Behavior is lateralized when it is performed preferentially by one side of the body, and this phenomenon is seen across a wide range of vertebrate taxa. Furthermore the brain and body are contralateral in many animals, meaning that the left brain hemisphere most dominantly controls the right side of the body and vice versa. Lateralized behavior in humans and nonhuman primates reveals a population right-hand bias. Recent studies in primates have also begun to link differences in lateralized behavior to task complexity, and responses to novel versus familiar stimuli. Parallel research on cetaceans is sparse although evidence accrued over the last decade suggests captive dolphins have a preference for swimming counter-clockwise, a right-eye advantage in spatio-cognitive tasks and a right-eye preference for viewing novel objects, although this is the reverse of the general vertebrate pattern. Lateralized behavior was examined in a group of six male bottlenose dolphins (Tursiops truncatus) in response to a novel underwater maze, and compared to behavior during a baseline condition (no maze present). Dolphins were significantly more likely to swim counter-clockwise round their pool during both the baseline and maze condition, interpreted as a right eye bias. Swimming rotation was also weaker in dolphins during the maze condition, suggesting that the maze may have disrupted routine circular swimming behavior. There was no clear preference for using the left or right side of the maze, except in two high- using subjects with a strong right preference. Modifications and extensions to the methods are discussed.

A wide range of experimental pressure distributions along axisymmetric bodies was compared with the results of Landweber's potential flow calculation method. Apart from certain viscous effects, some discrepancies were found, and it is shown that blockage corrections are of the right order to account for these discrepancies. The calculation method was also used to show that the pressure distribution over the nose of the body is largely independent of the tail shape, and vice versa.

Abstract Here I try to improve on the available answers to certain long-debated questions and set out some consequences for the answers. Are there limits to the extent to which we can understand the conceptual worlds of other human communities and of non-human creatures? How does this question relate to our ability to engage in other cultures’ practices and languages? What is meant by ‘the body’ and what is meant by ‘the brain’ and how do different meanings bear on the questions? The central answer developed here is that it is possible, given the right circumstances, for a competent human from any human group to understand the culture of any other human group without engaging in their practices though there are barriers when it comes to communication across species. This answer has important social and political consequences and consequences for the debate about artificial intelligence.

A 37-year-old woman, Para 5+0 presented with a 1 year history of recurrent convulsions and progressive weakness of the right side of the body. She had been treated for postpartum eclampsia in her last delivery but symptoms recurred 3 months later. Evaluation including computerized tomography scan of the brain suggested a parieto-temporal meningioma, which was completely excised at craniotomy. Histology confirmed this to be a meningioma. The patient was well at 8 months of follow up. The growth of meningiomas may increase during pregnancy due to presence of receptors for progestational hormones in the tumour and the meningioma may become symptomatic in pregnancy, presenting as eclampsia. Close follow up of patients with eclampsia is necessary to identify neurological features that may lead to a diagnosis of meningioma. Early diagnosis is essential if a good outcome is to be ensured.

God created humans as the most special creation compared to His other creations. Human intelligence is caused by one organ which, although small in size, has a very vital role, namely the brain. Advances in knowledge and technology have encouraged scientists to try solving the mysteries of the brain. Many studies have focused on the right brain and left brain, or to balance the right brain and left brain. But in recent years, there has been a training/self-development institute who stated that they had found a way to balance the right and left brain, namely by activating the midbrain. This midbrain activation method is aimed at children aged 5-15 years because it is considered that children at this age are more easily activated in a very short time through a computer.The method used in writing this work is a Literature Study that contains various information on matters related to the topic of discussion. In addition to using literature, writing will be complemented by field research, using a Check List to interview respondents. The research approach used are qualitative and quantitative approach. A The qualitative approach obtains data regarding respondent's experiences. This writing has the aim of finding ( knowing ) whether the Midbrain Activation system is in accordance with God's Word or against God's Word; to open the horizons of parents, congregations and even readers of this paper, especially those with children, so that they can be more careful in choosing training for their children.

Eye Preference

Lateralization of behaviors and information processing are common across species. Hypothesized to be crucial for more efficient responding to environmental stimuli, lateralization has been investigated for a number of topics. Cetaceans are proposed to be hemispheric specialists, given a small corpus callosum, complete decussation of the optic nerve, and the ability to respond to a different visual stimulus presented to each eye simultaneously. Research with cetaceans has shown strong biases in a number of behaviors, including swimming, foraging, social interactions, and responses to myriad visual stimuli. Given similar evolutionary pressures, different species of cetaceans should display similar lateralized preferences. Previous research with bottlenose dolphins in managed care and wild striped dolphins indicated a right eye preference when viewing unfamiliar objects. The purpose of the current study was to evaluate the eye preference of belugas, bottlenose dolphins, and Pacific white-sided dolphins (lags) in managed care when viewing familiar and unfamiliar objects. The results from 11 belugas, 5 bottlenose dolphins, and 5 lags indicated that consistent group level eye preferences were not present. The belugas preferred to view both types of objects with both eyes, with the majority of the belugas showing a left-eye preference when a monocular gaze was used. Bottlenose dolphins tended to view both objects with their right eye while lags used their left eye when viewing objects. These results may have been affected by viewing objects below water versus above water. The belugas and the Pacific white-sided dolphins were able to view the objects below water, which may have elicited more naturalistic visual examinations of the objects (i.e., greater ecological validity). Viewing objects within one’s habitat may facilitate the discrimination of an object rather than simply its detection, which is may be more likely when encountering stimuli above the surface of the water as the bottlenose dolphins had to do in the present and past research. Future research should compare if presentation of the stimulus above water versus below water affects the eye preference displayed.

