Download file to see previous pages The acquisition of literacy of education rests on the development of elaborate links that exist between vision and language (Hugdahl & Westerhausen, 2010). The visual system of the human brain learns how to recognize rapidly letters and letter clusters that are across a huge range of shapes and viewing conditions. Hugdahl and Westerhausen (2010) argue that the efficiency of the adult reading system rests on the brain’s ability to identify rapidly and in parallel arrays of numerous letters. Undeniably, word reading latencies are reasonably constant regardless of the word length, at least with a reasonable range of three to six letters. According to Bryden (2012), this perceptual ability takes approximately five years of instruction to develop, and an effect of word length sticks at the least to an age of 10 years.
Language is possibly the most distinguished and powerfully lateralized function in the human brain. Much of knowledge on the organization of language in the human brain is grounded on the correlation of location of lesions in the neo-cortex and behavioral deficits (Bryden, 2012). Notably, several language areas in the brain are located within the left hemisphere. A puzzling attribute of the structure of the human brain is that its two hemispheres are functionally and anatomically asymmetrical. The asymmetries in the structure of the brain are not only visible in a general view but also at the degree of the morphology of a person’s neuron (Corballis, 2012). Conversely, even though there is a little discrepancy between facts of asymmetry in the brain, there is substantial disagreement about why the two hemispheres are asymmetrical.
Anatomical asymmetries in the human brain mainly center on the language areas (Corballis, 2012). However, it is tempting to speculate that anatomical asymmetries evolved to subserve language. Besides, these asymmetries ...Download file to see next pagesRead More

Reaction Time & Hemispheric Asymmetry

.... With optimal interconnectedness between hemispheres, the innate tendencies of either sex to drift towards the coldly analytical or the purely intuitive can be moderated for results that confound stereotypes. (Kimura, 2000) There is some ambiguity to what extent sex-specific asymmetries are found in humans. Human male fetuses have been found to possess a larger right hemisphere volume in utero, but it is difficult to identify any conclusive corroboration in adults. (Kimura, 2000) Studies of Cerebral lateralization have suggested that elevated testosterone levels might be causative of deviations from the typical dominance patterns; being, right-handed with leftward language dominance, as...

For this study, pre-cultured HeLa cells were counted and then plated on coverslips placed in culture dishes. The cells, attached to the coverslips, were washed with phosphate buffered saline (PBS) and fixed using chilled methanol or paraformaldehyde (PFA), depending upon the protein to be stained. The PFA fixed cells were...

Cerebral Lateralization: Cerebral Asymmetry Practical

...Cerebral lateralization: Cerebral Asymmetry Practical. This experiment was set to investigate cerebral asymmetry among thirty participants. The aim of this experiment was to find out the accuracy speed of phonological processing in the left and right hemispheres. The hypothesis for this study was “verbal processing as measured by the rhyme/non-rhyme task is faster and more accurate in the left hemisphere than the right hemisphere of the brain”. Several pairs of words with a destructor were given to the participants. They were then asked to show out which words either rhymed or did not rhyme. The participants of the study...

...behavioral and mental improvements in their patients (Paul n. p.). Specific support processes for my sister’s health and safety include regular physical therapies with a specialized therapist, counseling for better emotional health, hearing aids to reduce hearings and listening problems, eye lenses for clear vision and medicines to deal with other issues. The total lifetime cost of cerebral palsy patient’s treatment is $921,000 according to the Morbidity and Mortality Weekly Report (“Cost of Cerebral Palsy” n. p.). However, the emotional cost of experiencing life with a CP patient and that too your own sister is far more than the amount that could be hold by mathematical digits. Looking...

.... A polymorphism of this gene is reported to be associated with increased risk of osteoporotic fractures and gastric cancer (Coleman 2006, 39). 2.3 PCR Amplification DNA sample obtained from the cheek cells should be amplified so as to improve the probability of obtaining viable results from them. One of the methods used to amplify the DNA fragments is the Polymerase Chain Reaction (PCR). The technique is so far one of the fastest means of amplifying DNA samples. It is also specific and dependable. The method, however, require that the sample be cloned and previously sequenced using other available traditional methods. It call for two oligonucleotide primers, template DNA, buffer, thermostable enzyme Taq polymerase and...

...Experiment: Spectrophotometric investigation of a first order reaction Theory First Order Reaction A first order chemical reaction is one in which rate of reaction is directly proportional to concentration of a reactant. This can be schematically represented as A Products And rate of reaction is given as d[A] ⎯⎯⎯⎯⎯⎯⎯ = - λ[A] dt Where [A] is instantaneous concentration of A i.e. concentration of A tat time t and λ is the rate constant of the reaction. d[A] Therefore, ∫⎯⎯⎯⎯⎯ = - λ∫dt [A] Now integrating this between limits [A] = [Ao] at t = 0 and [A] at any point of time t the rate equation becomes ln[A] – ln[Ao] = - λt ; where ln is natural log of [A] This can...

Cerebral Palsy

...Cerebral Palsy According to the Centers for Disease Control and Prevention (CDC) , the average prevalence of cerebral palsy is 3.3 per 000 8-year old children or 1 in 303 children, in three specific states, which is slightly decreased as compared to the 3.6 per 1,000 or 1 in 278 children the previous year. Although statistics may show a positive drop, continuous efforts for awareness and prevention are conducted to lessen the number of children that would suffer the chronic, lifelong, incurable condition. The Disorder Cerebral Palsy is defined by CDC (2010) as “a group of disorders that affect a person’s ability to move and keep their balance and posture as a result of an injury to parts of the brain, or as a result of a problem... with...
