H. M.: The Separation Of Declarative Memory

Clive Wearing suffers from aterograde amnesia as well as retrograde amnesia. This means that he can not create new memories and lost all of the old ones he had. About 30 years ago he had gotten a herpes virus that attacks your nervous system. This illness has impacted his life in several ways. He became so ill that he can no longer form any type of memories except for realizing who his wife is, knowing his children, and piano playing. His memory was said to last anywhere from 7 to 30 seconds at most. His wife said while eaing he forgot what he had within the short span of time that it took his fork to reach his mouth. He could not link the taste of food with the name because he suddenly forgot everything. It was like starting over every 30

The patient is a 59-year-old right-handed white female who was admitted in June to Portsmouth Regional Hospital for what was determined to be either transient global amnesia or complicated migraine. I did review those notes. She was seen by Galina Simkin, MD. The symptomatology discussed in the H&P is consistent with transient global amnesia. She was having problems asking questions inappropriately, repeating sentences, repeating questions over and over again, and seeming somewhat confused. There were no other neurological symptoms at that time. No evidence for seizure activity. No evidence for stroke. She was brought to the emergency room, where she underwent a CAT scan, which was

In Chapter 12 of The Man Who Mistook His Wife for a Hat, Mr. William Thompson suffered from an extreme case of Korsakov’s, also known as Wernicke-Korsakoff syndrome (Sacks, 1985, p. 109). According to Anderson (2010), Korsakoff syndrome can cause serious damage to one’s hippocampus and temporal lobe due to habitual alcoholism, resulting in amnesia (p. 201). Similar to HM (Anderson, 2010, p. 200), Mr. Thompson suffered from anterograde amnesia and could remember nothing for more than a few brief moments (Sacks, p. 109). Anderson (2010) states that anterograde amnesia results in the incapability of creating new memories, leading to fractional or absolute inability to remember something that just happened (p. 201). Yet, one’s long-term memories before the incident remain intact; such as when Mr. Thompson recognized his younger brother, Bob, as he walked by the window (Sacks, 1985, p. 112-113). Mr. Thompson and HM both suffered from anterograde amnesia and could remember some long-term memories but not remember new ones, signifying that the neural makeup involved in making fresh memories are diverse from maintaining past memories (Anderson, 2010, p. 202).

Salvador Dali’s 1931 painting The Persistence of Memory is a hallmark of the surrealist movement. Dali famously described his paintings as “hand-painted dream photographs” and The Persistence of Memory is a prime example of that description. The Persistence of Memory depicts striking and confusing images of melting pocket watches and a mysterious fetus-like structure all sprawled over the dreamscape representation of Dali’s home of Port Lligat, Spain. Dali uses strange images, color, and shadows in The Persistence of Memory to convey an abstract view on dreams, time, and reality.

medications do not cure the disease. It is documented that once the memory is lost, it cannot be

Recollecting some of life’s experiences can be done very accurately at times where we can depict details even after a long period of time. For patient H.M. this is the exact case. Patient H.M. suffered from severe anterograde amnesia. Anterograde amnesia patients quite often show normal memory for events that have occurred prior to the incident. Therefore, making it extremely difficult to recall or store information after the incident has occurred. H.M. had been knocked down by a bicycle at the age of 7, began to have minor seizures at the age of 10, and had major seizures after the age of 16. Patient H.M. had brain surgery in the early 1950’s around the time he had been 27 years old. The surgery had been done to alleviate severe symptoms

The Impossible Knife of Memory, by Laurie Halse Anderson is about a father-daughter duo who were trying to live a normal life so Hayley Kincain, the daughter, could finish her last year of highschool. Hayley’s father, Andy Kincain, was a veteran soldier who suffers PTSD from his active-duty days, and now currently is an alcoholic who has difficulty holding onto a steady job. Hayley constantly worries about her dad, as she inspects his truck’s mileage daily to see if he has gone to work, and skipping school to check up on him when she heard that Andy’s ex-girlfriend, Trish, has been contacting the school. Somehow, past all the panic and worry, Hayley manages to develop a close and stable friendship with her neighbor, Gracie Rappaport, who

No treatment is needed for transient global amnesia. It resolves on its own and has no

The Evidence for the Existence of Multiple Memory Systems Memory forms an important part of cognitive psychology and has been of interest to numerous psychologists. This essay is going to refer specifically to the information-processing model of memory and will discuss the experimental evidence that exists for multiple memory systems. The multi-store model of memory was first developed by Atkinson and Shiffrin (1968) and Waugh and Norman (1965).[1] It comprises sensory stores, short term-store and long-term store to form a model of memory and information processing. One component of the system is the sensory register, where our feature detection and pattern recognition processes produce a

Brain injuries, though more common than one might think, don’t always lead to serious damage for a lifetime. Even less likely was Henry Molaison, who became one of the world’s most famous brain patients after the removal of his hippocampi in order to stop his constant and severe seizures destroyed his ability to create memories.

His explicit long-term memory was mainly affected. Meaning that his mind without a hippocampus was only able to make “initial impressions” hindering him from keeping the memories for long period of time and the memories would simply just disappear (Kean, 2014). This is why he was unable to remember specific facts, events and what made him “Unable to form new memories”(Kean, 2014). The surgery also affected H.M.’s short-term memory. He was able to “Remember a random numbers for 15-minutes”, with the use of rehearsal this task would lengthen his short-term memory but he would forget that the task had even taken place 5-minutes later (Kean, 2014).

When speaking about memory, one needs to look at the parts of the brain that are

I find that how there are so many types of memory lost in Chapter 8 pg 374. To understand the nature of memory changes, one must consider they our memory is a traditionally viewed in three differently sequential components which are Sensory Memory, Short -Term Memory (also called working memory), and Long-Term Memory. It’s funny how both sensory memory and short-term memory show virtually no waking in middle age, where as on then other hand Long-term memory declines for some people. From what I’ve read it sounds like our memory declining in middle age for us are relatively and most can be compensated for it by various cognitive strategies. In order for us to recall information we often use Schemas which are organized bodies of information stored

Taylor Burroughs Dr. Craig Wilson Philosophy Online October 7, 2016 On the Problem of Identity Who am I? What a broad question to ask. We can describe ourselves by our interest, our relationships, our careers, our educational achievements, and so on. The problem with describing who we are is that we change all the time.

Case 1 tells the story of Henry Molaison (HM), a man with no memory. He lost his memory due to the operation of suctioned out the hippocampus to treat his epileptic seizures. At that time, it was not known yet that the hippocampus was essential for making memories. After operation, his seizures were significantly reduced, but Henry suffered a global amnesia. Owen et al. (2007) describes patients with global amnesia as perceptive and attentive but with a total loss of short-term memory and some trouble accessing memories of the recent past. Henry could not learn new things as he quickly forgot everything that he had learned. He could learn at a subconscious level only.
