Memory and the Brain Essay

Memory is divided into three categories. These categories consist of: sensory memory, short term memory and long term memory, out of these short term memory is the main focus in this essay. It has been widely researched due to interest of how much memory can be stored, how long this memory can be stored for and what information is memorised.

Memory is not located in just one spot of the brain, but it is a brain wide process, in which

Memory refers to the persistence of learning in a state that can be revealed at a later time (Squire, 1987). A memory is a network of neocortical neurons and the connections that link them. That network is formed by experience as a result of the concurrent activation of neuronal ensembles that

Memory is the retention of information over time and it changes through our lifespan, from infancy through adulthood (Santrock 218). There are two types of memory, explicit and implicit.

Memory is a set of cognitive processes that allow us to remember past information (retrospective memory) and future obligations (prospective memory) so we can navigate our lives. The strength of our memory can be influenced by the connections we make through different cognitive faculties as well as by the amount of time we spend devoting to learning specific material across different points in time. New memories are created every time we remember specific event, which results in retrospective memories changing over time. Memory recall can be affected retrospectively such as seeing increased recall in the presence of contextual cues or false recall of information following leading questions. Memory also includes the process

A part in the brain called hippocampus is very important to memory. Hippocampus is the vital key to remembering and it is also vital to emotions. It also helps you make new memories so you aren’t just remembering the past. The cerebral cortex is also very important. It helps you do things without you thinking about them. Examples of what the cerebral cortex does is breathing, how to swallow, or to catch yourself before you

The hippocampus collects different bits of information that affect the senses and puts all of it into an event of a memory. In the Working Memory, it quotes, “The hippocampus is where the vast amount of knowledge you have acquired over your lifetime is housed for long-term storage.” Page 6. When the hippocampus collects different information and holds it for use at any time later in life. Said in the Working Memory…, “The PFC is the home of working memory. Located in the front of the brain, the PFC coordinates with other areas of the brain through electrical signals and receives information from those regions so your working memory can make use of it.” Page 6. Partial Frontal lobe is controlled other parts of the brain and sends signals and take in information, so it gets saved in your memory. This is important for long-term memory is used in further or moderately in life. “The amygdala is the brain’s emotional center. When you are experiencing a strong emotion, like fear, your amygdala is activated.” Quoted by the Working Memory…, page

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

Do you ever wonder how you remember events from your childhood or basic tasks like how to tie your shoe? The answer is quite simple: long-term memory. It is said that long-term memory has unlimited capacity and storage time. Long-term memory is organized into two different categories. The first category is explicit memory, which contains memories that are consciously retrieved (i.e. trivia facts and personal milestones in life). The second category of long-term memory is implicit memory, and is comprised of unconscious recollections like habits and phobias. There are various sections of the brain that are responsible for long term memory. The basal ganglia and cerebellum

Memory consolidation is a process of gradual stabilization that new memories must undergo in order to persist (Müller and Pilzecker, 1900). In the case of declarative memories (or explicit learning), consolidation initially takes place within the hippocampus before these memories become permanently stored within the neocortex. Evidence for this time- and region-dependent systems consolidation has been demonstrated by lesion and imaging studies in primates and rodents indicating that recent memories are stored within the hippocampus, whereas remote memories are stored in the neocortex (McClelland et al., 1995; Squire and Alvarez, 1995; Frankland and Bontempi, 2005).

The generally accepted classification of memory is based on how long you can remember an item or experience (memory retention), and identifies three types of memory: sensory memory, short-term memory, and long-term memory

Memory is defined as "the persistence of learning over time through the storage and retrieval of information." Our memory can be compared to a computer's information processing system. To remember an event we need to get information into our brain which is encoding, store the information and then be able to retrieve it. The three-stage processing model of Richard Atkinson and Richard Shiffrin suggests that we record information that we want to remember first as a fleeting sensory memory and then it is processed into a short term memory bin where we encode it ( pay attention to encode important or novel stimuli) for long-term memory and later retrieval. The premise for the three step process is that we are unable to focus on too much

Memory makes us. It is, to an extent, a collection of unique and personal experiences that we, as individuals, have amassed over our lifetime. It is what connects us to our past and what shapes our present and the future. If we are unable remember the what, when, where, and who of our everyday lives, our level of functioning would be greatly impacted. Memory is defined as or recognized as the “sum or total of what we remember.” Memory provides us the ability to learn and adjust to or from prior experiences. In addition, memory or our ability to remember plays an integral role in the building and sustaining of relationships. Additionally, memory is also a process; it is how we internalize and store our external environment and experiences. It entails the capacity to remember past experiences, and the process of recalling previous experiences, information, impressions, habits and skills to awareness. It is the storage of materials learned and/or retained from our experiences. This fact is demonstrated by the modification, adjustment and/or adaptation of structure or behavior. Furthermore, we as individuals, envision thoughts and ideas of the present through short-term memory, or in our working memory, we warehouse past experiences and learned values in long-term memory, also referred to as episodic or semantic memory. Most importantly, memory is malleable and it is intimately linked to our sense of identity and where we believe we belong in the world.

In general, there are three types of memory: sensory memory, short-term memory and long-term memory. Sensory memory, by definition, is the preservation of information in its original sensory form, for a fraction of a second. This means that when you smell, touch and/or see anything, the impression of the occurrence will last for a couple of moments. This

C. In general, the brain's system for creating and using memories is very effective, but problems often occur.
