Mind and Behaviour
Episodic memory, a type of explicit memory, includes memory for specific times, places and events that can be clearly and explicitly described. Impairment to episodic memory is one of the most common presenting clinical symptoms of Alzheimer's in its early stages. How does episodic memory function and what mechanisms are involved and affected by its dysfunction in Alzheimer's disease? Sperling et al. (2010) describe how a default network comprised of the medial temporal lobe and cortical regions are most prominently involved in memory function, in which the posteromedial cortices play a key role in the encoding and retrieval of memories. These regions are particularly susceptible to early amyloid deposition involved in the development of Alzheimer's disease (Sperling et al., 2010). Functional abnormalities in these regions have been detected through magnetic resonance imaging studies of individuals with clinical presentations of Alzheimer's disease, as well as individuals at risk of developing Alzheimer's disease, such as people with a genetic predisposition as well as elderly people that exhibit mild cognitive impairment (Sperling...
It is noted by Sperling et al. (2010) that MRI imaging revealed that the changes to these regions manifest as increases rather decreases in measured activity, which they have interpreted as demonstrated excitotoxicity leading to imminent functional failure of the neuronal networks. Furthermore, these findings may lead in the future to potential effective predictive models and treatments for Alzheimer's disease (Sperling et al., 2010).
Explicit memory is most significantly implicated in the development of Alzheimer's disease, but what about implicit memory? Contrary to explicit memory, implicit memory involves task performance outside of the realm of conscious awareness, which includes memory for how to perform everyday tasks without conscious recollection and thought regarding how…

Mind and the Brain There are several theories that have been proposed for explaining the relationship between one's mind and brain. If truth be told, it can be said that it is one of the most talked about philosophical fields. Mind vs. Brain Mind and brain are interrelated. For a majority of people, there is no difference between the two. Many scientists and philosophers hold the belief that the brain and the mind
Mind, Freedom and Knowledge Descartes argued that that all humans had both a body and mind, and that the mind was eternal while the body was subject to physical and material laws. The universe was divided between the mind and matter, and the physical world could be explained by mathematical and scientific laws. Hobbes, Locke and other political and philosophical theorists of the 17th Century were also influenced by the new
Minds and Computers Dennett explains that what a person believes must be based at least in part on something which they can ascribe to be true based on evidence that they possess. It is impossible to believe something based on nothing; even religions have certain basic facts such as the existence of known locations or even the fact that human beings exist is a fact in and of itself. When there
Mind and Behaviour Investigators in the discipline of psychology strive to determine factors that affect the mind and behaviour and how these interactions occur. In order to form hypotheses and answer questions, these scientists adhere to the scientific method. However, often psychological studies provide weak reliability and validity due to issues such as small sample sizes, inappropriate control groups or a complete lack there-of, as well as an inability to determine
Mind I may not be perfect, but I am comfortable and content in my own mind. Being comfortable with one's thoughts is the most important feature of inner peace. Struggling with thoughts brings about anxiety, unrest, and discontent. When we are able to accept feelings such as anger, resentment, self-pity, sadness, or discomfort, and allow those feelings to exist without judgment, we can become content and reach a state of mind
Behavior Therapy is generally an approach of psychotherapy which aims to treat any sort of psychopathology to eliminate undesired behaviors in a patient or subject (Masters, et. al., 1987). This type of psychotherapy is based on the learning theory. Behavior therapy generally attempts to help in solving certain behavioral problems; this type of therapy has a long history. In the early first century in Rome, Pliny the Elder was known
