This paper presents the design of Mini Brain Games (MBGs) to improve either the left or right hemisphere of the brain. The MBG includes spot the difference, piano, block view, word building, word scrambler, sudoku, left hand control, memory card, flash card, crossword, math logic and mnemonics technique used for the order of operations in algebra, the planets in solar system, and resistor color code. Stroop test and brain dominance test are used to measure the level of balance between the two hemispheres of the brain before and after the exercise program. The mini brain games designed in the Brain Balancing System Windows Application are shown to improve the balance between the left and right hemisphere of the brain. The results show that the mini brain games are indeed able to assist in the left or right brain development. The largest improvement achieved is that the percentage of dominance between the two brain hemispheres is reduced by 18.18%. The smallest improvement achieved was that the difference between the two brain hemispheres was reduced by 9.08%.

The aim of this research is to evaluate the change in the hand grip strength of the male arm wrestlers before and after a unit of exercise. The participants of the research consist of sportsmen (n=16) of Fırat University arm wrestling team in 18-25 age group.Within the scope of the research, all of the tests and measurements (age, length, body weight, sports age, hand grip strength) were carried out on the experimental group before they started training and the same tests were repeated just after the exercises. A unit of exercise program consisted of warm up, cool down, and 5 sets of weight lifting with 12 repetitions and intensity of 70% that were in that day’s plan and program applied by the trainer.While descriptive statistics were adopted in the statistical analysis, to identify the significance level between the hand grip strength before and after the exercise paired sample t-test analysis was used. The significance level was shown as α = 0.05 in the analyses. While the right hand grip strength of the sportsmen (n=16) was statistically significant at 51.1062 ± 1.69709 before and 49.0437 ± 1.71770 (p=0.000) after the exercise, the left hand grip strength was statistically significant at 46.9000 ± 1.16179 before and 45.8063 ± 1.30078 (p=0.000) after the exercise.In conclusion, it was observed that there is a statistically significant negative decline in the hand grip strength of the arm wrestling sportsmen after a unit of exercise and it can be said that it is because of the exhaustion expected after the exercise.

ABSTRACT:Background:Constructional impairment following left vs. right hemisphere damage has been extensively studied using drawing tasks. A confounding factor in these studies is that right-handed patients with left hemisphere damage (LHD) are often forced by weakness to use their non-dominant (left) hand or hemiparetic dominant hand. Qualitative differences in the drawing characteristics of left and right hand drawings by normal subjects have not previously been characterized. The present study was undertaken to determine the qualitative differences between left and right hand drawings of normal subjects.Methods:Thirty right-handed, elderly subjects without a history of neurological disease were asked to draw, from memory, seven objects using the right and left hand. Half of the subjects were randomly assigned to draw with the left hand first, and half the right hand first. Right and left hand drawings were compared using a standardized scoring system utilized in several previous studies of drawing in focal and diffuse neurological disease. Each drawing was scored on eighteen criteria. Right and left hand drawing scores were then compared using the t-test for paired samples or the Wilcoxon matched-pairs testResults:Drawings made using the left hand were found to be significantly simpler, more tremulous and of poorer overall quality than drawings made by the same subjects using the right hand.Conclusions:The deficits found in left versus right hand drawings of normals are similar to those found in patients with LHD, suggesting that much of the drawing impairment seen following LHD is due to an elementary motor disturbance related to use of the non-dominant hand.

The aim of this research is to produce a training model for attacking football and also to refute its effectiveness for children aged 16 years. As for the steps in developing the research, the Borg and Gall steps involved 15 subjects for the small test and 60 for the large test. Qualitative data were obtained from observations, documentation and interviews; meanwhile, for the quantitative data using the effectiveness test. The trial of this study used pre and post tests with 10 opposing criteria. In mathematical calculations the significance of the difference t-count = -28.971, db = 43 and p-value = 0.00 <0.05, which means it contains significance before and after giving treatment. It can be concluded that the model is applied effectively to improve the ability for attacking amongst school students aged 16 years. Thus, representing the differences in motor skills highlights the principle of specificity for attacking training at the age of 16 must be considered that the load of portions in the exercise program can be maximized.

