there are m...Thanks for your interesting comments.<br /><br />there are many references to alternative routes to specialized visual areas that by-pass V1. Below, I give three from our own most recent work, but the anatomical pathways that by-pass V1 were charted as long ago as 1969 and 1980 by others. I must emphasize that the papers below are quite technical.<br /><br />1. https://www.ncbi.nlm.nih.gov/pubmed/25426050<br />2.https://www.ncbi.nlm.nih.gov/pubmed/24118503<br />3.https://www.ncbi.nlm.nih.gov/pubmed/25126064<br /><br />I find your other comments very interesting. I am of the view that there is no rigorous definition of form, either in art or in science; it falls into a category that everyone "knows" but no one has defined adequately, perhaps with the exception of the Gestalt psychologists. And your observation that lines may be associated with other perceptual dimensions has somewhat distracted from its "stand alone" status.<br /><br />Regards,<br /><br />Semir ZekiS.Z.https://www.blogger.com/profile/05135219380052959664noreply@blogger.comtag:blogger.com,1999:blog-2135284651117634504.post-32750710246656493692015-10-05T15:51:27.141-07:002015-10-05T15:51:27.141-07:00Hi, I was wondering if you could provide the refer...Hi, I was wondering if you could provide the references for the alternative routes you describe in the V1 and the responses to edge detection later in the visual system?<br /><br />I think the question of what constitutes form perception and the role of line is one of the most fascinating and subtle I've come across (I do alot of line drawings that involve shifts in form and was doing research involving contextual shape level effects on perceptual organisation and detection). <br /><br /><br />I was wondering if you might agree that in some sense the very importance and autonomy of the line - that it can simultaneously give rise to 'flow' and weight, of stimulating softness or roughness, gentleness or violence, all kinds of seemingly disparate effects both perceptual and emotional - may in some sense disguise its autonomy? <br /><br />So despite the fact that 'the line' cuts through and creates percepts associated with other perceptual dimensions those very things are treated as mere associations rather than evidence of the deeper and more complex neurophysiological connections that you have just described.<br /><br />I also wonder what your assessment of the present state of the field of 'form perception' and whether you feel Kusne's assessment with respect to the difficulty of getting everyone to agree to rigorous and well formulated definitions still holds true? And, more pertinently, how it is that artistic exemplars may provide a better lead in overcoming this obstacle? <br /><br />C<br /><br /><br /><br /><br /><br /><br /><br /><br />Christopher Gillespienoreply@blogger.com
