Pierre Jean Georges Cabanis (1757-1808): an early nineteenth century source for the concept of nervous energy in European behavioral neurosciences

The nineteenth century witnessed many advances in neuroscientific concepts. Among the notable are Charles Bell's (1774-1842) and Fran?ois Magendie's (1783-1855) identification of sensory and motor pathways, Thomas Henry Huxley's (1825-1895) elaboration of evolutionary theory in the context of comparative neuroanatomy, and Emile Du Bois-Reymond's (1818-1896) and Hermann von Helmholtz's (1821-1894) work in experimental neurophysiology and on the concept of nervous energy. In Germany, the idea that the nervous system consisted of two elements, one that generated nervous energy and another that conducted it throughout the body, had wide currency in mid-nineteenth century. In France, Pierre Jean Georges Cabanis (1757-1808), physician, philosopher, and one of the founders of modern psychophysiology, argued that the brain is the part of the body in which electricity is stored. In his Rapports du Physique et du Moral de l'Homme, published between 1796 and 1802 (translated into German under the title Verh?ltnis der Seele zum K?rper (1808)), Cabanis proposed new ideas on brain function, on the brain's own sensibility, on the concept of will, and on the chemical basis of nervous activity. In the Rapports Cabanis proposed a theory of how brain and nerves relate to thought and behavior. Foreshadowing later developments in neuropsychology, he suggested that different parts of the nervous system have separate functions. Despite the fact that Cabanis had many interesting ideas about brain function, he has been largely ignored by historians of neuroscience; e. g., he is mentioned briefly in Clark and Jacyna (1989), in only two footnotes in Neuburger (1897/1981), and not at all in Finger (1994). Cabanis's far-reaching theory of how the brain works helped shape understanding of the general notion of nervous energy in nineteenth-century European neuroscience.     

大卫·施特劳斯《耶稣传》(一)——经典选读之十三

大卫·施特劳斯(D.F.Strauss,1808-1874年)青年黑格尔派主要成员,杜宾根学派的主要代表。本期选读的是他的名著《耶稣传》。该选读内容分为两个部分,本文是第一部分。文章首先介绍了施特劳斯生平、著作及其影响;接着是他圣经新约进行历史考察所得出的结论,特别是我们从他书的目录可以看出他认为几乎整个新约都不过是神话。     

Lessons from beyond vision (sounds and audition)

Recent work on non-visual modalities aims to translate, extend, revise, or unify claims about perception beyond vision. This paper presents central lessons drawn from attention to hearing, sounds, and multimodality. It focuses on auditory awareness and its objects, and it advances more general lessons for perceptual theorizing that emerge from thinking about sounds and audition. The paper argues that sounds and audition no better support the privacy of perception’s objects than does vision; that perceptual objects are more diverse than an exclusively visual perspective suggests; and that multimodality is rampant. In doing so, it presents an account according to which audition affords awareness as of not just sounds, but also environmental happenings beyond sounds.     

"A moment's monument": the central vision of Italian sculptor Medardo Rosso (1858-1928)

One of the basic limitations on visual perception is that it is impossible, in any given moment, to see the world sharply and full of colors beyond the central area of the visual field. This fact was popularized and brought to the attention of artists in the nineteenth century. To accurately represent the 'impression', or vision of a single glance, an artistic work should contain only a central area in focus surrounded by a progressively greater blur. The work of the Italian sculptor Medardo Rosso (1858-1928) may be the first artistic representation of differences in central and peripheral acuity. Despite using the medium of sculpture, typically three-dimensional, Rosso conceived of his art as two-dimensional because in a given moment it is possible to view a scene from only one viewpoint. The analysis of Rosso's photographs of his own sculptures emphasizes the areas of detail and relative blur, allowing a reconstruction of his point de vue unique--where the observer should stand when viewing that specific sculpture. We argue that the role of central and peripheral vision in subjective perception is critical to understanding the work of Rosso, aptly defined by critics as monument d'un instant.     

The multi-item localization (MILO) task: measuring the spatiotemporal context of vision for action

We describe a new multi-item localization task that can be used to probe the temporal and spatial contexts of search-like behaviors. A sequence of four target letters (e.g., E, F, G, and H) was presented among four distractor letters. Observers located the targets in order. Both retrospective and prospective components of performance were examined. The retrospective component was assessed by having target items either vanish or remain once they had been located. This manipulation had little effect on search performance, suggesting that old target items can be efficiently ignored. The prospective component was assessed by shuffling future target and distractor locations after each response. This manipulation revealed that observers typically plan ahead at least one target into the future. However, even when observers cannot plan ahead, they are still able to ignore old targets. These findings suggest that both "what you did" and "what you intend to do" can influence the localization and selection of targets.     

The role of transcranial magnetic stimulation (TMS) in studies of vision, attention and cognition

Transcranial magnetic stimulation (TMS) can be conceptualized as a virtual lesion technique, capable of disrupting organized cortical activity, transiently and reversibly. The technique combines good spatial and temporal resolution and, moreover, because it represents an interference technique, can be said to have excellent functional resolution. The following is a review and discussion of the contribution which TMS has made to the study of vision, attention, development and plasticity and speech and language.

颜钧的平实之学

颜钧哲学思想的基调是儒家的。但颜钧在儒家思想的宣传、儒家理念的实践和儒家经典的解读等方面,都与儒家的传统方式有异,由此使颜钧学行思想表现为“率性而行”、“儒禅兼济”、“放心体仁”、“自立无私”四大特征。具此四大特征的颜钧学行思想,是对儒家思想的丰富和发展。     

The wonder of their voices: The 1946 Holocaust interviews of David Boder (New York: Oxford, 2010)

Writing a study of psychologist David Boder's 1946 displaced persons (DP) interview project gave me a chance to further document the substantial early response to the Holocaust. This was clearly one important piece of my study, and one that was eminently straightforward. Yet much of the research on Boder's project at the point in time that I carried it out was elliptical, partly because the primary interview materials were coming to light at an astonishing pace, partly because the archive collections were virtually untapped, and partly because of the misconception of Boder and his interview project itself.     

The indeterminacy of color vision

A critical survey of recent work on the ontological status of colors supports the conclusion that, while some accounts of color can plausibly be dismissed, no single account can yet be endorsed. Among the remaining options are certain forms of color realism according which familiar colors are instantiated by objects in our extra-cranial visual environment. Also still an option is color anti-realism, the view that familiar colors are, at best, biologically adaptive fictions, instantiated nowhere.I argue that there is simply no fact of the matter as to which of these remaining options is correct. I blame this indeterminacy on the fact that color vision exhibits several of the hallmarks of a modular input system, as described by Jerry Fodor in The Modularity of Mind.Finally, I speculate that the range of live options falling within the scope of the indeterminacy may be even broader than initially indicated.
