Damage to specific areas can result in reduced or eliminated ability to encode new explicit memories, giving rise to anterograde amnesia.[5] Patients suffering from anterograde amnesia may have episodic, semantic, or both types of explicit memory impaired for events after the trauma that caused the amnesia. This suggests that memory consolidation for different types of memory takes place in different regions of the brain. Despite this, current knowledge on human memory is still insufficient to "map out" the wiring of a human brain to discover which parts of which lobe are responsible for the various episodic and semantic knowledge within a person's memory.
