Document Summary
Are very similar: semantic is tied to episodic - associates information about the fact. Inability to remember new information form that time (point of brain injury) forward: can last days, weeks, months, years, forever, can recover depends on extent on, thought to be psychogenic not biological trauma. Usually anterograde and retrograde amnesia occur together, some overlap. Inability to remember the past: ribbits law remote memories are more preserved, most likely to lose the memories closest to the time of the brain injury (ictus) He could still improve: hm improved over time took 3 dyas, hm did(cid:374)"t (cid:396)e(cid:373)e(cid:373)(cid:271)e(cid:396) had no explicit memory about doing the test before as he done it repeatedly. Memory consolidation: neuroactivity changes over time during recall, activity increases in pre-fronatal cortex over 90days, means that memory retrieval relocates to the cortex, semantic memory can be retrieved independently of the hippocampus and more dependent on prefrontal cortex. Whole life time of memories some are easily forgotten.
