For patients with hippocampal pathology, disagreement exists in the literature over whether retrograde amnesia is temporally limited or very extensive depending on whether the anatomical damage is restricted to this structure or also involves additional temporal cortex. We report a comprehensive assessment of retrograde and anterograde memory functions of a severely global amnesic patient (VC)....

The present study aims to compare quality of life of victims with long and short term post-traumatic amnesia and to analyze the relation between quality of life and length of amnesia, including or not the comatose period. This prospective cohort study, gathered data during the hospital stay and 3 and 6 months post- trauma. Blunt traumatic brain injury patients, over 14 years old, with no prior ...

To this day, it remains unresolved whether experimental amnesia reflects failed memory storage or the inability to retrieve otherwise intact memory. Methodological as well as conceptual reasons prevented deciding between these two alternatives: The absence of recovery from amnesia is typically taken as supporting storage impairment interpretations; however, this absence of recovery does not pos...

Studies have shown lower false recognition of semantically related lure words in patients with global amnesia than in matched controls. This pattern has been interpreted as suggesting that medial temporal and diencephalic structures that are damaged in amnesia and that contribute to veridical memory also contribute to false recognition. It has been argued that whereas controls form and retain a...

Suggestions of amnesia were given to 144 Ss in a 2 X 2 X 4 factorial experiment. The independent variables were: (1) spoken versus recorded presentation of suggestions; (2) presence versus absence of hypnotic induction; and (3) 4 types of suggestions for amnesia—authoritative ("You will not remember I"), permissive ("Try to forget"), suggestions to simulate, and no suggestions. Variable 1 did n...

'1'he process of remembering during post-hypnotic amnesia was investigated by exploring the organization of recalled material in subjects displaying only partial amnesia. During three standardized hypnosis scales, suggestions of posthypnotic amnesia were administered to 112 subjects. Hypnolizahle subjects tended to recall the scale items in random chronological order, compared to the relatively...

A connectionist model is presented, the TraceLink model, that implements an autonomous "off-line" consolidation process. The model consists of three subsystems: (1) a trace system (neocortex), (2) a link system (hippocampus and adjacent regions), and (3) a modulatory system (basal forebrain and other areas). The model is able to account for many of the characteristics of anterograde and retrogr...
