1. Describe anterograde and retrograde amnesia, as well as Alzheimer’s disease. Provide a detailed response.

Anterograde and Retrograde amnesia, are the two main types of amnesia. Although they are opposite of each other, they are as equally devastating the individuals affected by them. The first of the two I’ll be talking about is anterograde amnesia, anterograde meaning after, is the form of amnesia where you can't form new memories or in proper terms you are unable to use or have lost use of your hippocampus the organ in your brain that is responsible for converting short-term memory to long-term memory. There are many causes for this type of amnesia, generally it is caused by some sort of injury to the brain like, head trauma, illnesses, alcohol intoxication, or even can be due to surgery complications. However, people with anterograde are able to maintain their memories from before the trauma causing the …show more content…

Describe the case of Henry Molaison, also known as H.M. What did H.M.’s case tell psychologists about the role of hippocampus in memory? Identify the role of two of these structures in memory: the cerebellum, the amygdala, and the prefrontal cortex.

At the age of ten Henry Molaison started suffering from epilepsy after an accident on his bicycle when he was seven. He’s condition got worst with age and he was unresponsive to his Antseizure medications. Debilitated by his conditions he was despite for a solution at in 1953, at 27 he agreed to an experimental surgery. That would remove parts of his brain, his temporal lobes which include his hippocampus. Amazingly enough the surgery did work his epilepsy was repressed! However, the surgery cause him to suffer from anterograde amnesia as a result of the remover of his hippocampus. He also suffered from a mild case of retrograde amnesia as a result of the surgery. Despite all the complications H.M. manage to perform normally on a multitude of different tests and could still recall distant

  • Significant Role of the Hippocampus

    1158 Words  | 3 Pages

    Hippocampus is a small, curved region, which exists in both hemispheres of the brain and plays a vital role in emotions, learning and acquisition of new information. It also contributes majorly to long term memory, which is permanent information stored in the brain. Although long term memory is the last information that can be forgotten, its impairment has become very common nowadays. The dysfunction is exemplified by many neurological disorders such as amnesia. There are two types of amnesia, anterograde and retrograde. Anterograde amnesia is inability in forming new information, while retrograde refers to the loss of the past memory. As suggested by Cipolotti and Bird (2006), hippocampus’s lesions are responsible for both types of amnesia. According to multiple trace theory, the author suggests that hippocampal region plays a major role in effective retrieving of episodic memory (Cipolotti and Bird, 2006). For example, patients with hippocampal damage show extensively ungraded retrograde amnesia (Cipolotti and Bird, 2006). They have a difficult time in retrieving information from their non-personal episodic events and autobiographical memory. However, this theory conflicts with standard model of consolidation. The difference between these theories suggests that researchers need to do more work to solve this controversy. Besides retrieving information, hippocampus is also important in obtaining new semantic information, as well as familiarity and recollection (Cipolotti and Bird, 2006). For instance, hippocampal amnesic patient V.C shows in ability to acquire new semantic knowledge such as vocabularies and factual concepts (Cipolotti and Bird, 2006). He is also unable to recognize and recall even...

Although he had a history of mental illness, Kazmierczak had been given the Dean’s Award, the highest honor an undergraduate of NIU can receive, attended graduate school at the University of Illinois at Urbana-Champaign, and sought counseling for his mental illness. From the outside, it appeared that he had taken control of his life, described as “being so nice he must be a mass murderer” by faculty members at NIU. To say the least, his killing spree and subsequent suicide came as a shock to those who knew him, and it is difficult

    One cause is benzodiazepine drugs, which are known to have powerful amnesic affects. This has also been recorded in non-benzodiazepine sedatives which act on the same set of receptors. Another cause is a traumatic brain injury in which damage is usually done to the hippocampus or surrounding cortices. It can also be caused by shock from psychological trauma or an emotional disorder. Illness, though much rarer, can also cause anterograde amnesia such as encephalitis, which is the inflammation of brain tissues do to some foreign pathogen. Lucy is diagnosed as having Goldfield’s Syndrome, which is the exact same thing as anterograde amnesia.

