A pathological, highly
energized value system exercises powerful downward constraints upon
specific, favored, cell assemblies. These in turn dictate the organization
and reactivity of specific neuronal systems at the expense of a more
generalized pattern of response. The process eventuates in the appearance of
a specific set of “symptoms’, i.e. stereotyped and overriding neuronal
responses. The symptoms then feed recursively the value system in a complex
self-sustaining feedback loop.
