Re: [agi] Neural representations of negation and time?
Hi Eugen, Here's some research to suggest that representations of space and time might not be so different. From the abstract: The present paper evaluates the claim that abstract conceptual domains are structured through metaphorical mappings from domains grounded directly in experience. In particular, the paper asks whether the abstract domain of time gets its relational structure from the more concrete domain of space. Relational similarities between space and time are outlined along with several explanations of how these similarities may have arisen... An interesting read. http://psychology.stanford.edu/~lera/papers/metaphors.pdf (By the way, I'm new here; looking forward to meeting you all.)

[agi] Neural representations of negation and time?
Various people have the notion that events, concepts, etc., are represented in the brain as a combination of various sensory percepts, contexts, subconcepts, etc. This leads to a representational scheme in which some associational cortex links together the sub-parts making up a concept or a remembered event or even a proposition. Antonia Damasio's convergence zones are an example. Does anyone have any ideas for neural representations of negation? How could such a system represent a negated proposition? I'm also interested in ideas about neural representations of time. How, when memories are stored, are they tagged with a time sequence, so that we remember when and/or in what order they happened, and how do we judge how far apart in time events occurred? Is there some brain code for time, with a 1D metric on it to judge distance? --- To unsubscribe, change your address, or temporarily deactivate your subscription, please go to http://v2.listbox.com/member/[EMAIL PROTECTED]
