PSY270H5 Lecture Notes - Temporal Lobe, Anterograde Amnesia, Retrograde Amnesia
Document Summary
Two different types of long term memory: declarative (explicit) and non-declarative (implicit - unconscious memories)! Retrograde amnesia: memory loss for events prior to trauma ! Due to some sort of injury, trauma ! Don"t remember what happened in the past ! The extent of the memory loss depends on the severity of the trauma! Amnesia is graded: loose the memory right before the injury ! Amnesia does tend to improve over time (comes back from oldest to newest memory; there there are some points that don"t come back all together)! Anterograde amnesia: memory loss for events after trauma ! This does not improve over time ! i. e. h. m: ! Seizures started at 10 years old ! By 27, they were so sever that he could no longer work - they became intractable ! Bilateral removal of medial temporal lobe in 1953 ! Don"t know what causes seizures what we do know that seizures start at one part brain !
