总体目标1。检查认知功能的PET和FMR成像所涉及的基本技术和方法问题。2.应用多次注射[150]水PET和功能磁共振成像方案，以绘制涉及认知操作或功能的系统，例如定时、计划、排序、注意、语言、情感和记忆。3.将其应用于健康正常人的认知研究。4.应用它们来探索发生在被假设为神经发育起源的精神疾病(即精神分裂症和自闭症)中的认知功能障碍，以及由局灶性血管病变引起的认知功能障碍。5.利用它们来探索急性和长期使用尼古丁、大麻和酒精等令人上瘾的精神活性物质造成的认知功能障碍。

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.
