The somatosensory system involves the sense of touch, and the term haptic perception includes how objects are recognized by touch, as well as their spatial relations. In an interesting parallel with visual processing, there is evidence that the brain contains two pathways for information about touch, one for perceiving 'what' an object is, and the other for 'where' it is. This project will utilize current imaging technology (brain scanning by fMRI and MEG techniques) with human subjects to identify and localize the neural activity in tasks designed to utilize primarily one or the other pathway in response to tactile stimuli. Differences in the two types of tactile processing will reflect functional specialization in the somatosensory system. This award is in the Professional Opportunities for Women in Research & Education (POWRE) activity of NSF. It will provide a young woman a unique opportunity a a different campus to broaden her technical expertise in the field of cognitive neuroscience by getting training in neuroimaging, and bring that expertise back to enhance her teaching and research at her home institution, and so will have a significant impact on her career and on the home institution. The scientific results also will have an impact because a better understanding of haptic perception is important to sensory neuroscience in general, and could lead to substantial advances in artificial or assistive technologies, such as aids for the blind and for robotics.

躯体感觉系统涉及触觉，触觉感知一词包括如何通过触摸识别物体，以及它们的空间关系。 有证据表明，大脑包含两条关于触摸的信息通路，一条用于感知物体是什么，另一条用于感知物体在哪里。 该项目将利用目前的成像技术（通过功能磁共振成像和脑磁图技术进行大脑扫描）与人类受试者识别和定位的神经活动的任务，旨在利用主要是一个或另一个路径响应触觉刺激。 这两种类型的触觉处理的差异反映了躯体感觉系统的功能特化。 该奖项是在NSF的研究教育（POWRE）活动中为妇女提供的专业机会。 它将提供一个年轻女子一个独特的机会，一个不同的校园，以扩大她的技术专长，在认知神经科学领域通过获得神经成像培训，并把这种专业知识带回，以加强她的教学和研究在她的家乡机构，所以将有一个显着的影响，她的职业生涯和家庭机构。 科学结果也将产生影响，因为更好地理解触觉感知对感觉神经科学很重要，并可能导致人工或辅助技术的重大进步，例如盲人和机器人辅助。
