The fact that hallucinatory form constants are perceived in rectified form suggests that some additional mappings are occurring beyond the initial stages of cortical representation. This however remains a grey area since we still don't really know how visual imagery becomes accessible to consciousness. I think this will become far clearer once we have good structural brain mapping tools, so that the exact transformations occurring between different brain regions can be better understood. ------------------------------------------- agi Archives: http://www.listbox.com/member/archive/303/=now RSS Feed: http://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: http://www.listbox.com/member/?member_id=8660244&id_secret=95818715-a78a9b Powered by Listbox: http://www.listbox.com
