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 study the neural basis of object recognition by recording neural responses from the inferotemporal cortex of macaque monkeys to understand how the neural responses can the amazing ability of primates, including humans, to remember and recognize complex visual images. In the projects published this year we have found that adaptation seems to affect only the early part of response in IT, leaving the "stored" representation to which the neural response converges unaltered (Liu et al, 2009). In addition, the quickness with which the cells' responses return to this stored location appears to depend on the likelihood that a particular visual stimulus will appear.

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。 我们通过记录猕猴颞下皮层的神经反应来研究物体识别的神经基础，以了解神经反应如何影响灵长类动物（包括人类）记忆和识别复杂视觉图像的惊人能力。 在今年发表的项目中，我们发现适应似乎只影响IT中反应的早期部分，留下神经反应收敛的“存储”表示不变（Liu et al，2009）。 此外，细胞的反应返回到这个存储位置的速度似乎取决于特定视觉刺激出现的可能性。