This is a neuro-linguistic research which compares Bangla speaking right hemisphere damaged (furthermore to be called RHD) male participants to age and gender matched normal males who have been selected from the same family as the right hemisphere damaged participants. RHD or right hemisphere damaged participants are those who have lesions or damages in the right hemisphere of the brain or both. This paper pertains to the understanding how a lesion or a damage in the right hemisphere can cause changes in the pattern of communication of adult males in the age group of 45 to 70. This paper discerns the difference in durations of controlled speech in RHD males compared to age and gender matched normal controls. It will be measured with the help a predetermined passage. A passage will be played to them, using a media player (to make sure everyone listens to the same recording, ruling out chances of error there) and then they will be asked to repeat the same passage, as much as they can remember. In this research, we will be looking at the time they would take to narrate the whole passage without missing out on anything.

According to some authors, changes in the electroencephalogram (EEG) in the absence of clinical paroxysmal manifestations should be considered as subclinical epileptic manifestations. Verification of this hypothesis on the basis of the auto-spectral Fourier analysis of the EEG was the purpose of this work. Were examined in 27 women, mean age of 35.4±2.48 years, right-handed, without paroxysmal clinical and EEG manifestations (first group) and 25 women, mean age of 36.2±2.17 years, right-handed, without paroxysmal clinical manifestations, but with epileptiform activity on EEG (second group). In the second group were registered the increase in faverage of the brain EEG (p<0.001), while was increased faverage both of the left and right hemisphere (p<0.01). Zonal peculiarities of bioelectric activity of a brain of the second group surveyed was a significant increase in faverage EEG in all investigated leads (p<0.01), resulting in total liquidation of zonal differences (p>0.05). The results of the analysis allowed to conclude that the registration of the EEG epileptiform paroxysmal phenomena without clinical manifestations should be considered as a subclinical stage of epilepsy.

Positive Effect

Speech is an attribute of the human species. Central speech disorders following stroke are unique models for the investigation of the organization of speech. Achievements in neurobiology suggest that there are possible neuroendocrine mechanisms involved in the organization of speech. It is known that the neuropeptide vasotocin, analogous of vasopressin in mammals, modulates various components of vocalization in animals. Furthermore, the positive influence of vasopressin on memory, which plays an important role in the formation of speech, has been described. In this study, speech organization processes and their recovery with the administration of vasopressin (1-desamino-8-D-arginin-vasopressin) to 26 patients with chronic aphasias after stroke were investigated. Results showed that sub-endocrine doses of the neuropeptide with intranasal administration had positive influence primarily on simple forms of speech and secondarily on composite forms. There were no statistically significant differences between the sensory and integrative components of the organization of speech processes with vasopressin. In all cases, the positive effect of the neuropeptide was demonstrated. As a result of the effects, speech regulated by both brain hemispheres improved. It is suggested that the neuropeptide optimizes the activity both in the left and right hemispheres, with primary influence on the right hemisphere. The persistence of the acquired effects is explained by an induction of compensatory processes resulting in the reorganization of the intra-central connections by vasopressin.

AbstractWe have identified the brain areas involved in Manual Preference (MP) in 143 left-handers (LH) and 144 right-handers (RH)). First, we selected the pairs of homotopic regions of interest (hROIs) of the AICHA atlas with significant contralateral activation and asymmetry during the right-hand and the left-hand Finger-Tapping (FT) both in RH and LH. Thirteen hROIs were selected, including the primary and secondary sensorimotor, and premotor cortices, thalamus, dorsal putamen and cerebellar lobule IV. Both contralateral activations and ipsilateral deactivations (reversed for the cerebellum) were seen in primary motor and somatosensory areas, with stronger asymmetries when the preferred hand was used. Comparing the prediction of MP with different combinations of BOLD variations in these 13 hROIs, the differences between movement of the preferred hand versus that of the non-preferred hand within the contralateral and/or ipsilateral cortices of 11 hROIS performed best at explaining handedness distribution, Handedness is thus supported by: 1-between-hand variations of ipsilateral deactivations of hand primary sensorimotor and secondary somatosensory cortices and 2-variations in regions showing the same profile in left and right-handers during the right or left FT. The present study demonstrates that right and left-handedness are not based on mirrored organization of hand control areas.

