Bushara, Takashi Hanakawa, Ilka Immisch, Keiichiro Toma, Kenji Kansaku & Mark Hallett. Neural correlates of cross-modal binding. Nature Neuroscience, 6(2) 190-195 (February 2003). I'm wondering what could be the neural "code" for cross-modal binding and cross-modal transfer in multimodal networks. We call it in psychology 'context', http://members.aon.at/chakalov/Penrose.html#NB http://members.aon.at/chakalov/faq.html but what could be its neural presentation? See also the process of 'filling-in' in the case of incomplete information, p. 120 and [Ref. 56] in Francis Crick & Christof Koch. A framework for consciousness. Nature Neuroscience, 6(2) 119-126 (February 2003). I will appreciate the opinion of your colleagues as well. Best regards, Dimi

P.S. Regarding the story at http://members.aon.at/chakalov/Penrose.html#NB , I'm wondering if you can understand the following string: Lapsus salami. Isn't it sort of self-referential? I'm curious to read more on the binding problem in Jacques Sougné (in press). Binding Problem. Encyclopedia of Cognitive Science. London: MacMillan. As to your very interesting fMRI study, http://members.aon.at/chakalov/Bushara.html do you know fMRI studies of mental rotation a la Alan Paivio? "The thing that you counted the corners of, that's what I mean by a mental image," http://www.unbf.ca/psychology/likely/demos/images1.htm See the dual coding theory at http://tip.psychology.org/paivio.html and recall the well-known example of mental rotation: Imagine a cube made of white plastic material with a 3 cm rib, painted blue, which is cut into 27 little cubes with a 1 cm rib. How many little cubes will have three blue sides, how many will have two, one or none? We have two things to consider: the rotating cube, and the rotator. The latter has the peculiar faculty of 'self-acting', but can you locate the 'rotator' in the human brain with fMRI? Perhaps only the neural correlates of the cube. Just guessing. I will appreciate your comments and those by your colleagues. Will keep them private and confidential. Best - Dimi

Dear Mark, Please reply to me only; I'm afraid your colleagues are deeply bored. On Tue, 08 Jul 2003 14:26:40 -0700, you wrote: [snip] > Following the links through Chakalov's e-references,

I'm afraid it isn't, http://members.aon.at/chakalov/Vecchi.html The story goes back to November 1999, http://members.aon.at/chakalov/Penrose.html#Hameroff > >and actualizes a single brain state from among a myriad
of Sounds intriguing, but you have to solve the binding problem, http://members.aon.at/chakalov/Bushara.html#PS I believe you'll be nominated for two Nobel prizes, for physics and physiology. Good luck. Dimi
