对猕猴中颞视觉区（MT）的单个神经元进行记录，并研究它们的方向和方向选择性。从单个纹状皮层 (V1) 神经元进行记录，以便与 MT 区域的观察结果进行直接比较。使用 3 种类型的移动刺激研究 110 个 MT 神经元的方向选择性：狭缝、单点和随机点场。所有 MT 神经元都使用一种或多种这些刺激进行定向选择性。 MT 神经元对所有刺激表现出广泛的方向调节带宽（最小值 = 32°，最大值 = 186°，平均值 = 95°）。所有 3 种刺激类型的反应都是强烈单向的且幅度相似。 MT 区域代表了 V1 区域的进一步专业化，用于刺激运动处理。猕猴和猫头鹰猴 MT 区域的方向和方位调节之间的显着相似性支持了这些区域是同源的建议。
Recordings were made from single neurons in the middle temporal visual area (MT) of the macaque monkey and their direction and orientation selectivity was studied. Recordings were made from single striate cortex (V1) neurons in order to make direct comparisons with the observations in area MT. Direction selectivity of 110 MT neurons was studied with 3 types of moving stimuli: slits, single spots, and random-dot fields. All of the MT neurons were directionally selective using one or more of these stimuli. MT neurons exhibited a broad range of direction-tuning bandwidths to all stimuli (minimum = 32.degree., maximum = 186.degree., mean = 95.degree.). Responses were strongly unidirectional and of similar magnitude for all 3 stimulus types. Area MT represents a further specialization over area V1 for stimulus motion processing. The marked similarities between direction and orientation tuning in area MT in macaque and owl monkey support the suggestion that these areas are homologues.
