How Does The Hippocampus Plays A Vital Role Memory...

ct There is extensive evidence to prove that the hippocampus plays a vital role in memory retrieval. However the extent to what type of memories the hippocampus supports and the process in which retrieval occurs is an ongoing debate. The two theories that are dominant in this debate are the Standard Model of Systems Consolidation (SMSC) and the Multiple Trace Theory (MTT). This paper will provide a review on the evidence supporting these two composing theories, the research providing evidence against the models, and finally their limitations. Additionally, a novel theory coined the Competitive Trace Theory (CTT) will be reviewed in order to conclude whether or not this model can provide a more holistic and accurate representation of the role of the hippocampus in memory retrieval while simultaneously providing explanations for flaws in previously proposed models. Introduction Extensive research in the field of memory and cognition have provided substantial evidence to prove that the hippocampus is a critical brain mechanism in the role of memory. Although an ongoing debate specifically in memory retrieval is the exact role of this brain structure when extracting memories. There are multiple models of the neural basis of memory retrieval that have posed a hypothesis to answer this exact question. The two theories that are dominant in this debate are the Multiple Trace Theory (MTT) proposed by Nadel and Moscovitch in 1997 and the Standard Model of Systems ConsolidationShow MoreRelatedThe Theory of Reconsolidation753 Words   |  3 PagesReconsolidation - What is it and how can it impact on our lives? Learning is a very important aspect of humans and creatures alike. Not only is it essential to the survival and adaption into this world but it also defines who we are as individuals (Schiller et al, 2010; Tronson Taylor, 2007). Memories from past experiences shape the people that we are today. A crucial element to learning is memory, without it we would not be able to retain information. The process of memory is very distinct and consistsRead MoreMemory Formation And Its Effects On The Nervous System1492 Words   |  6 Pages Memory formation takes place in the nervous system and these memories are mediated by gene expression where long-lasting changes take place between neurons in synaptic connections. In 1949, Hebb postulated, when two neurons are activated at the same time, strengthening of synaptic efficiency will result in the appropriate synapse (Lynch, 2004). Since then efforts have been channeled into understanding mechanisms responsible for synaptic strengthening refereed to as long-term potentiation (LTP),Read MoreModels Of Theories Of Memory1235 Words   |  5 Pagestheories of memory. This essay will evaluate two models of theories of memory. Memory can be defined as the persistence of learning over time via the encoding, storage, and retrieval of information. Encoding is the process of categorizing incoming information through conscious effortful processing, rehearsal, or unconscious automatic processing. The storage process involves the retention of encoded information over time. Lastly, retrieval is the process of getting information out of memory. There areRead MoreMemory And Memory Of Memory1866 Words   |  8 PagesMemory is a vital component in our body in which shapes who we are, considering the memory is where all our knowledge and past experiences are stored. As the knowledge and past experiences we gather throughout our lifetime are irreplaceable, that is why we must ensure that our memory systems are kept in perfect condition, making sure that we put effort into enhancing our memories in keeping what we cherish the most. Researchers have shown that i t is possible to use techniques to ameliorate memoryRead MoreSmell And Odor And Emotion2874 Words   |  12 Pagesbetween odor and emotion, one must define what an odor is. More than just a sense, smell consists of molecules that recognized by olfactory receptors and must have a specific concentration (Yantis, 2014). With much research, a relationship between memory and odor has existed and has led to broader findings about odor and other components. According to a 2009 study, a relationship between odor and mood exists (Croy et al., 2011). However, research done regarding odor and emotion is a fairly recentRead MoreApplication Of Type 1 Diabetes Mellitus3781 Words   |  16 PagesTable of Contents I.

This has been shown to be true on a relatively linear scale with the exception of our first three to four years of life (Fitzgerald, 1991). It is even common for adults not to have any memory before the age of six or seven. The absence of memory in these first years has sparked much interest as to how and why it happens.

In brief, the concept of homeostasis introduced by Cannon has proved to be very valuable in explaining how acute physiological stress responses to threats of survival lead toward chronic stress responses. Selye (1956) was the first investigator to use the term ‘stress’ to describe the problems associated with homeostasis identified by Cannon decades earlier
