The brain does not always obey itself and can produce non-pathological excess.

Evidence

There is a cerebral con- flictuality, there is a tension between the neuronal and the mental, there is always the possibility that one or another trace will not convert into an image, that this or that opening will not be made, that this or that neuronal arrangement will not rise to the level of consciousness. The story is complex. We must consider that in a certain sense the brain does not obey itself, that it manufactures events, that there can be an excess in the system, an explosive part that, without being pathological, refuses to obey. — Catherine Malabou, What Should We Do with Our Brain?, 258

• DEFINE: This ‘explosive part that refuses to obey’ is plasticity’s explosive moment versus flexibility’s mere adaptation.
