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 are using a visual stimulus paradigm that produces well-characterized localized neural inhibition in primary visual cortex to test whether, on a fine spatial scale, the positive BOLD response is more closely related to the neural output or the local neural inhibition. In the past year we have published one paper demonstrating that the V1 BOLD response correlates better with the magnitude of the local neural inhibition than with the local neural output; a second manuscript is in preparation.

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。 我们正在使用的视觉刺激范例，产生良好的特征化的本地化的神经抑制在初级视觉皮层测试是否，在一个良好的空间尺度上，积极的BOLD响应更密切相关的神经输出或本地的神经抑制。在过去的一年中，我们已经发表了一篇论文，证明V1 BOLD反应与局部神经抑制的幅度比与局部神经输出的相关性更好;第二篇手稿正在准备中。
