概括

较高的信号,CUB,EGF类域含有1 (Scube1) 基因表达在老鼠背中条纹体 (DMS) 中与反向学习期间的坚持性错误增加相关,这表明它在认知不灵活性中发挥了作用.

科学领域:

神经科学是一个神经科学.
遗传学是一个遗传学.
行为科学行为科学

背景情况:

强迫症 (OCD) 与逆转学习缺陷和改变的皮质 - 状路径有关.
强迫症风险基因对条纹基因表达和体内认知不灵活性的影响尚未完全理解.
在行为灵活性中,Scube1的作用是未知的,Scube1是一种涉及血管/炎症信号的分泌糖蛋白.

研究的目的:

调查OCD候选基因,特别是Scube1的背中条体 (DMS) 表达与逆向学习期间在老鼠中的坚持性反应之间的相关性.

主要方法:

雄性李斯特帽鼠接受了空间区分任务,在会话内进行反转.
使用SYBR绿色实时聚合酶链反应 (RT-qPCR) 分析DMS组织以量化基因表达.
斯库贝1,Wdr7,Chd8和Sapap3的表达水平与坚持性错误相关.

主要成果:

在DMS中Scube1表达显示出与坚持性误差有显著的正相关性 (r(39) =0.35;p=0.027).
在Wdr7,Chd8或Sapap3表达和坚持性错误之间没有发现显著的关联.

结论:

在大鼠DMS中Scube1表达升高与增加的认知不灵活性有关,通过坚持性反应表明.
这表明Scube1在强迫症病理生理学中涉及血管/炎症通路的潜在作用.
研究结果支持使用动物模型和风险基因标来研究强迫症机制.

Purposive Learning

E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a bonus...