Recently obtained data from interdisciplinary research has expanded our knowledge on the relationship between language and the brain considerably. Numerous aspects of language have been the subject of research. Visual word recognition is a temporal process which starts with recognizing the physical features of words and matching them with potential candidates in the mental lexicon. Word frequency plays a significant role in this process. Other factors are the similarities in spelling and pronunciation, and whether words have meanings or are simply letter strings. The emotional load of the words is another factor that deserves a closer inspection as an overwhelming amount of evidence supports the privileged status of emotions both in verbal and nonverbal tasks. It is well-established that lexical processing is handled by the involvement of the brain hemispheres to varying degrees, and that the left hemisphere has greater involvement in verbal tasks as compared to the right hemisphere. Also, the emotional load of the verbal stimuli affects the specialized roles of the brain hemispheres in lexical processing. Despite the abundance of research on processing of words that belong to languages from a variety of language families, the number of studies that investigated Turkish, a language of Uralic-Altaic origin, is scarce. This study aims to fill the gap in the literature by reporting evidence on how Turkish words with and without emotional load are processed and represented in the brain. We employed a visual hemifield paradigm and a lexical decision task. The participants were instructed to decide if the letter strings presented either from the right or the left of the computer screen were real words or non-words. Their response times and accuracy of their answers were recorded. We obtained shorter response times and higher accuracy rates for real words than non-words as reported in the majority of studies in the literature. We also found that the emotional load modulated the recognition of words, supporting the results in the literature. Finally, our results are in line with the view of left hemispheric superiority in lexical processing in monolingual speakers.

The present study investigated the relationship between Iranian English language teachers’ reflectivity and their brain dominant quadrants. To this end, 102 Iranian EFL teachers at several language institutes and universities (i.e., Bojnord, Ghochan, Gonabad, Kashmar, Shandiz, Neyshaboor, & Mashhad) in Iran participated in this study. The Brain Dominance Survey which was developed by Ashraf, Tabatabaee Yazdi, & Kafi was employed to categorize participants as right and left brain dominant, and English Language Teaching Reflection Inventory developed by Akbari, Behzadpoor, & Dadvand was administered to measure teacher reflectivity. Then the data was analyzed using hierarchical multiple regression analysis to investigate the extent to which teachers’ brain dominant quadrants might have predictive power in their reflective teaching practices. Results indicated a statistically positive significant correlation with teachers who used their A quadrant and teaching reflectiveness whilst teachers with C quadrant dominance had a negative significant correlation with being reflective. Moreover, regression analyses revealed that there is no significant relationship between reflectivity and teachers’ B and D brain quadrants dominance. To teach more reflectively, teachers need to better understand their brain differences and how it can affect the teaching strategies. All teachers should find ways to combine teaching activities that involve both left and right of their brain, and not only practice six underlying factors of reflection in their teaching but also employ reflective procedures in order to develop their reflective practices.

20 normal, right-handed, familial dextral men performed (a) unimanual finger tapping, (b) encoding of schematic faces at three levels of difficulty (3, 5, and 7 faces), (c) verbal production, (d) concurrent tapping and verbal production, and (e) concurrent tapping and face encoding. Subsequent recognition of faces was disrupted more by concurrent left-hand tapping than by concurrent right-hand tapping, supporting both the hypothesis that the right hemisphere mediates face encoding in adults and Kinsbourne and Hicks' (1978) “functional cerebral distance principle.” Left- and right-hand tapping rate and variability were not asymmetrically affected by either verbal production or face encoding. While there was an increase in generalized interference effects on face encoding, the degree of asymmetry of the interference remained constant. In addition, as the difficulty of the memory task increased, variability of tapping rate decreased. This was discussed in terms of attention and automatic motor programming.
