Damage to Daves Frontal lobe Damage to Dave 's frontal lobe could be having an impact on his cognitive function with deficits in the areas of memory, social skills and attention. Stuss (2011) states that memory is one of the functions of the frontal lobe; it could be the case that Dave’s injury has affected his procedural memory. Furthermore Vecera and Rizzo (2004) argue that social attention involves frontal lobe processes such eye gaze cues to allocate attention, again damage to this area of the brain suggests an effect on Dave’s social skills. Westen, Burton and Kowalski (2005) explain that the action of focusing ones conscious awareness is called attention, in Dave’s case where he bursts into tears or becomes very angry during rehabilitation could be due to him not being able to focus on the tasks at hand. Memory in the human brain is a complex process which is easier understood by the use of theoretical constructs. Memories begin as sensory stimuli which become sensory memory which only last about one second, from there it moves into working memory which lasts for about twenty to thirty seconds and is used to process information. Within working memory there are a few separate processes, the central executive which directs attention, the episodic buffer which is a secondary storage lasting ten to twenty seconds, this area communicates with long term memory as well as the central executive. The visuospatial sketchpad which is used to visualise visual and spacial
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.
“Information flows from the outside world through our sight, hearing smelling, tasting and touch sensors. Memory is simply ways we store and recall things we 've sensed.” When we recall memories, the original neuron path that we used to sense the experience that we are recalling is refined, and the connection is made stronger. Sensory information in stored for only a few seconds in the cortex of the brain. This information can then progress to short-term memory, and then long-term memory, depending on the importance of the information received.
Two brain structures that could likely be affected by this damage are the frontal lobes and the temporal lobes. The frontal lobe produces speech, controls motor skills, and initiates leading functions such as thinking, personality, emotion and memory. (Huffman, K., Dowdell, K. 2015. Pg. 71). The temporal makes it possible for an individual to hear properly, comprehend language, recollect thoughts, and maintain emotional stability; this lobe also contains the auditory complex, which is responsible for the interpretation
There are 3 necessary steps/types that are crucial to forming a lasting memory. Step 1: sensory memory, step 2: short-term memory, and step 3: long-term memory. These are the three types of memory that are needed to build a lasting memory. Sensory memory is the shortest memory in the shortest- term memory element.One of the types of memory allows you to remember information through the 5 senses. The brain will remember anything that happened from 1 second to 60 seconds using the sensory part of your memory. An example of sensory memory is: I got hit in the head with a purple yo-yo. After sensory memory comes the short-term memory. Short-term memory acts as a “scratch- pad” for temporary recall. Short- term memory holds small amounts of information. Anything something that took place in front of your eyes for longer than 60 seconds, the short-term memory section of the brain will remember it. This section of your brain will allow you to recall that information in the next few hours or days. An example of short-term memory is: time on the clock 10 minutes ago. Lastly, comes long– term memory. Long- term memory, is used to store information of a set time
This supports the idea of an immediate memory store for items that are neither visual nor phonological and that draw on long-term memory to link the related words. It is used as both the Phonological Loop and the Visuo-Spatial Sketch Pad have specific roles and the Central Executive has very limited storage capacity so as a result there was no where to store both visual and acoustic information. The Episodic Buffer is an extra storage system that has in common with all working memory units, a limited capacity. It is handy and can integrate information from the Central Executive, The Phonological Loop, The Visuo-Spatial Sketch Pad and also information from the Long-Term Memory.
The part of the brain that is in charge of memory is called the hippocampus, which is part of the cerebral cortex. The cerebral cortex is in charge of thinking, problem solving, and many different kinds of language skills. People that have a problem with their hippocampus can have trouble remembering new details they have taken in. There are also many different parts of the hippocampus that apply directly to the memory. These parts include short-term memory, long-term memory, sensory memory, and the constructive processes. Short-term memory is the information that stays in your brain only when you are thinking about it, about 20 to 30 seconds. After this, it is most likely forgotten. Long-term memory is when your hippocampus keeps track of facts you learn, ideas you have, and experiences. Even when people stop thinking about these things, the memory can last a lifetime. Another part of the hippocampus, sensory memory, remembers information only for one or two seconds. The brain creates a mental image that disappears when you stop directly thinking about a particular thing. The last part of the hippocampus is the constructive processes. Constructive processes are memories that your brain makes up in order to make sense of a detail in which you only remember some of the details. The few details that the brain remembers are combined with other small details that your brain adds in order for it to
Research has shown that there is “greater activation in the left inferior frontal and medial temporal lobes” (Stanford, 2006, p. 208) during the encoding of words which were later remembered as compared to those which were forgotten. The sensations perceived by sensory nerves are decoded in the hippocampus of the brain into a single experience (Mastin, 2010). The hippocampus analyses new information and compares and asssociates it with previously stored memory (Mastin, 2010). Human memory is associative in that new information can be remembered better if it can be associated to previously acquired, firmly consolidated information (Mastin, 2010). The various pieces of information are then stored in different parts of the brain (Mastin, 2010). Though the exact method by which this information is later identified and recalled has yet to be discovered, it is understood that ultra-short term sensory memory is converted into short term memory which can then later be consolidated into long term memory (Mastin, 2010).
