Beauty in Architecture: No, not a luxury; only a necessity
No full textCan beauty in architecture nourish the human emotional brain? Semir Zeki, Professor of Neuroaesthetics at University College London argues that it does. He goes further in suggesting it should be a quality in all buildings and that humanity has the ability to recognise this beauty across all cultural divides. The appreciation of beauty, no matter where found, is hardwired into our brains
Non-binding relationship between visual features
No full textThe answer as to how visual attributes processed in different brain loci at different speeds are bound together to give us our unitary experience of the visual world remains unknown. In this study we investigated whether bound representations arise, as commonly assumed, through physiological interactions between cells in the visual areas. In a focal attentional task in which correct responses from either bound or unbound representations were possible, participants discriminated the colour or orientation of briefly presented single bars. On the assumption that representations of the two attributes are bound, the accuracy of reporting the colour and orientation should co-vary. By contrast, if the attributes are not mandatorily bound, the accuracy of reporting the two attributes should be independent. The results of our psychophysical studies reported here supported the latter, non-binding, relationship between visual features, suggesting that binding does not necessarily occur even under focal attention. We propose a task-contingent binding mechanism, postulating that binding occurs at late, post-perceptual, stages through the intervention of memory
Non siamo liberi di non innamorarci. Conversazione con Semir Zeki
No full textThe interview is based on some thesis of Semir Zeki’s last book, Splendours and Miseries of the Brain. The founder of the International Institute of Neuroaesthetics (London 2001) wrote that a very different kind of knowledge can be acquired by the brain in the experience of art. It seems that he recognizes there can be a kind of “intelligence” in perception, while he writes about microcosciences of perception being located in the same areas where the information coming from the outside is elaborated and perceived. He explains the distinction between inherited “concepts” and acquired synthetic “concepts” of the visual brain. The theory of acquired concepts could also help in explaining the problem of taste: it seems that what we like in our lives is determined by the result (the synthesis) of those probabilities coming from our acquired synthetic brain concepts. Thus there wouldn’t be any free will in our aesthetical and love choices

The thinking eye: from Semir Zeki to John Onians
No full textIn 1994 Semir Zeki’s neuro-aesthetics formalizes the interdisciplinary approach to aesthetic facts, linking scientifically the brain to creativity. Consequently, the history of art becomes a neuroarthistory of the human mind, defined as such in 2005 by the historian John Onians. Finding a universal code, based on the nervous system and able to decipher each visual preference and every stylistic shift is the aim of this new analytic attitude. The identification of both the contextual element on which the gaze is intensively and frequently set, bringing to perceptual choices’ neural changes, and the particular mind plasticity modulation, as the genetic basis of any local forma mentis, clarifies how the brain conditions form the artistic manner. For this type of exam, the historian needs to observe in the creator’s and consumer’s brain the workings of the major cortical resources, such as neural plasticity, the rewarding system, the sectoring of the visual system, the intrinsic functional connectivity and mirror neurons. The discovery of this variability of “brain behavior” is the basis of the style shifts and the first step towards the neurohistory of art. Therefore, the named neuro-historical art analysis develops a narration of the somatosensory perceptions of the world, expressed through the language of forms. The latter infers, with the certainty of scientific data, the historical awareness and the aesthetic interpretation, opening up a new dimension of art criticism
Neuroarthistory : Discovering a Greater Appreciation of Art Through Science
No full textiv, 90 p.The author reviews several themes of neuroarthistory from theories of aesthetic interest, light perception and the eye, and the visual brain, considering the critical work of John Onians, Margaret Livingston, Semir Zeki, Tim Adams, Eric Fernie, Dominic Lopes, and V.
