Perceptual phenomena such as spatio-temporal illusions and masking are typically explained by psychological (cognitive) processing theories or large-scale neural theories involving inter-areal connectivity and neural circuits comprising of hundreds or more interconnected single cells. Subcellular mechanisms are hardly used for such purpose. Here, a mechanistic theoretical view is presented on how a subcellular brain mechanism of integration of presynaptic signals that arrive at different compartments of layer-5 pyramidal neurons could explain a couple of spatiotemporal visual-phenomenal effects unfolding along very brief time intervals within the range of the sub-second temporal scale.
诸如时空错觉和掩蔽等感知现象通常由心理(认知)加工理论或涉及区域间连接性以及由数百个或更多相互连接的单个细胞组成的神经回路的大规模神经理论来解释。亚细胞机制很少用于此目的。在此,我们提出一种机械理论观点,即到达第5层锥体神经元不同区室的突触前信号整合的亚细胞脑机制如何能够解释在亚秒时间尺度范围内沿着非常短的时间间隔展开的一些时空视觉现象效应。
