这项研究的长期目标是有助于理解 视觉感知和视觉引导的生理机制 为便于治疗、改善和预防而采取的行为 由创伤、疾病和发育引起的视力障碍 异常现象。 除了纹状皮质外，还有一大片大脑皮质 灵长类动物参与视觉感知和视觉引导行为。 大脑皮质包括纹前皮质、下颞叶皮质(IT)和 颞上多感觉区(STP)。正在进行的关于 纹前皮质、IT皮质和STP皮质的功能将继续存在 使用生理学、解剖学和行为学方法。一个主要目标是 确定纹前区MT在知觉中的作用 运动和这一角色背后的神经回路。第二个主要目标 是分析颞叶上多感觉区在大脑中的作用 方位、定位和眼球运动，以确定来源 它的视觉输入，并确定它在视觉功能中所起的作用 在膝纹系统受损的情况下幸存下来，也就是在“失明”状态下。 第三个主要目的是进一步分析下位颞叶的作用。 大脑皮质中的形状和人脸识别以理解知觉 随着它的移除而产生的赤字。 这些目标与与健康相关的问题直接相关，例如 开发视觉假体，治疗术后知觉障碍 皮质损伤，以及术后感觉能力的最佳利用 导致视力受损或失明的脑损伤。

The long-term goal of this research is to contribute to the understanding of the physiological mechanisms of visual perception and visually guided behavior in order to facilitate the treatment, amelioration and prevention of disorders of vision caused by trauma, disease and developmental abnormalities. In addition to striate cortex, a vast expanse of the cerebral cortex of primates is involved in visual perception and visually guided behavior. This cortex includes prestriate cortex, inferior temporal cortex (IT) and the superior temporal polysensory area (STP). Ongoing research on the functions of prestriate cortex, IT cortex and STP cortex will be continued using physiological, anatomical and behavioral methods. One major aim is to determine the role of the prestriate area MT in the perception of movement and the neural circuitry underlying this role. A second major aim is to analyze the role of the superior temporal polysensory area in orientation, localization, and eye movements, to determine the source of its visual input and to ascertain the role it plays in the visual functions that survive damage to the geniculostriate system, i.e. in "blind sight". A third major aim is to analyze further the role of the inferior temporal cortex in shape and face recognition in order to understand the perceptual deficits that follow its removal. These aims are directly relevant to such health related problems as the development of visual protheses, the treatment of perceptual deficits after cortical damage, and the optimal utilization of sensory capacities after brain damage that results in impaired vision or blindness.
