Dear Khalaf,

Thank you very much for your beautiful paper

Khalafalla O. 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.

Nope. I'm afraid you got it all wrong.

Gladly.

I'm afraid it isn't,

The story goes back to November 1999,

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.
