Respuesta :
Answer: Jane surfers from retrograde amnesia,while Joan suffers anterograde amnesia.
Explanation: retrograde amnesia is were one can remember older memories but can not remember newer ones.while Anterograde is unable to form new memories,but can remember passed events.
Answer:
True.
Explanation: Amnesia is general loss of memories
When an individual (e.g Joan)failed to remember past events, pre-stored in the brain just before a particular period or date of an occurrence or incidents that lead to the amnesia;but with abilities to make new memories of recent events Retrograde amnesia sets in. Thus the individual's memory of the events that happened before the amnesia faded out and the subject failed to recollects.
Structurally; the hippocampus is for storage of short memories. Therefore retrograde amnesia should arise as a result of injuries (stroke, hypoxia, heavy s blow to the head, tumours) to the other regions of the brain connected with long term memories.E.g ( Broca's and Wernickle regions(language processing and speeach ) Damages to this region affect recollection of memories associated with language.
However when an individual( e,g Jane) fails to create new memories after the event that produce amnesia but with ability to recollect past events that occurred before amnesia; anterogade amnesia sets in. Thus such individuals failed to recollect most recent events, and therefore failed to make recent memories. It is due to disruptions in the cortical connections(formed by hypothalamus and thalamus) between the short-term memory storage hippo-campus and the long-term memory storage regions the cortex, so that short memory stored in the hippocampus are lost in transmission because they are not delivered for storage at the cortex.
it is caused by trauma to the hippocampus, cortical structures, or by effects of diseases and drugs to theses areas of the brain.
