Memory in humans is a complex process and is divided into multiple components. Different areas of the brain are responsible for varying functions relating to memory such as short term memory and long term memory, which can further be broken down into subcategories such as emotional and semantic memory. Using fMRI, brain regions that participate in memory can be pinpointed and changes to memory that are resultant of aging or other neurological diseases and the pathology of the underlying brain structures can be detected as well. An example of a study done on memory was performed by Todd and Marois, with a goal of observing the role of the posterior parietal cortex in visual short term memory. To achieve this, seventeen subjects were given a visual delayed match to sample task during which the subjects were first shown a display of one to eight colored discs and after a timed delay had to indicate whether a probe disc matched one of the discs from the initial sample. In addition, to reduce any effects of the subjects using verbal strategies, the subjects had to simultaneously maintain a two digit number across the delay period. The results showed that the accuracy of responses decreased as the number of discs presented at the start of the trial increased. Moreover, it was established that the average visual short term memory capacity was capped at three to four objects. fMRI data was collected and analyzed from three brain regions: the intraparietal sulcus/inferior occipital sulcus (IPS/IOS), the ventral-occi pital cortex (VO) and the anterior cingulate cortex (AC). Activity in the IPS/IOS seemed to increase as the load of the task increased and it was shown that this region was active during maintenance and encoding. On the other h... ...Alzheimer’s, the roles cognitive reserve and compensatory recruitment can be observed. For example, education level and overall intelligence might alleviate some of the cognitive and memory deficits seen with age and disease related brain changes. Compensatory recruitment, such as bilateral activation of frontal regions on a verbal memory task compared to the left-lateralized activation seen with younger adults during the same task, is observed in older adults as well. These articles illustrate the point that there are multiple memory systems with differing functions. Taken together, these findings help explain why patients with brain damage to different regions do not always exhibit the same neurological deficits associated with memory. The use of fMRI has been extremely successful in identifying which brain regions are necessary for the multiple types of memory.

Generally, Laggard High School is a safe place for students.

The buildings and classrooms are well-structured and convenient for both teachers and students. I feel safe inside these classrooms since they are complete with the facilities and materials we need for teaching and learning. Moreover, I also feel safe in school because of the presence of the fire service. Probable fire incidents, as well as other untoward emergencies that may happen in the building, can be easily prevented because of an efficient and effective fire service just across the street. Being bounded by an ivy-league university like the Baylor University creates a positive influence on the part of the students as well as the community. Since high school students see what university students do, they pretty much have an idea of what life in the university is, which could lead them to pursue their own education, if not in Baylor, then in other colleges or universities in the city or in another state. It is a good thing that Baylor is there because as early as freshman in high school, a student can already be influenced to think about what course or study to pursue. Furthermore, since Baylor is a Christian school, particularly the largest Baptist university in the world in terms of enrollment, it fosters a caring and sensitive atmosphere not just for the students in Baylor but also for the whole of the community. Baylor University’s presence generates a sense of safety and security on my part, because I do not have to worry much about Laggard High School’s students’ future. However, not all areas in and around Laggard High School foster a friendly and safe ambiance. Since numerous cars enter through the main entrance and students need to stay behind the main door until 8:30 in the morning, possible accidents may happen. Students flock near the main entrance to wait for time as cars come and go. This could be a trouble area especially for students entering the school and those closest to the car park, who are consumed with their conversations that they do not notice the cars coming in and out of the school premises. This somehow unsafe and trouble area can be fixed by having someone monitor or guard the students coming in as well as the cars that enter and leave the school premises. Also, a conducive and comfortable waiting area, where students who come in early can stay, should also be designated. Another possible solution is letting the students enter 10 minutes before the time so that they can settle and be safe inside their classrooms. In addition, some cars entering the main entrance can use the entrance near Central Avenue so that the number of cars entering along with the students via the main entrance will be lessened, thus less accidents are avoided. Another area I do not feel safe in is the cafeteria. This could be another possible trouble spot because the area lacks adequate monitoring. There should be someone designated to monitor the hall. Monitoring would include watching over the behavior of the students to avoid any untoward trouble among them, as well as restricting the students to go from the cafeteria to the playground. Some students use the cafeteria to sneak out and play in the playground. And since the school lacks sufficient monitoring on some areas and on students’ behavior, we do not know if they could be safe in their playing. Moreover, since they have easy access to the playground, they are influenced to stay there longer than they are supposed to. We do not want this because our real focus is their learning inside the classroom. Students should be advised to know their time for study and their time for play. The Laggard High School is generally a very conducive and safe place for students, but then it also faces monitoring problems that need to be studied so that students, teachers, and parents would feel much safer.

Single-Sex Schooling Causes Stereotyping and Legitimizes...

There is a long history of single-sex schooling, in which males and females attend specific classes or schools only with members of their same sex. This separation of genders may be done for educational purposes or in combination with other factors, such as social interactions that occur between male and female students. There is some support for the idea that single-sex schooling can be beneficial, especially for outcomes related to academic achievement and more positive academic aspirations (Lee, 2008). Although, there are many benefits of children attending single-sex schools, evidence shows that sex segregation can also gender stereotyping and legitimizes institutional sexism (Kennedy, 2000). One of the benefits of attending single sex†¦show more content†¦The study was the first meta-analysis of sex differences in brain structures - which resulted in evidence that female brains are different than mal. The results of the Cambridge University study showed that male brains have an average of a total capacity that is between eight and thirteen percent larger than females. Because of this data, there is a great chance that coeducation will not work satisfactorily for every student, especially in relation to teaching methods that cater better to one specific gender than the other. Thus, males and females are proven to learn differently, and contain information differently as well. The theory that males and females think and learn differently has come from a range of sources and ideas, including research on the brain. According to a 2007 longitudinal pediatric neuroimaging study led by a team of neuroscientists from the National Institute of Mental Health, various brain regions develop in a different sequence and tempo in girls compared with boys (NeuroImage, Vol. 36, No. 4). Using 829 brain scans gathered over two years from 387 subjects from 3 to 27 years old, researchers found several remarkable differences. The occipital lobe, for example — the one most associated with visual processing — shows rapid development in girls 6 to 10 years old, while boys show the largest growth in this region after 14 years old. Other studies have also shown disparities in language processing between the
