What H. M. Taught Us Eichenbaum Analysis

In the article, “What H.M. Taught Us” by Howard Eichenbaum was published in the Journal of Cognitive Neuroscience for Massachuetts Institute of Technology. In his article, he discusses the findings of Suzanne Corkin and her colleagues create a great pathway for the field of psychology to get a better understanding of memory, in this case specifically through studying amnesic patients, including the well-known patient, Henry Molaison. They characterized amnesia as a selective deficit in memory, and further into the future, researchers have come to understand the functional organization of the medial temporal memory system and the functioning of its cognitive processes.
The article indicates that H.M. brought about five main findings: that memory is a “distinct psychological function”, amnesia doesn’t harm

H.M. evidently showed to have full intact memory of a normal amount of information over a brief period of time, until he was distracted by intervening mental activities such as being able to normally repeat a phone number and carry on a conversation that had no reference to the past or an event left behind the talk. Several studies support that the hippocampus is highly engaged to train information across brief periods of time and activating the hippocampus contributes to subsequent memory performance. Hippocampal activation can even predict subsequent memory during the acquisition of new information.
The evidence found for amnesia being an impairment of declarative and episodic memory is that amnesia associated with damage to the hippocampus is selective to declarative memory, for example Henry was absent of episodic memory. A core deficit in amnesia is a loss of the ability to distinct memories from one another and to relate distinct elements of memories. Unfortunately, this includes the ability to use memories in any given situation also known as relational

    When I read what happens when your hippocampus is damaged, my mind went to a movie I just watch. In 50 first dates Drew Barrymore plays a woman who can’t form new memories because she was in a crash in which she received a head injury. We can assume from the movie that she has injured her hippocampus. Since her hippocampus was damage it cause her to have ametrograde amnesia which means she can no longer make new long term memories since the crash. This is occurring because the switching station that is controlled by the hippocampus can’t make her new short term memories into long term memories.…

    The theories that have been developed by experts mostly involve the hippocampus and the essential function that it provides. Continued research on Anterograde Amnesia is important in order to gain knew knowledge about the hippocampus as well as other psychological phenomena related to anterograde amnesia, such as Alzheimer’s and retrograde amnesia. The studies presented in this paper address modern questions posed by researchers about anterograde amnesia. What has mainly been discovered is that some forms of anterograde amnesia can be treated if they are not the result of permanent brain damage.…

    Autobiographical Memory

    Our expectations, experiences, and current knowledge all affect how memories are created. Many people do not realize how flawed our memory can be. The largest component of our memory is called autobiographical memory, it is a collection of memories that can describe our past. Autobiographical memory includes both episodic and semantic memory. For example, we can remember hiking in the Smokey mountains, seeing all the trees and remembering some of the conversations we had with friends (episodic memory) ; It might also include how you traveled to the Smokey mountains (by plane or car) or a list of your hiking gear and the time of day you hiked (semantic memory).…

    Did you know that possessing a greater amount of dopamine receptors in the hippocampus results in better episodic memory? It’s a wonder why some people have great memory of past events, while others have none. As an adult it gets increasingly harder to remember events you experienced as a child. It has always been a phenomenon as to why you can’t remember the memories you had as a child. Why you forget what happens before the age of four.…

    It is not the easiest of tasks, especially for someone who suffers like H.M, however with practice people would normally improve, and that is exactly what had happened. H.M would improve each time he was asked to perform the task. This is called ‘declarative memory,’ which means, “The conscious recollection…

    In Learning and Memory, Henry Molaison, or H.M. as the psychology world knew him, also knew of his condition and the only way he could describe it was that it seemed like he was waking up everyday from a dream but couldn’t remember any of it (p.260). H.M. allowed himself to be research by the psychology world in hopes to find out the cause of short-term memory…

    Henry Molaison, known in the field of psychology as H.M., is the most studied mind in recorded history. Without studies on his brain, it is doubtful we would have any understanding in how our brains and memory operate. After cracking his skull at an early age, H.M. started to develop a tendency of seizures, blacking out, and not being able to control his bodily functions. These frequent episodes caused H.M. to drop out of high school and seek medical attention to relieve him of his suffering. Dr. Scoville, a renown neurosurgeon took on the task of removing H.M.'s hippocampus, which was associated with emotion but its function was unknown.…

    Amnesia In Memento

    In an experiment conducted by Zola-Morgan (1986), an amnesic patient named R.B. had damage to one specific region (CA1) of the hippocampus, therefore, supporting that damage limited to the hippocampus is enough to cause amnesia. This indicates that Nolan portrayed Lenny’s amnesia with a basis in creating lesions in the hippocampus and greater MTL regions, however, the severity of both Lenny’s retrograde and anterograde amnesia are contentious. A study done by Race and Verfaellie (2011) found that “the magnitude of semantic learning deficits in amnesia has been found to correspond to the amount of MTL damage.” This idea shows that Nolan inaccurately portrayed the extent of Lenny’s anterograde amnesia as his seems to be as severe as H.M.’s who had MTL region removal, whereas Lenny had a traumatic brain injury which would not have as greater MTL damage as surgical removal. Lenny is portrayed as being completely reliant on his artificial memory system and any attempts at learning new episodic or semantic memories are completely impaired to the extent that H.M. is described to be.…

    In anterograde amnesia, the formation of new memories is impaired, while in retrograde amnesia, the retrieval of previously formed memories is impaired. Research shows that anterograde amnesia results from a failure of memory encoding and storage. New information is processed normally, but almost immediately forgotten, never making it into the regions of the brain where long-term memories are stored. More specifically, in normal use, neurons in the mammillary bodies of the hypothalamus make connections with the thalamus, which in turn makes connections with the cortex of the brain, where long-term memories are stored. Anterograde amnesia can therefore result from damage to the hypothalamus and thalamus and the surrounding cortical structures, so that encoded memories are never stored since connections between hippocampus and cortex are…

    Verbal memory impairments in schizophrenia associated with cortical thinning S. Guimond, M.M. Chakravarty, L. Bergeron-Gagnon, R. Patel, M. Lepage Background Our memory is a cognitive function that we most call upon. We are constantly using our memory to store numerous amounts of information, which helps us to develop our own bank of common knowledge, which we can later call upon. We tend to consider memory as a whole, when in fact the type of information we memorize and recall, actually engages our brain in different ways.…

    Tulving’s persuasive theory of the two propositional memory types: Episodic and Semantic, have been pivotal in the research and study of Long-Term Memory for over four decades (Brown, Creswell, & Ryan, 2016). Semantic memory provides us with the memory needed for the use of language, whereas episodic memory focuses on the autobiographical events that can be explicitly recalled. There are many differences in these two memory sub-types that further differentiate them from one another. In addition to the differences between these two declarative memory types, we will also discuss the evidence for the distinction between episodic and semantic memory, both behaviorally and with the brain. Episodic memory is a type of memory that is associated…

    The 2004 movie 50 First Dates is a romantic comedy about a woman named Lucy who wakes up every morning believing it is October 13, her father’s birthday. After a traumatic brain injury resulting from a car accident, Lucy suffers from a fictional amnesia called Goldfield’s Syndrome. Although there are elements of truth in Lucy’s amnesia, her symptoms are ultimately a poor depiction of amnesia and the movie contains many factual inaccuracies about memory. This paper will analyze the cause, symptoms and treatment of Lucy’s amnesia and compare her experience to what is known about amnesia from neuropsychology.…
