In our model, the unconscious domain contains (besides the processing domain and the unconscious control center UC)
a special collector for repressed ideas -- - 		 By Freud's it is also a part of Ego (but an unconscious part). After a few attempts to transform an idea-attractor belonging to the domain of doubtful ideas into some non-doubtful idea, SCC sends such a doubtful idea-attractor to the collector for repressed ideas.

What can one say about the further evolution of a doubtful idea in the collector for repressed ideas? It depends on a cognitive system (in particular, a human individual). In principle, this collector might play just the role of a churchyard for doubtful ideas. Such a collector would not have output connections and a doubtful idea (hidden forbidden desire, wish, impulse, experience) would disappear after some period of time.

However, Freud demonstrated that advanced cognitive systems (such as human individuals) could not isolate

In our model, this collector has an output connection with the unconscious control center UC. At this moment the existence of such a connection seems to be just a disadvantage in the mental architecture of a cognitive system. It seems that such a cognitive system was simply not able to develop a neuronal structure for 100\%-isolation of the collector for repressed ideas. However, later we shall see that the cyclic pathway: from SCC to the collector for doubtful ideas, then to UC, and, finally, again to SCC, has important cognitive functions. We might speculate that such a connection was specially created in the process of evolution. But we start with the discussion on negative consequences of existence of this cyclic pathway.
