Therefore, despite anterograde amnesia preventing Wearing from learning new bits of information that can be explained in words (declarative memory), and also preventing him from storing new memories of events or episodes (also part of declarative memory), he has little trouble in retaining his musical abilities (procedural memory), though he has no conscious memory of having learned music.Another case in the literature is Eugene Pauly, known as E.P., a severely amnesic patient (owing to viral encephalitis) who was able to learn three-word sentences. He performed better on consecutive tests over a 12-week period (24 study sessions). However, when asked how confident he was about the answers, his confidence did not appear to increase. Bayley and Squire proposed his learning was similar to the process required by procedural memory tasks; E.P. could not get the answers right when one word in the three-word sentence was changed or the order of words was changed, and his ability to answer correctly, thus, became more of a "habit". Bayley and Squire claim the learning may have happened in the neocortex, and it happened without the conscious knowledge of E.P. They hypothesized the information may be acquired directly by the neocortex (to which the hippocampus projects) when there is repetition. This case illustrates the difficulty in separating procedural from declarative tasks; this adds another dimension to the complexity of anterograde amnesia.
In the 2011 light novel Danganronpa Zero, the protagonist and "Ultimate Analyst" Ryoko Otonashi has anterograde amnesia as a result of "The Tragedy", keeping note of her memories by writing into a journal at all times and using her speedreading to keep herself up to date. Seen to be her boyfriend and "Ultimate Neurologist" Yasuke Matsuda, Ryoko witnesses a murder committed by Junko Enoshima, before being mistaken for wanted murderer and Tragedy perpetrator Izuru Kamukura by the "Ultimate Bodyguard" Madarai octuplets. After teaming up with perverted "Ultimate Secret Agent" Yuto Kamishiro in an attempt to discover the perpetrator behind the Tragedy, Ryoko learns that she herself was personally involved in the event as the true Junko, the Junko she met having been her non-identical twin sister Mukuro Ikusaba (with whom she shared Matsuda as a boyfriend) attempting to trigger her memories, which Matsuda had been suppressing on Junkos own request both to clear her of suspicion in the events off the Tragedy, attempt to cure her depression, and test wiping the memories of others. Attempting to subdue Ryoko, Matsuda accidentally restores her memories of being Junko and his fatally stabbed, before wishing Junko success in her planned actions with Izuru and Mukuro: collapsing world society and launching a "killing game". In the 2016 video game Phoenix Wright: Ace Attorney – Spirit of Justice, the character Sorin Sprocket is eventually revealed to have anterograde amnesia, which he developed after unintentionally causing a car accident which killed his sister.
