Anterograde amnesia is associated with injury or damage to the hippocampus, specifically the CA1 region, which is responsible for the consolidation of new memories. The perirhinal and parahippocampal cortices are also involved in memory processes but are not as directly linked to anterograde amnesia as the CA1 region of the hippocampus. The amygdala is more associated with emotional memory and the central nucleus of the amygdala with fear conditioning, so damage to these regions would not necessarily result in anterograde amnesia.
