从上级丘顺向激活的额叶眼区神经元。神经生理学杂志。80：3331-3333，1998.解剖学研究表明，猴的额眼区（FEF）和上级丘（SC）是紧密相连的，生理学研究描述了FEF向SC发送的信号，但SC向FEF发送的信号尚不清楚。我们生理上确定和特点的FEF神经元，可能会收到输入的SC。52 FEF神经元被发现，被顺向激活的SC的中间层或更深层的电刺激。所有的神经元，我们测试（n = 34）放电响应视觉刺激。一半也放电时，扫视眼球运动。这提供了第一个直接证据，从SC到FEF的上行通路可能携带视觉和扫视相关信号。我们的研究结果支持一个假设，即SC和FEF双向互动的事件导致扫视一代。
Frontal eye field neurons orthodromically activated from the superior colliculus. J. Neurophysiol. 80: 3331-3333, 1998. Anatomical studies have shown that the frontal eye field (FEF) and superior colliculus (SC) of monkeys are reciprocally connected, and a physiological study described the signals sent from the FEF to the SC. Nothing is known, however, about the signals sent from the SC to the FEF. We physiologically identified and characterized FEF neurons that are likely to receive input from the SC. Fifty-two FEF neurons were found that were orthodromically activated by electrical stimulation of the intermediate or deeper layers of the SC. All the neurons that we tested (n = 34) discharged in response to visual stimulation. One-half also discharged when saccadic eye movements were made. This provides the first direct evidence that the ascending pathway from SC to FEF might carry visual- and saccade-related signals. Our findings support a hypothesis that the SC and the FEF interact bidirectionally during the events leading up to saccade generation.
