Recovery of cognitive functions after brain damage is a crucial concern, but is also a difficult topic to explore through research experiments, mainly due to ethical concerns. As such, numerous research on the effects of environmental stimuli on brain plasticity had been carried out on animal subjects, which have indicated that an enriched auditory environment not only enhances auditory functioning, but also enhances general learning and memory systems (Särkämö et al., 2010). Särkämö et al. (2010) aimed to examine the effects of auditory stimuli on human brain recovery by measuring the activity of MMN, a brain region that responds to changes in auditory stimuli even without conscious awareness, and thus is a well-known index of studying auditory …show more content…
(2010) recruited 60 MCA stroke patients (of which, 54 completed the study) from the Department of Neurology of the Helsinki University Central Hospital. Those recruited were all ≤75 years of age, Finnish-speaking, right-handed, with no hearing deficit, and no previous psychiatric or neurological disease. A researcher uninvolved in enrollment of patients randomly assigned all the subjects into one of three groups: a music group, an audiobook group, or the control group. The two experimental groups were instructed to listen to their assigned material for a minimum of one hour per day for the next two months (their participation was verified via listening diaries), while the control group was not presented with any listening material. Questionnaires were completed by all participants during the first week and at the end of six months to examine patients’ leisure activities and to verify their participation in the experiment. One week (baseline), three months, and six months after the stroke, MMN and neuropsychological testing were executed. MMN responses to changes in frequency and duration of audio tones were measured using magnetoencephalography (MEG) and neuropsychological tests consisted of story recall and word list learning tasks for assessing verbal memory, and Stroop subtests (from CogniSpeed© software) and mental subtractions for assessing focused attention (Särkämö et al., …show more content…
These increases in MMN responses in both the experimental groups also correlated with improved performance on story recall and mental subtraction tests as compared to the control group. Särkämö et al. (2010) suspected that the reason performance on story recall and mental subtractions were improved while Stroop subtests and word list learning tasks weren’t, was because the former tests revolved around utilization of working memory and speech comprehension, of which both are associated with auditory sensory

Post Traumatic Brain Injury Case Study

Problem Statement Mild Traumatic Brain Injuries (mTBI) in the form of concussions are very dangerous injuries that can have lengthy recovery times as well as lasting impacts on patients increasing their risk for other neurodegenerative diseases, like PTSD and depression. Kimbler writes that “…overall, TBI is more prevalent than breast cancer, AIDS, multiple sclerosis, and spinal cord injury combined” (2011) showing the relevance of neuro damage. Concussions are relevant in three main categories…

devastating. Football players sometimes refer to getting a concussion as getting their “bell rung” because of the ringing noise they hear in their head. A concussion is a traumatic injury to the brain that can occur with or without a period of unconsciousness. It is caused by a hard hit to the head when the brain is jolted against the skull. The effects of a concussion can include, but are not limited to, headaches and problems with concentration, memory, balance and coordination. These problems can…

The human brain is one of the most interesting and intriguing organs in the human body, and if not properly cared for, there can be consequences that can be felt throughout the whole body. As social workers, we need to be aware of how the human brain, along with the central nervous system (CNS), which the brain is a part of, can be affected when the client is in distress or using substances.

The French neuroanatomist Paul Broca first discovered Broca’s area in 1861 when he dissected the brain of his patient, ‘tan’, with an area of damage in the left frontal cortex, which resultantly became known as Broca’s area (Dronkers, Plaisant, Iba-Zizen & Cabanis, 2007). Due to Broca’s area being situated in the left hemisphere of the brain the main effect suffered is language problems, however there are often commonly associated weaknesses with the limb movement of…

A stroke also known as a “brain attack, is an event in where the blood supply to your brain is cut off. When this occurs the brain cells needed in order to function regularly; become deprived of oxygen and subside. In contrary to what many may believe, there is no specific age range in being subjected to a stroke, and affect more than 800,000 individuals each year. Although this event is the fifth leading cause of death in the United States, 80 percent of strokes can be prevented. In the event that…

athletes and non-athletes. This in turn has started discussions on prevention, management, and long-term consequences. Concussions are a type of traumatic brain injury that is caused by a hit to the head or a hit to the body that causes the head to move suddenly. The sudden movement causes the brain to suddenly shake in the skull, sometimes damaging brain cells. Signs of a concussion usually show up soon after the injury is caused. There are seven observable signs and seven reported symptoms. Some of…
