Functional imaging research unit

总体目标1.研究认知功能PET和fMR成像中涉及的基本技术和方法问题。2.应用多次注射[150]水PET和fMRI协议，以映射涉及认知操作或功能的系统，如计时，计划，排序，注意力，语言，情感和记忆。3.应用于健康正常人认知功能的研究。4.应用它们来探索发生在被假设为具有神经发育起源的精神疾病中的认知功能障碍（即，精神分裂症和孤独症），以及由局灶性血管病变引起的认知功能障碍。5.使用它们来探索急性和慢性使用成瘾性精神活性物质（如尼古丁、大麻和酒精）导致的认知功能障碍。

Overall Aims 1. To examine basic technical and methodical issues involved in PET and fMR imaging of cognitive function. 2. To apply multiple injection [150]water PET and fMRI protocols in order to map systems involved in cognitive operations or functions such as timing, planning, sequencing, attention, language, emotion, and memory. 3. To apply them to the study of cognition in healthy normal individuals. 4. To apply them in order to explore disturbances in cognitive function that occur in mental illnesses that are hypothesized to have neurodevelopmental origins (i.e., schizophrenia and autism), as well as disturbances in cognitive function that result from focal vascular lesions. 5. To use them to explore disturbances in cognitive function resulting from acute and chronic use of addictive, psychoactive substances such as nicotine, marijuana and alcohol.
