POPULATION RECEPTIVE FIELD ESTIMATES IN HUMAN VISUAL CORTEX

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 我们介绍了功能磁共振成像方法估计神经元群体感受野（pRF）。这些方法建立在测量对环和楔的反应的传统视野映射的基础上 模式显示在一系列的视野位置，并估计在视野中产生最大的反应的单一位置。新方法计算出一个群体感受野模型 从对各种刺激的反应中获得，并估计视野图以及其他神经元群体特性，如感受野大小和偏侧性。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. We introduce functional MRI methods for estimating the neuronal population receptive field (pRF). These methods build on conventional visual field mapping that measures responses to ring and wedge patterns shown at a series of visual field locations and estimates the single position in the visual field that produces the largest response. The new method computes a model of the population receptive field from responses to a wide range of stimuli and estimates the visual field map as well as other neuronal population properties, such as receptive field size and laterality.