Examining the long-term effects of Traumatic Brain Injuries (TBI) are one of the many areas of brain behavior relationships neuropsychologists focus on. Consequently, studies review the effects obstacles have when attempting to remediate coping following TBI (Krpan, K. M., Anderson, N. D., & Stuss, D. T., 2013) while other studies have looked at the relationships between development in children who have suffered from TBI (Ganesalingam, K., Yeates, K. O., Sanson, A. and Anderson, V., 2007). In a highly specialized study, researchers discussed the sex differences in orbitofrontal connectivity in male and female veterans with TBI (McGlade, E., Rogowska, J. & Yurgelun-Todd, D., 2015). Nevertheless, while these studies are examining different ways TBI are influencing different behavioral changes in all ranges of people, they all focus on specific brain behavior relationships. The further purpose of these studies is to determine the best rehabilitation methods to achieve the highest possibility of cognitive functioning. Through the examination of how TBI effect certain areas of the brain, this will allow neuropsychologists to focus rehabilitation efforts specifically on the areas with the most concentrated brain damage.
The temporal lobes are one of the four main lobes located in the brain. They are located in the largest division of the brain best known as the forebrain or in scientific terms, as the Prosencephalon. There is one temporal lobe located in each hemisphere of the brain. Damage to the temporal lobes can present a number of issues. Damage resulting from a stroke or seizure can produce an inability to understand language or to speak properly. An individual may have difficulty hearing or perceiving sound. Temporal lobe damage may also result in the development of aggressive behavior, impaired memory formation, speech disorders, and
Some scientists believe that parts of long term memory are permanent while others will eventually weaken over time. (3) Long term memory can be divided into three sections: procedural memory, declarative memory, and remote memory. Procedural memory includes motor skills such as learning how to ride a bike or how to drive a car. "Such memories are slow to acquire but more resistant to change or loss." (4) Declarative memory is used to remember facts, such as names, dates and places. It is easy to learn but also easy to lose. Finally there is episodic memory, which is the record of events that a person stores throughout his or her experience. Recent studies show that these events, as soon as they occur, are sent to a temporary part of the brain called the hippocampus, and that over time they are moved to the neocortex for permanent storage. (5).
Steve Jobs once said, "You and I have memories longer he road that stretches out ahead". The brain is so detailed and holds so much information in every little area. There are so many things happening in the brain at once, and one of the most fascinating things would be memory. The memory has various abilities that make it so complex, including the memory system, how it functions, and memory retrieval, along with the capacity to memorize certain ideas easier
Damage to the frontal lobe cortex of the brain can cause difficulty in everyday activities. The frontal lobes role in people's behavior includes executive processes, language, emotional expression and movement. Ryan Godfrey has difficulties in some areas of executive processes due to the damage tumors caused in his brain. Ryan and others with frontal lobe damage can benefit from knowing these deficits by taking steps to reduce their impact. The brain tends to compensate for damaged parts and a faith in God brings power to overcome deficits. Thus, behavioral difficulties for frontal lobe damaged patients are only a guideline not a box, for nothing is impossible for God to accomplish.
Once again we look at how these areas function after being damage. For example damage to the premotor cortex may result in a range of problems such as apraxia, which is the inability to carry out actions that require skill that previously could be performed.
The frontal lobe is what controls the cognitive capabilities in a human. It controls the problem solving, sexual behavior, memory, social behavior, language, impulse control, and etc., amongst executive function. Executive function is mental skills that we use in an everyday task to get through things. If a frontal lobe is damaged it could cause memory loss, the change in mood, short temper, and the lack of control to manage behavior.
