Sensations and perceptions of the world are typically accurate, especially with focused attention. However, they are sometimes inaccurate, which can lead to damaging consequences. Understanding how the human brain processes sensory information to form coherent and representative perceptions of the world is therefore scientifically important and has broad implications for national health (e.g., radiologists detecting a tumor), security and defense (e.g., accurately responding to a perceived threat), and general safety and well-being (e.g., correctly perceiving the color of a traffic light). With funding from the National Science Foundation, this research assesses how attention and associated changes in brain activity facilitate the successful combination of different types of sensory information into accurate perceptions. By focusing on errors in perceptual binding, such as misperceiving the color of one object as being the color of another nearby object, these studies will provide insights into the brain states that allow perception to proceed with precision and those that cause perception to fail. In addition to advancing scientific knowledge about the brain, this research will provide training opportunities to many students, including high school and undergraduate students as well as underrepresented students in the STEM fields. The proposed experiments will examine the cognitive and neural mechanisms involved with visual feature binding and multisensory integration. The investigators will use converging methods to test whether modulations of attention and neural oscillations affect sensory integration. These methods include structural and functional magnetic resonance imaging (MRI) to measure neural activity during successful and unsuccessful visual feature binding and multisensory integration, electroencephalography (EEG) and fast signal optical imaging to measure changes in oscillatory neural activity prior to and after sensory integration, and rhythmic transcranial magnetic stimulation (TMS) to alter sensory integration by modulating and inducing phase-controlled neural oscillations. These studies will shed light on how sensory information that is processed in discrete regions of the human brain might be combined through neural oscillations to produce coherent representations of the external world. They will also provide a better understanding of failures in perception. By examining how different brain regions integrate information through synchronized neural activity, these studies may also provide important clues for generating strategies and rehabilitative tools for individuals with a variety of congenital, developmental, and acquired impairments that affect sensory processing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

对世界的感觉和感知通常是准确的，尤其是在注意力集中的情况下。然而，它们有时不准确，这可能会导致破坏性后果。因此，了解人脑如何处理感官信息以形成对世界的连贯且具有代表性的感知具有重要的科学意义，并且对国家健康（例如，放射科医生检测肿瘤）、安全和防御（例如，准确响应感知到的威胁）以及一般安全和福祉（例如，正确感知交通灯的颜色）具有广泛的影响。在美国国家科学基金会的资助下，这项研究评估了注意力和大脑活动的相关变化如何促进不同类型的感官信息成功组合成准确的感知。通过关注知觉结合中的错误，例如将一个物体的颜色误认为是附近另一个物体的颜色，这些研究将深入了解允许知觉精确进行和导致知觉失败的大脑状态。除了推进有关大脑的科学知识之外，这项研究还将为许多学生提供培训机会，包括高中生和本科生以及 STEM 领域代表性不足的学生。拟议的实验将检查与视觉特征结合和多感觉整合有关的认知和神经机制。研究人员将使用聚合方法来测试注意力和神经振荡的调节是否会影响感觉统合。这些方法包括结构和功能磁共振成像（MRI），用于测量成功和不成功的视觉特征结合和多感觉整合期间的神经活动，脑电图（EEG）和快速信号光学成像，用于测量感觉整合之前和之后振荡神经活动的变化，以及节律性经颅磁刺激（TMS），通过调制和诱导相控来改变感觉整合 神经振荡。这些研究将揭示人脑离散区域处理的感觉信息如何通过神经振荡组合起来，以产生外部世界的连贯表征。它们还将提供对感知失败的更好理解。通过检查不同的大脑区域如何通过同步神经活动整合信息，这些研究还可能为为患有影响感觉处理的各种先天性、发育性和后天性障碍的个人制定策略和康复工具提供重要线索。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
