Information processing theories of memory and skills can be reformulated in
terms of how categories are physically and temporally related, a process called
conceptual coordination. Dreaming can then...

要深入研究集体意向性，必须先回答四个问题：“意向性”为何物？意向性为什么可以是“集体”的？集体意向性有何种神经生理学基础？“集体意向性”为何重要？意向性是心灵借以指向、涉及或关于其自身以外的事物或事态的结构性特征；关于集体意向性的分析必须摆脱笛卡儿“我思”的幽灵，走出个体主义和还原性的分析，而坚持一种非还原性的整体主义；人脑“镜像神经元系统”的发现为集体意向性的存在提供了神经生理学的基础；自我、语...
对人的心理学研究结果显示，对比度检测学习可提高学习者对视觉刺激的对比敏感度，但其潜在的神经机制尚不清楚。该研究用二选一（two-alternative forced choice）方法训练3只猫（Felis catus）通过单眼进行对比度检测学习，发现每只猫对视觉刺激的对比敏感度随着训练而显著提高。该学习效果虽然对训练眼有明显的特异性，但部分学习效果可以传递给非训练眼，提示对比度检测学习可能会引起...
白介素1β对培养的大鼠皮层神经元钙通道电流的抑制作用
白介素1β 钙电流 膜片钳记录 皮层神经元
<
2010/4/20
白细胞介素1β（IL-1β）是重要的促炎细胞因子，在中枢神经系统（CNS）中发挥广泛的生物学功能。在病理条件下，细胞膜上电压门控钙通道的变化与疾病发展过程密切相关。虽然IL-1β和钙通道都在脑损伤和脑疾病过程中发挥重要作用，但目前还很少有两者之间相互关系的研究报道。该研究使用了培养的大鼠胎鼠皮层神经元和膜片钳记录技术，研究了长时间的IL-1β处理对电压门控钙通道电流的作用。结果表明，IL-1β在1...
