A = (N-O)/(S-O). You let O nodes overlap with every assembly. Then you divide up the non-overlapping S-O nodes per assembly among the remaining N-O nodes. But that really isn't a useful answer. If a cell assembly is a group of neurons that tend to all fire at the same time, then a useful optimization is to model the whole assembly as a single neuron. -- Matt Mahoney, [EMAIL PROTECTED] ------------------------------------------- agi Archives: https://www.listbox.com/member/archive/303/=now RSS Feed: https://www.listbox.com/member/archive/rss/303/ Modify Your Subscription: https://www.listbox.com/member/?member_id=8660244&id_secret=117534816-b15a34 Powered by Listbox: http://www.listbox.com
