Hi, I am looking for someone to write an article on brain damage Paper must be at least 2250 words. Please, no plagiarized work! However, it led to a critical condition whereby HM faced a dense memory loss (Schaffhausen, 2007). The surgeon realized his patient had become amnesic and referred him to another neurosurgeon Wilder Penfield and neurophysiologist, Brenda Milner (Schaffhausen, 2007). It was after a detailed examination that it dawned to them that, the removed hippocampus was essential for the creation of memories. Consequently, prompted scientists then to publicize this information with the intention of creating awareness aimed at preventing the occurrence of the same procedure. HM had lost his ability to create new memories, he lacked the ability to consolidate any new information that he was exposed to. It was however intriguing that he had retained memory on things that he had learnt during the 27 years before the operation (Plotnik & Kouyoumjian, 2011). Surgeons concluded that HM was suffering from anterograde amnesia, which refers to a condition where damage to the brain affects the storage of new information just after the damage (Plotnik & Kouyoumjian, 2011). This was evident from the fact that HM could recall events just before the trauma and not afterwards. Following the observations on HM, it will be inappropriate to claim that the medial temporal lobes are the principal sites of memory. This is because he had retained other forms of memory such as short-term memory. Therefore, researchers concluded that there were a variety forms of memory. They also concluded that different parts of the brain regulated these respective memory forms.

HM could not have retained his long-term memory as well as the short-term memory if indeed the medial temporal lobes were the principal part of memory. This inspired scientists to investigate how the brain worked regarding retaining memory. The human brain is three times that of other mammals besides having a more complicated structure of living systems. The brain is approximately 1.5 kg in weight, soft and&nbsp.pinkish in colour as well as little white in the interior. The pinkish outer layer also goes by the name grey matter, which turns into grey once a person dies. The interior contains many structures responsible for communications [purposes as well as interpretation. The pinkish outer layer takes charge of computation factors as well as thinking problems.&nbsp.
