  BrainMind.com - Confabulation & Delusional Denial
In that all other attempts to elicit confabulation from this patient was unsuccessfully, it appears that in the single instance of confabulatory responding, once"consciousness"returned and events again began to e recorded in memory, the patient was faced with the remnants of behavior (i.e., the hat in his hands), which he then attempted to explain.
Confabulation is not a unitary syndrome and does not appear to result from a specific type of lesion or in conjunction with a particular constellation of disorders.
Confabulation also often results from a tendency to engage in gap filling, which, in turn, may be secondary to memory loss or intra/inter-cerebral disconnection.

 Memory Loss & the Brain
Confabulation is a memory disorder that may occur in patients who have sustained damage to both the basal forebrain and the frontal lobes, as after an aneurysm of the anterior communicating artery.
Confabulation is defined as the spontaneous production of false memories: either memories for events which never occurred, or memories of actual events which are displaced in space or time.
Neither should confabulation be confused with false memory syndrome, the phenomenon whereby otherwise normal individuals suddenly "remember" supposedly-repressed incidents of childhood abuse or other trauma.

 Mind Hacks: Confabulation
It is thought that confabulation occurs because the areas of the brain involved in controlling recollection and evaluating the resulting memories (particularly the the frontal lobes) are damaged.
Confabulations are thought to be different from delusions, as they are usually not fixed, with some patients reporting different things when asked the same question again.
The study of confabulation is also interesting because it inspired one of the only neuropsychological studies to use a qualitative approach (i.e.

A confabulation is a fantasy that has unconsciously replaced fact in memory.
A confabulation may be based partly on fact or be a complete construction of the imagination.
The term is often used to describe the "memories" of people claiming to have been abducted by aliens, as well as "false memories" induced by therapists or interviewers, memories that often involve bizarre notions of satanic ritualistic sexual abuse of children.

 Encephalitis – Possible Outcomes – Confabulation
Confabulation is the phenomenon whereby patients with memory disorders may produce false memories.
Spontaneous confabulation, which may rove over a number of themes, sometimes is bizarre, and the content of which is often very preoccupying for the patient, seems to be the result of damage to the frontal lobes, particularly in the bottom part (ventro-medial) of the frontal lobes of the brain.
Where a person is experiencing confabulation, they should be referred back to the consultant in charge of their case with a view to discussing and managing the confabulation.

Confabulators may not show the autonomic signs of fear, but they may still experience fear of paralysis at a more intellectual or cognitive level and this itself may generate the thought that they are fine.
Confabulators often seem to go through a phase before they fully recover where they form a belief, then remember that it is ill-grounded.
Another related difference between confabulators and people with OCD or hypochondria is that in the confabulators there is a blunting or total lack of emotional (or at least autonomic) response, while OCD and hypochondria are accompanied by aversive, negative emotions.

Clinically, 'confabulation' is normally used to describe the manufacture of sometimes plausible, sometimes wildly implausible, fictions, especially by sufferers of Korsakoff's syndrome.
Some confabulations are, as he notes, quite plausible: if you did not know that the confabulator had been hospitalized for the past six months, you would have no difficulty accepting their stories.
Confabulations might be verbal analogues of utilization behavior: we may regularly produce such hypotheses, and would accept them but for the winnowing effects of our checking mechanisms.

Confabulation is a common expression of a variety of brain injuries, but of course not all lead to this symptom.
Although Hirstein strives to account for confabulation with a single mechanism, the maze of clinical and anatomical data he reviews strongly suggests that at the neural level there are different derailments, depending on the type of brain injury.
Confabulators, after all, remain rational in domains outside of the foci of their various syndromes, in contrast with more global breakdowns found in schizophrenia or dementia.

 Title: "Functional properties of neural circuits for vision"
Abbreviated confabulation maps a set of individual symbols, called assumed facts (each belonging to a different lexicon of symbols) to a set of symbols (called an expectation) belonging to yet another lexicon.
Confabulation is akin to pattern classification, with the differences being that the input is a set of symbols from disjoint lexicons (not a point in Euclidean space) and the output is not a single ‘class symbol,’ but a set of such symbols.
Confabulation is based upon a very limited type of knowledge (a collection of pairwise symbol conditional probabilities, which is assumed to be exhaustive).

 All in the Mind: 15 October  2005  - Confabulation - Unscrambling an enigma
If we look at what is confabulation, what is the experience of confabulation, one of its characteristics as it lately emerges, although the data is still very new, is that they really experienced it.
So in terms of the mundane confabulations maybe what’s going on here is that the patient has lost the normal tags or links that we have in our memories to link memories to a particular time or a particular place.
And there is some evidence now that confabulating patients are unable to do this, so they have a tendency to think that every thought that comes into their mind is real and report it as such.

It has been argued (Joseph, 1982) that confabulation may occur when the language centers of the left hemisphere are isolated from sources of information about which the patient is questioned, such that complete and accurate information is not fully available.
In these instances confabulation may occur as a result of attempts to fill the gaps in the information received with associations which are in some manner related to the fragments available (Joseph, 1982; Talland, 1961).
However, confabulation may also result due to other factors such as frontal lobe dysfunction such that (in these instances) an uninhibited flow of irrelevant information is transmitted to and organized by the language regions.

 Truth about Confabulation   (Site not responding. Last check: 2007-10-28)
The patients that DeLuca works with confabulate because of a rupture in a tiny blood vessel in the brain called the anterior communicating artery (ACoA).
The rupture of this tiny artery temporarily cuts off the normal flow of oxygenated blood to areas of the brain that are essential to the proper recall of memories.
At the Kessler Medical Rehabilitation Research and Education Corporation, where DeLuca and his colleagues conduct their research, neuropsychologists, physicians, and therapists help people with confabulation to become aware that some of the memories they recall, believe, and even passionately defend are inaccurate.

 MedFriendly.com: Confabulation
Confabulation is when someone unintentionally tries to cover up gaps in memories by fabricating experiences or situations through making up incorrect and bizarre responses to questions.
Since confabulation is unintentional, it is not the same as lying.
Confabulation is used as a defense mechanism and is seen in people with alcoholism, amnesia (memory loss), dementia, lead poisoning, head injury, post-traumatic states, Wernicke's syndrome, (a type of brain damage due to a vitamin deficiency) and Korsakoff's syndrome (another type of brain damage due to a vitamin deficiency).

 Zargoza, et al. (2001). Interviewing witnesses: Forced confabulation and confirmatory feedback increases false memories.
The forced confabulation effect occurs when subjects are pressed to confabulate information about a witnessed event and then later falsely recall memories for those events.
This experiment was identical to experiment 1 with the exception that delayed free recall was not tested, and the memory for the interview was tested immediately after administering the recognition test.
Participants remembered providing the confabulated items as responses, without remembering they had fabricated them; otherwise they would not have claimed they also remembered seeing the events.

Younger participants were more likely to claim confabulated items were in the tape than were older participants (but they were also more likely to say control items were in the tape).
In the forced confabulation case they might be expected to remember their initial response of denying that the item existed.
However, subjects may be especially convinced by confabulated events because they have integrated it into their own systems of knowledge and beliefs (Jim's note: Some have made similar arguments for how belief perseverance occurs).

To validate his hypothesis, Hecht-Nielsen and his colleagues demonstrated the use of confabulation for language generation.
Some 8,000 books worth of English-language text were streamed through a computer-based architecture, and when two consecutive sentences within a paragraph seemed topically coherent using a simple thought process, they were marked with symbols and linked.
“These items of knowledge along with confabulation were then used to carry out the continuation of a sentence based on the first three words alone, or the first three words and knowledge of the previous sentence.”