    Therefore, they summarize that the reason why Clive suffers in the Amnesia is caused by the hippocampus is not affected. The Hippocampus is a structure that is located inside the temporal lobe, and that is a part of the limbic system. The function of the Hippocampus is similar to a post office used for encoding, storage and recalling memories, all presenting information would first remain, analysed and encoded in the Hippocampus then transmit them to different areas of the brain. In other words, Clive is unable to encode memory and hold information which is currently aware, and it is difficult to form new long-term memory such as explicit and semantic memory. Clive Wearing, now 78 years old, still cannot recover from the anterograde amnesia, he becomes a man who has the shortest memory in the world.

  • Memory And Long-Term Memory: Different Types Of Memory

    Amnesia, a severe long-term memory loss disease, is caused by damaged brain tissue. There are two different types of amnesia. Retrograde amnesia is also known as backward moving. This is when you have a hard time remembering the past, especially episodic memories. This occurs because of memory consolidation. Memory consolidation is the process of a new memory setting until it becomes permanently in the brain. If this process is disrupted, the memory may be lost (Hockenberry and Hockenberry page 265). Anterograde amnesia is also known as forward moving. This is when you are unable to form new

  • Declarative Memory Essay

    1877 Words  | 4 Pages

    The question then becomes whether declarative and non-declarative memory are in fact separate or different manifestations of the same neural process. From research on H.M., we find evidence for the existence of a declarative memory system that is independent of non-declarative memory and other forms of intelligence. H.M. had the capacity to hold information in his head for a period of time, suggesting that his working memory was intact (Squire and Wixted, 2011). Further evidence that not all memory is the same is the fact that H.M. acquired a motor skill despite not being able to remember actually learning the skill, thus showing the difference between episodic and semantic memory. Amnesiacs are able to acquire the perceptual skill of reading mirror-reversed words at a normal rate compared to controls (Cohen and Squire, 1980), demonstrating that the ability to learn new perceptual skills also remains intact. Of the forms of non-declarative memory, procedural memory involves the cerebellum, motor cortex, and basal ganglia (General Intro the Neurobiology…). Thus, non-declarative memory can, in a way, be seen as a more primitive form of memory that is not acquired through the integration and consolidation of neural events in the medial temporal lobe, but rather through learned associations outside of the

    As brain systems begin working, memory also starts to work. (4). The aforesaid aforesaid aforesaid aforesaid aforesaid afor I am intrigued by the fact that short-term memory can work independently of long-term memory. While long-term memory can be achieved through the repetition of a fact that is in the short-term memory, it appears that in amnesiac patients their long-term memory tends to return faster than their short-term memory. They can remember their favorite childhood food, but cannot remember why they are in the hospital.

  • Formation Of False Memories

    482 Words  | 1 Pages

    Have you ever been an eyewitness at the scene of a crime? If you were, do you think that you would be able to accurately describe, in precise detail, everything that happened and remember distinct features of the suspect? Many people believe that yes they would be able to remember anything from the events that would happen and the different features of the suspect. Some people, in fact, are so sure of themselves after witnessing an event such as this that they are able to testify that what they think they saw was indeed what they saw. However, using an eyewitness as a source of evidence can be risky and is rarely 100% accurate. This can be proven by the theory of the possibility of false memory formation and the question of whether or not a memory can lie.

    Henry Molaison or known as HM contributes to the deep understanding of memory by previous scientists and until now. His case had been a huge research and discussions among the well known scientists during his time and these results in the study of memories. Henry Molaison is living with a severe epilepsy where he need to undergo a surgery as medications were no longer gave him effects for his disease. So, his surgeon William Beecher Scoville suction out both of his hippocampus and when he got recovered from the surgery, his doctor realised that, Henry was having amnesia and seek him for another doctor. What confusing the doctors is that, even though the surgery was a success where Henry seizures decreasing; he is now facing dense memory loss. Then, once it was realized that the hippocampus plays a crucial roles for memory; the surgery of removing hippocampus was then banned for all and this brings to deep study of memory and hippocampus.
