@dagmaraka,
When I took physiological psych it was back in the dark ages, 1961. Much has been learned about the brain and its pathways since then, but I haven't read it all. Thus I still think of these things as nerve-net-reticuli (networks) that just keep being there and show up when the synapse/entry, or something, is breached.
Sometimes I like the old connections/rete, and so my memory burning voodoo will have to be very specific.
