规管的眼速度指令进行(数学上的)整合,以产生针对眼外肌的眼位置指令。这是由脑桥尾部的神经网络完成的。通过侧向抑制的正反馈提出了该网络的一个模型。该模型已被改编为一个学习网络。我们仅利用局部信息开发了一种突触学习规则,以使模型更具生理学特性。
