Tectospinal neurons (TSNs) in the caudal superior colliculus of the alert behaving cat have a sustained discharge that depends on the magnitude and direction of the vector between a food target and the visual axis. Each TSN has its 'optimal' vector for which it will be activated at a maximum discharge rate independent of whether the animal's head is free or fixed. The discharge is not due to prolonged stimulation of a TSN's receptive field since the discharge persists even when the target is not visible.
警觉行为猫的尾侧上丘中的顶盖脊髓神经元（TSNs）具有持续放电，该放电取决于食物目标与视轴之间矢量的大小和方向。每个TSN都有其“最佳”矢量，在该矢量下它将以最大放电率被激活，而与动物头部是自由的还是固定的无关。这种放电不是由于对TSN感受野的长时间刺激，因为即使目标不可见，放电仍会持续。
