觉醒的猕猴(猕猴和猕猴)月前回的背内侧部分，DP区的神经元对静止或移动的光刺激几乎没有反应。在大多数细胞中，不能确定循环的重构场。大约25%的单位在特定的注视位置上变得活跃，大部分在记录位置的同侧，并且在眼睛跳到这个位置后的潜伏期为70-150ms。当猴子专注地看着一个物体，如一张脸、一只手套、一只手或简单地拉着打开的门，并从视觉上探索它时，大约70%的神经元被强烈激活。这些刺激会引起注意，也会引起情绪反应。屏幕上闪现的拍摄对象或面孔只会产生很少的反应。因此，我们的观察表明，月前回的背内侧部分可能代表与视觉行为方面有关的活动，而不是与视觉图像本身的特征有关的活动。
Neurons in area DP, the dorsomedial portion of the prelunate gyrus of awake monkeys (Macaca mulattaandMacaca sylvana, responded only little if at all to stationary or moving light stimuli. Circcumscribed recceptive fields could not be determined in the majority of cells. About 25% of the units became active at a certain gaze position, mostly ipsilateral to the recording site, and with a latency of 70–150 ms after the eye had attained this position with a saccade. About 70% of neurons were activatd vigorously when the monkey looked attentively at an object, such as a face, a glove, a hand or simply towarsd the opening door, and explored it visually. These stimuli elicit attention as well as emotional responses. Photographed objects or faces flashed on a screen produced only little if any response. Our observations, therefore, suggest that the dorsomedial part of the prelunate gyrus may represent activities related to behavioral aspects of vision rather than to features of the visual image itself.
