讲座提要:
This talk traces the evolution of the visual receptive field (RF), the most profound concept in neuroscience, from the retina to the extrastriate cortex by summarizing the highlights of histological, neurophysiological, and neuroimaging studies. It starts with the early experiments by Hartline (1938) in the optic nerve of the frog, by Kuffler (1953) and Barlow (1957) in the retina of the cat, and continues with the recordings by Jung & Baumgartner (1952-1962) and Hubel & Wiesel (1959-1965) in the visual cortex of cat and monkey. An attempt is made to correlate neuronal findings to phenomenological and psychophysical observations.The study of population RFs, visual field maps, and inverse optics finally enables comparisons between microelectrode results in the monkey and fMRI findings in the human observer, thereby closing the circle to the beginning of psychophysics which started 150 years ago.
(讲座通过总结组织学,神经生理学和神经影像学研究的重点,追踪了在神经科学中视觉感受野(RF)从视网膜到外纹状皮层最深刻概念的演变。它始于Hartline(1938)在青蛙的视神经中的早期实验,由Kuffler(1953)和Barlow(1957)在猫的视网膜上进行,并由Jung&Baumgartner(1952-1962) 和Hubel&Wiesel(1959-1965)在猫和猴子的视觉皮层中继续记录。并试图将神经元发现与现象学和心理物理学观察联系起来。对人类RF视野图和反向光学的研究最终在猴子中的微电极结果与人类观察者的fMRI发现之间进行比较,从而追溯到150年前开始的心理物理学。)
