中文简介:
在许多(也许是大多数)脊椎动物物种中,视觉代表了一种主要的感官形态,对于与外界的定位和交流至关重要。动物感知外部世界的能力取决于其提取和编码视觉图像的特定特征的能力。因此,脊椎动物视网膜的输出不是由光感受器层中的光子吸收产生的2D视觉图的简单表示,而是作为强调物种特定行为需求的抽象表示传递。讲座将引导我们通过复杂的路径从简单的电磁信号到形成视觉表现的视觉刺激。最近发现的视网膜机械敏感离子通道将用作分子生理学可以统一希腊现象学,现代神经科学和医学的一个例子。
课程简介: In many, perhaps most, vertebrate species, vision represents a dominant sensory modality that is essential for orientation and communication with the outside world. An animal’s ability to perceive the external world is conditioned by its capacity to extract and encode specific features of the visual image. Thus, the output of the vertebrate retina is not a simple representation of the 2D visual map generated by photon absorptions in the photoreceptor layer but rather is transmitted as an abstract representation that emphasizes species-specific behavioral needs. The lecture will lead us through the complex path of the visual stimuli on its way from a simple electromagnetic signal to formation of a visual representation. The recently discovered retinal mechanosensitive ion channels will be used as an example through which molecular physiology could unify Greek phenomenology, modern neuroscience and medicine.
