A new bride suffers retrograde amnesia after a traumatic brain injury and loses the memory of ever having met her husband in this romantic drama based on actual events. Paige suffers a traumatic brain injury in a car accident that results in retrograde amnesia. She awakens in a hospital room having lost several years of her life, and the memory of ever having met Leo and marrying him. Leo attempts to remind Paige of their relationship and reclaim their life prior to the car accident. Although Paige never regains her memory, she discovers facts of her past that lead her back to her life prior to the accident.…
Amnesia comes in many forms, ranging from the dissociative to that caused by physical damage to the brain (“Amnesia”, “Mayo Clinic ”). Neurological amnesia becomes more common as people age, due to the onset of Alzheimer’s disease and other forms of neurological deterioration, although it also affects other age groups through means other than the regular deterioration of the brain. Dissociative amnesia, however, affects each demographic equally, and has no particular bias (“Dissociative Amnesia”, Mayo Clinic, “Amnesia”). Neurological amnesia can afflict any person with brain damage to the hippocampus or other memory forming regions of the brain (“Amnesia,” Mayo…
Moreover, the hippocampus continued to shrink in the 12 years of follow-up in the study (Geddes, Xu-Feng, Newell…
My best friends invite me over for pizza and a friendly game of cards. As I am enjoying my evening eating pizza, socializing, and playing cards, certain parts of my brain are involved which allow me to perform properly. The limbic system comprises of the thalamus, hypothalamus, hippocampus, amygdala, and the cingulate cortex. In general, the limbic system is involved in emotions, motivation, memory, and learning.…
Internally Generated Cell Assembly Sequences in the Rat Hippocampus (Summary) It was long thought that the hippocampus was the seat of spatial navigation. However, newer models suggest that other cognitive processes such as episodic memory and action planning depend on the hippocampus. Further, these models suggest that this activity might be internally organized cell assemblies.…
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.…
The Hippocampus is a part of the brain in the Limbic System. This part is where long-term memory is stored. If this part becomes dysfunctional in any given person, he or she will be unable to form long-term memories. Therefore, that person will only have short term memory that will not change to long-term during sleep, so he or she will lose any new memories gained throughout the day. A case study that was done on this phenomenon in the 1950’s was done on Henry Molaison.…
Amnesia is most frequently caused through some form of brain damage. Sometimes it is caused by outside factors, such as injury to the head, use of certain drugs, or illnesses which affect the brain. These may include strokes, heart attacks, brain inflammation, and degenerative brain diseases (namely Alzheimer’s). However, Amnesia may also be caused by the brain itself. This is called psychogenic amnesia.…
The information in the movie has been used incorrectly in some cases, but the movie provide some truth information in physiological way with that said the movie also includes psychological concept and depict. The movie has provided information, which is inaccurate because people who suffer from amnesia do not usually forget themselves every morning, but in the beginning of the movie it shows that the main character Christina doesn’t know herself. “Anterograde amnesia is the inability to remember events and experiences that occur after an injury or the onset of a disease” (Feist and Rosenberg, 279). Furthermore, for the accurate information director Rowan joffe has used the physiological behavior of a person when she looses her memories. For example, to use this concept as a memory, Christine waking up every morning, not remembering anything, who she’s with, where she is and who’s the person that next to her.…
The temporal lobe epilepsy is often associated with memory disfunctions, because hippocampus is one of the most frequent epileptogenic areas. Approximetly 60 to 70 % of the adult epileptic patients are affected by temporal lobe epilepsy.…
The hippocampus is belongs to the limbic system and it is located in the medial temporal lobe of the brain (Squire & Zola-Morgan, 1991). It has the function of regulating the emotions of individual and also plays an important role in spatial navigation. Besides that, hippocampus plays an important role in the storage of both explicit and declarative memories. Therefore, it is being described as the conscious recall of facts and events (Eichenbaum, 1999; Maguire, Burgess & O’Keefe, 1999; Squire, 1992, cited in Rubin, 2015). Also, hippocampus plays an important role in memory process.…
Although the characters in 50 First Dates claim that Lucy’s long term memory is fine, Eichenbaum (2013) states that amnesia is an impairment of declarative long term memory, which includes both episodic and semantic memory (p. 16). Amnesic patients with different injuries can experience different symptoms related to different types of long term memory; the case of K.C., who has no autobiographical memory but does know semantic facts related to his life, exemplifies this (Kolb & Whishaw, 2015, p. 487-488). Episodic memory, or autobiographical memory, is related to a person’s own life experiences (p. 486). Patients with damage to the hippocampus, part of the temporal lobe, have difficulty with daily life because they lack episodic memory and an awareness of self (p. 487). Lucy’s autobiographical memory seems to function appropriately for at least the length of the day, as she can maintain a sense of continuity and recalls events from before her accident.…
Since Lucy damaged her hippocampus embedded within the temporal lobe in the accident, she cannot make new memories. She clearly remembers everything else that happened in her life before the accident. Her long term memories before the accident are intact which relates to anterograde amnesia where individuals are able to recall events that are already in the memory that happened prior to the specific accident(Mastin). In this case of anterograde amnesia, At night, all the memories Lucy obtained that day disappears and she starts with a new, clean slate the next day. She thinks every day is her father’s birthday…
Episodic memory refers to specific events in someone’s memory that have occurred in the life of the individual, whereas Semantic memory refers to the knowledge about the world, facts, general knowledge that does not directly relate to a person, but could still be a part of their life experience. Semantic memory usually doesn’t involve the role of the amygdala, because it is facts and figures. In episodic memory, the amygdala plays the role of adding an emotional aspect to the memory. . Figure2 Leonard Shelby could be compared to the case of H.M. H.M’s case led to the discovery that the hippocampus is not the place of permanent memory storage, but does played a role in the transfer of information (memories) from short term into long-term memory. Because of the lack of transfer from short term to long term, sufferers may therefore repeat comments or questions several times and forget people who they met after the trauma in a matter of minutes, as Shelby does numerous times throughout…
Introduction The number of adults over the age of 65 in the United States has drastically increased in the last few decades. In 1970, 9.8% of the United States population was 65 and older, in 2010 13%, and by 2030 more than 20% of the United States population is projected to be 65 years of age and older (Ortman, Velkoff, & Hogan, 2014). Consequently, the problems and challenges of aging are an important societal concern. Age-related normal and pathologic cognitive changes have been well documented in the scientific literature (Harada, Natelson Love, & Triebel, 2013); and while researchers have devoted effort investigating the how’s and why’s of age-related changes in memory processes, limited research has investigated how aging-related memory changes effects judgment and decision making (J/DM; Del Missier, Mantyla, & Nilsson, 2015).…
