精神分裂症是一种复杂的发育障碍,在发现病因和帮助有效治疗受折磨的人类方面对现代神经科学提出了挑战。一种方法是将人类神经精神障碍的症状群划分为离散的单元进行研究。多种动物模型用于研究脑个体发育、对精神活性化合物的反应、定义行为的底物。在精神分裂症患者死后的大脑中,额叶皮质区被发现有异常的解剖结构和神经递质水平。小鼠模型具有相当简单的遗传操作的优势,并在同一物种中提供了许多遗传变异。然而,直到最近,在小鼠的行为分析落后于灵长类动物和大鼠,特别是在额叶皮层区域的测试。目前关于小鼠前额叶解剖和功能的研究表明,小鼠是研究前额叶皮质功能的一种可行的动物模型。这篇综述强调了最近的发展,从行为范式测试眼眶和内侧前额叶皮质功能的药理学和遗传模型的人类精神分裂症。
Schizophrenia is a complex developmental disorder that presents challenges to modern neuroscience in terms of discovering etiology and aiding in effective treatment of afflicted humans. One approach is to divide the constellation of symptoms of human neuropsychiatric disorders into discrete units for study. Multiple animal models are used to study brain ontogeny, response to psychoactive compounds, substrates of defined behaviors. Frontal cortical areas have been found to have abnormal anatomy and neurotransmitter levels in postmortem brains from schizophrenic patients. The mouse model has the advantage of rather straightforward genetic manipulation and offers numerous genetic variations within the same species. However, until recently, the behavioral analyses in the mice lagged behind the primate and rat, especially with respect to test of frontal cortical regions. Current reports of mouse prefrontal anatomy and function advocate the mouse as a feasible animal model to study prefrontal cortical function. This review highlights the most recent developments from behavioral paradigms for testing orbital and medial prefrontal cortical function in pharmacological and genetic models of human schizophrenia.
