Problem: Morbid Angel is an American death metal band based in Tampa, Florida formed in 1983 by guitarist and sole remaining original member Trey Azagthoth, vocalist and bassist Dallas Ward, and drummer Mike Browning. Widely considered as one of the most influential bands in the genre and important in the transition of death metal from its thrash metal roots, they were one of the first bands to incorporate guttural vocals, up-tempo blast beats, multiple tempo changes and dark atmosphere. They have been described as one of "the most influential and emulated bands in death metal", alongside Obituary and Cannibal Corpse, and have been cited as an influence by many later bands. They were also the first death metal band to experience mainstream success in connection with being signed to Giant Records in 1992, heavy rotation of their music videos on MTV, and having the music video for the song "God of Emptiness" shown on an episode of Beavis and Butt-head.

1991 saw the release of their second album, Blessed Are the Sick, which was met with widespread critical acclaim, and is considered by many to be a landmark release in the death metal genre. The album differed from its predecessor, showcasing a more "sludgy" side to the band. Following the success of Altars of Madness' and 'Blessed are the Sick', in the Spring of 1992 Morbid Angel were signed by Irving Azoff to Giant Records for one album, with the option of five more. Later that same year, second guitarist Richard Brunelle was kicked out of the band due to alleged substance abuse. On June 22, 1993 the band released their third full-length album 'Covenant', which went on to sell over 150,000 copies in the United States alone. Their record label dedicated promotional resources to the album, and commissioned music videos for the songs 'Rapture' and 'God of Emptiness'. These music videos were put on heavy rotation by MTV, and the latter also appeared on the television show Beavis and Butt-head. The success of the album enabled the band to tour with Black Sabbath and Motorhead across the United States from February through March of 1994, which David Vincent credits with helping the band significantly expand their audience. The band released its fourth studio album, Domination, on May 9, 1995, which featured new guitarist Erik Rutan of Ripping Corpse. It proved to be a somewhat controversial album among fans, featuring a slower, more atmospheric and experimental sound than on previous albums. Music critic describes the album's sound as "more groove-oriented". The album has gone on to sell over 100,000 copies in the United States alone. Regardless, following the release of the album their record label dropped them from their roster.

Problem: Henry Gustav Molaison (February 26, 1926 - December 2, 2008), known widely as H.M., was an American memory disorder patient who had a bilateral medial temporal lobectomy to surgically resect the anterior two thirds of his hippocampi, parahippocampal cortices, entorhinal cortices, piriform cortices, and amygdalae in an attempt to cure his epilepsy. Although the surgery was partially successful in controlling his epilepsy, a severe side effect was that he became unable to form new memories. H.M. was widely studied from late 1957 until his death in 2008. His case played an important role in the development of theories that explain the link between brain function and memory, and in the development of cognitive neuropsychology, a branch of psychology that aims to understand how the structure and function of the brain relates to specific psychological processes.

Henry Molaison was born on February 26, 1926, and experienced intractable epilepsy that has sometimes been attributed to a bicycle accident at the age of seven. (This accident was initially reported to have occurred at age nine, but was corrected by the patient's mother at a later stage.) He had partial seizures for many years, and then several tonic-clonic seizures following his 16th birthday. In 1953, he was referred to William Beecher Scoville, a neurosurgeon at Hartford Hospital, for treatment. Scoville localized Molaison's epilepsy to his left and right medial temporal lobes (MTLs) and suggested surgical resection of the MTLs as a treatment. On September 1, 1953, at the age of 27, Molaison's bilateral medial temporal lobe resection included the removal of the hippocampal formation and adjacent structures, including most of the amygdaloid complex and entorhinal cortex. His hippocampi appeared entirely nonfunctional because the remaining 2 cm of hippocampal tissue appeared to have atrophied and because the entire entorhinal cortex, which forms the major sensory input to the hippocampus, was destroyed. Some of his anterolateral temporal cortex was also destroyed. After the surgery, which was partially successful in its primary goal of controlling his epilepsy, Molaison developed severe anterograde amnesia: although his working memory and procedural memory were intact, he could not commit new events to his explicit memory. According to some scientists, he was impaired in his ability to form new semantic knowledge, but researchers argue over the extent of this impairment. He also had moderate retrograde amnesia, and could not remember most events in the one- to two-year period before surgery, nor some events up to 11 years before, meaning that his amnesia was temporally graded. However, his ability to form long-term procedural memories was intact; thus he could, for example, learn new motor skills, despite not being able to remember learning them. The case was first reported in a paper by Scoville and Brenda Milner in 1957. Near the end of his life, Molaison regularly filled in crossword puzzles. He was able to fill in answers to clues that referred to pre-1953 knowledge. For post-1953 information he was able to modify old memories with new information. For instance, he could add a memory about Jonas Salk by modifying his memory of polio. He died on December 2, 2008.

Did he ever get any better from the operations?
