My hypothesis is that when the nodes in a cluster are activated, this then leads to the recruitment of other associated nodes not in the cluster, into a contextually-appropriate transient assembly ... and that much of what's interesting in cognitive neurodynamics has to do with these transient assemblies and their interactions... which of course Granger does not touch on... Re consciousness, I tend to agree with Greenfield's hypothesis that wide-ranging transient neural assemblies are associated with conscious awareness. This harmonizes well with the hypothesis I make in the Hidden Pattern, that the more information-theoretically "intense" patterns in the brain will tend to correspond to the more subjectively intense consciousness experiences... -- Ben ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=8660244&id_secret=56358149-2d450f
