Review of “Amygdala activity at correlated with long-term, free recall of emotional information” This article reviewed an experiment that tested the role of the amygdala in emotional memory. To be specific it hypothesized that if the amygdaloid complex (AC) was primarily involved with the formation of long-term memory during emotionally arousing situations, then the PET analysis would reveal AC activity related to retention of the relative emotional, but not relatively neutral, films.
The experiment used eight right-handed male subjects between 20 and 24 years old. While at first it was not clearly stated why the subjects used were all the same, but women, left-handed people, and subjects of differing ages were purposely omitted in favor of right-handed males of a specific age for use as a control. These subjects were shown two videos, one with emotionally neutral film clips (N) and one with emotionally arousing film clips (E).
Each video contained 12 clips. The subjects were asked to rank each film on the basis of emotionality from 0 (being the lowest) to 10 (being the highest.) The videos were also ranked on how well the subject understood each film on a scale from 0 to 10. The E and N films did not differ in their level of understandability. The films were ordered in such a way that it would maximize the chances of detecting glucose differences between E and N sessions. Since positron emission tomography was used, this was a good idea because most of the measured activity would relfect the first 15-20 minutes of tracer reuptake. Three weeks after the experiment, the subjects were asked to recall as many film clips as possible from both film sessions. As expected the E films were ranked significantly higher than the N films. The subjects could also recall more E films than N films when asked three weeks after the experiment. The scientific paper presents simple, but effect, graphs showing the discrepancies between the ratings of E and N films as well as the number of N and E films recalled. The major finding of the study pointed to the right AC in which activity during E films could be linked to memory of the E films.
The Term Paper on Existentialism In Film Subject Matter
EXISTENTIALISM IN FILM I could not say where or how existentialist themes first emerged in film. Often times, critics will point to the work of Ingmar Bergman and Federico Fellini as early examples. Indeed, these two men are titans in their art, and they will be discussed in this essay. However, it occurs to me that a certain genre of film being made in America during the late forties and early ...
Although Figure 2 was somewhat confusing to the readers, Figure 3 clearly shows a scatterplot relationship that existed between number of films recalled and right amygdala glucose levels in E films with no apparent relationship existing between those two in N films. The experimenters then offer possible explanations as to why the asymmetries between the right and left amygdalas may have occurred, but each of the explanations supported the authors’ hypothesis. Because of this fact, the explanations may have been somewhat biased or some explanations may have been purposefully ommitted. Although this may have been biased, the experimenters did not fail to mention that other parts of the brain were associated with memories of emotional nature, without having any apparent role in the formation and retention of neutral memories. Overall, the results supported the hypothesis that the amygdala plays a significant role in the free recall of emotional activities, but not neutral activities. The experimenters clearly presented the information in the scientific paper with only a few confusing spots. As stated earlier, they failed to state why eight male right-handed subjects were used. The experimenters also didn’t test “positive” emotional clips; they only tested “negative” emotional clips. This may have changed the findings if this had been done. Another weakness of the experiment was not stating how the subtraction method worked, making it hard to follow some parts of the paper.
The Term Paper on Going On Instinct Gendering Primatology In Film
Going on Instinct: Gendering Primatology in Film Melinda Kanner dwells on popular construction of primatology by the example of the films Instinct (1999) and Gorillas in the Mist (1988). The author is concerned with the question of how cultural preoccupations and tensions are revealed in [these] creations of essentially new versions of professions (Kanner n.p.) as the practices of medicine, ...
