这项研究的长期目标是有助于理解 感知、认知和视觉引导的神经机制 为了更好地预防，诊断和治疗这些疾病， 由创伤、发育异常和疾病引起的功能。 在灵长类动物中，大约一半的大脑皮层与视觉有关。 感知、视觉学习和视觉记忆。除了条纹或 初级视觉皮层该皮层包括前纹状体和下颞叶 (IT)皮层在建议的时间内，正在进行的研究prestriate和IT 皮质将继续使用神经生理学，神经解剖学和 行为方法。纹前皮质研究的一个目的是 确定几个新发现的前纹状的视觉地形 视觉区域。第二个目标是确定“盲视”（即 视功能在条纹损伤后仍然存在，但没有意识） 取决于纹前区MT。 颞叶下皮层的研究有五个具体目标。第一 是研究注意力对IT细胞活动的影响。的 第二是研究心理表征和记忆的神经相关性， IT细胞的活动。第三是要研究的想法， IT反应的时间调制可以代表刺激因素和 注意力和记忆力等视网膜外影响。第四个目标是 分析IT皮层的神经网络， 同时记录的IT神经元之间的相互作用。第五个目标是 进一步研究信息技术的区域专业化和功能架构 皮层 这些目标直接关系到治疗等健康问题 大脑皮层受损后的视觉和知觉障碍， 脑损伤后感官能力的最佳利用， 视觉假体的发展，以及发展性 儿童疾病。

The long-term goal of this research is to contribute to the understanding of the neural mechanisms of perception, cognition and visually guided behavior in order to better prevent, diagnose, and treat disorders of these functions caused by trauma, developmental abnormalities and disease. In primates about half of the entire cerebral cortex is involved in visual perception, visual learning and visual memory. In addition to striate or primary visual cortex this cortex includes prestriate and inferior temporal (IT) cortex. In the proposed period, ongoing research on prestriate and IT cortex will be continued using neurophysiological, neuroanatomical and behavioral methods. One aim of the research on prestriate cortex is to determine the visual topography of several newly discovered prestriate visual areas. A second aim is to determine whether "blindsight" (i.e. the visual functions that remain after striate lesions but are not conscious) is dependent on prestriate Area MT. The research on inferior temporal cortex has five specific aims. The first is to study the effects of attention on the activity of IT cells . The second is to study neural correlates of mental representation and memory in the activity of IT cells. The third is to investigate the idea that the temporal modulation of IT responses may represent both stimulus factors and extra - retinal influences such as attention and memory. The fourth aim is to analyze neural networks in IT cortex by studying the functional interactions among simultaneously recorded IT neurons. The fifth aim is to further study the regional specialization and functional architecture of IT cortex. These aims are directly relevant to such health problems as the treatment of visual and perceptual disorders after damage to the cerebral cortex, the optimal utilization of sensory capacities after brain-damage, the development of visual protheses, and the treatment of developmental disorders in children.
