چکیده
episodic memory store of personally experienced events from the past, including details not only of the content of the episode but also of its context — when and where it occurred. semantic memory our general knowledge about the world, such as information about words and their meanings, facts, concepts, objects and people; typically retrieved without recollection of where and when the information was initially acquired. hippocampal complex structures located in the medial temporal lobe of the human brain (e.g., the hippocampus, subiculum, parahippocampal gyrus, and entorhinal cortex); implicated in the learning and temporary storage of recent memories. temporal lobe/neocortex the area of the brain considered the permanent store of our episodic and semantic memories.

Imagining fictitious and future experiences: Evidence from developmental amnesia
Patients with bilateral hippocampal damage acquired in adulthood who are amnesic for past events have also been reported to be impaired at imagining fictitious and future experiences. One such patient, P01, however, was found to be unimpaired on these tasks despite dense amnesia and 50% volume loss in both hippocampi. P01 might be an atypical case, and in order to investigate this we identified...
متن کاملScene construction in developmental amnesia: An fMRI study☆
Amnesic patients with bilateral hippocampal damage sustained in adulthood are generally unable to construct scenes in their imagination. By contrast, patients with developmental amnesia (DA), where hippocampal damage was acquired early in life, have preserved performance on this task, although the reason for this sparing is unclear. One possibility is that residual function in remnant hippocamp...
متن کاملPreserved recognition in a case of developmental amnesia: implications for the acquisition of semantic memory?
We report the performance on recognition memory tests of Jon, who, despite amnesia from early childhood, has developed normal levels of performance on tests of intelligence, language, and general knowledge. Despite impaired recall, he performed within the normal range on each of six recognition tests, but he appears to lack the recollective phenomenological experience normally associated with e...
متن کاملNeuropsychological Generation of Source Amnesia: An Episodic Memory Disorder of the Frontal Brain
Source amnesia is an explicit memory (declarative) disorder, particularly episodic, where source or contextual information concerning facts is severely distorted and/or unable to be recalled. This paper reviews the literature on source amnesia, including memory distrust syndrome, and its accepted correlation with the medial diencephalic system and the temporal lobes, and the suggested linkage b...
متن کاملImpaired recognition memory on the Doors and People Test after damage limited to the hippocampal region.
There have been conflicting reports about the importance of the hippocampal region for recognition memory. Vargha-Khadem et al. (1997) described three patients who became amnesic early in life as a result of damage apparently limited to the hippocampal region. One of these patients (Jon) performed normally on the recognition portion of the Doors and People Test but was severely impaired in reca...
