1. 144持续和短暂的视网膜神经节细胞的感受野中心映射在猫轻戊巴比妥麻醉。2.持续的中心，持续的偏离中心，短暂的中心和短暂的偏离中心的细胞有不同的平均大小的感受野中心，它们的分布之间有一些重叠。3.对于每一类细胞，中心领域有最小的场中心，逐步较大的场中心遇到更多的外围。4.所有类别的神经节细胞往往有轻微椭圆形的感受野中心。超过一半的感受野的主轴方向在水平20°以内。这些趋势是独立的瞳孔尺寸，或感受野偏心率或在视野中的位置。结果几乎肯定反映了视网膜布线的不对称性。5.两个细胞的39个测试是敏感的运动轴，在这两种情况下，首选和主轴是水平的。另一个细胞是定向特异性的。
1. Receptive field centres of 144 sustained and transient retinal ganglion cells were mapped in cats under light pentobarbitone anaesthesia. 2. Sustained on-centre, sustained off-centre, transient on-centre and transient off-centre cells had different mean sizes of receptive field centre, with some overlap between their distributions. 3. For each class of cell, central fields had the smallest field-centres; progressively larger field-centres were encountered more peripherally. 4. All classes of ganglion cells tended to have slightly elliptical receptive field centres. Major axes of over half of all receptive fields were oriented within 20° of horizontal. These trends were independent of pupil dimensions, or of receptive field eccentricity or position in the visual field. The results almost certainly reflect asymmetry in retinal wiring. 5. Two cells of thirty-nine tested were sensitive to axis of motion; in both cases the preferred and major axis were horizontal. A further cell was orientation specific.
