下颞叶皮层是正常视觉所必需的 以及成年人和猴子的视觉学习。 若干行 行为学、解剖学和生理学证据表明， 下颞叶皮层在第一年继续发育， 产后生活 将通过研究 正常饲养大鼠颞叶下神经元的特性 猕猴在生命的第一年的不同时间， 它们与成年人颞下神经元的特性有关 猴子 研究的单个神经元特性包括 反应性、模态特异性、感受野大小和 位置和刺激选择性。 特定视觉体验在儿童认知发展中的作用 还将研究下颞神经元的特性。 在成年猕猴中， 选择性地面对。 在从出生起饲养一年的动物中 在没有接触面孔的情况下， 将与正常饲养的动物进行比较。 一些 动物也将被饲养， 刺激和下颞叶细胞对此的选择性 随后将对刺激措施进行测试。 拟议的研究应加强对 人类视觉学习和感知的发展及其 疾病、创伤和发育障碍的干扰。

Inferior temporal cortex is necessary for normal visual perception and visual learning in adult humans and monkeys. Several line of behavioral, anatomical and physiological evidence suggest that inferior temporal cortex continues to develop in the first year of post-natal life. This possibility will be examined by studying the properties of inferior temporal neurons in normally reared macaques at various times in the first year of life and comparing them to the properties of inferior temporal neurons in adult monkeys. The single neuron properties studied will include responsiveness, modality specificity, receptive field size and location, and stimulus selectively. The role of specific visual experience in the development of the properties of inferior temporal neurons will also be investigated. In adult macaques some inferior temporal neurons respond selectively to faces. In animals raised from birth for one year without exposure to faces the incidence of face-selective neurons will be compared to that in normally reared animals. Some animals will also be raised with extensive exposure to an artifical stimulus and the selectivity of inferior temporal cells for this stimulus will be subsequently tested. The proposed research should enhance understanding of the development of human visual learning and perception and its interference by disease, trauma and developmental disorders.