The study sample consisted male and female students at the academic year 2020/2021, and this sample was taken in a simple random way. Two measures were applied: Meta Cognition thinking, and brain dominance patterns, after confirming their psychometric properties. The results showed that the level of Meta Cognition thinking among Jordanian university students is (high), and that the dominant brain pattern among the study sample is the right pattern, followed by the left and then the integrated, and also there is no statistically significant relationship between the brain dominance patterns and the variables of gender and college, and there is statistically significant differences in Meta Cognition thinking among students with the (left) brain dominance pattern compared to those with the (integrated) brain control pattern and in favor of those with the left brain dominance type.

Music gives people a deeper understanding on the level of sensation and motivates them to become better and this element can change the world when it is wider than our own. It is music that connects the beginning to the end and becomes the literature of our heart. Fills the soul with affection, takes the mind from deep darkness to eternal heights. Music has the status of a® God, so purity has special importance in this genre. Music is the way to cultivate the mind through the seven pure and five vocal cords. Therefore, it can be said that music is necessary to keep the body and mind healthy, cheerful. This keeps the body, mind and brain healthy, and concentrates. Stress is also removed from music. It has been proved by various scientific experiments that both music practice and yoga practice develop strength in human life and many diseases can be treated. Music therapy i.e. music therapy nowadays plays an important role in relieving many health problems. Is playing If you live under high stress or are suffering from insomnia problem, then you can take help of this therapy. Each sound produces specific waves. These sound waves directly affect our brain. Everything in existence is affected by these waves. If a music is composed with the right words and the appropriate ragas, it will work on our brain in the same way that the software works inside a computer. Since our entire body is under the control of the brain, we can get the right result by having the expected effect on the brain through remedial music. संगीत लोगों को संवेदना के स्तर पर एक गहरी समझ देकर उन्हें बेहतर बनने की दिशा में प्रेरित करता है और यही तत्व जब निज से व्यापक होता है तो दुनिया भी बदल सकती है. ये संगीत ही है जो आदि को अंत से जोडकर हमारे हृदय का साहित्य बन जाता है। आत्मा को स्नेह से भर देता है मन को गहन अन्धकार से लेकर अनन्त ऊंचाइयों तक ले जाता है । संगीत क® ईश्वर का दर्जा प्राप्त है, इसीलिए इस विधा में शुध्दता का विशेष महत्व है। सात षुघ्द अ©र पांच क®मल स्वर®ं के माध्यम से मन क® साधने का उपाय है संगीत। अतः कहा जा सकता है कि शरीर तथा मन क® स्वस्थ््ा, प्रफुल्लित रखने के लिए संगीत आवश््यक है। इससे शरीर, मन, मस्तिष्क स्वस्थ््ा रहता है, एकाग्र रहता है। संगीत से तनाव भी दूर ह®ता है। विभिन्न वैज्ञानिक प्रयोगों द्वारा यह सिद्ध हो चुका है कि संगीत साधना व योग साधना दोनों से मनुष्य के जीवन में शक्ति का विकास होता है और अनेक बीमारियों का उपचार किया जा सकता है म्यूजिक थेरेपी यानी संगीत चिकित्सा आजकल अनेक स्वास्थ्य समस्याओं से राहत दिलाने में अहम भूमिका निभा रही है। आप अगर ज्यादा तनाव में रहते हैं या अनिद्रा की समस्या से पीडित हैं तो इस चिकित्सा की सहायता ले सकते हैं । हर ध्वनि से विशिष्ट तरंगें पैदा होती हैं। ये ध्वनि तरंगें सीधे हमारे मस्तिष्क को प्रभावित करती हैं। इन्हीं तरंगों से अस्तित्व में मौजूद हर चीज प्रभावित होती है। अगर कोई संगीत सही शब्दों और उपयुक्त रागों के साथ तैयार किया जाए तो वह हमारे मस्तिष्क पर उसी तरह काम करेगा जैसे किसी ’कम्प्यूटर’ के अंदर ’साफ्टवेयर’ काम करता है। चूंकि हमारा पूरा शरीर मस्तिष्क के नियंत्रण में होता है, इसलिए हम मस्तिष्क पर उपचारी संगीत के माध्यम से अपेक्षित प्रभाव डालकर सही परिणाम प्राप्त कर सकते हैं।

Humans observe a wide range of actions in their surroundings. How is the visual cortex organized to process this diverse input? Using functional neuroimaging, we measured brain responses while participants viewed short videos of everyday actions, then probed the structure in these responses using voxel-wise encoding modeling. Responses were well fit by feature spaces that capture the body parts involved in an action and the action’s targets (i.e. whether the action was directed at an object, another person, the actor, and space). Clustering analyses revealed five large-scale networks that summarized the voxel tuning: one related to social aspects of an action, and four related to the scale of the interaction envelope, ranging from fine-scale manipulations directed at objects, to large-scale whole-body movements directed at distant locations. We propose that these networks reveal the major representational joints in how actions are processed by visual regions of the brain.Significance StatementHow does the brain perceive other people’s actions? Prior work has established that much of the visual cortex is active when observing others’ actions. However, this activity reflects a wide range of processes, from identifying a movement’s direction to recognizing its social content. We investigated how these diverse processes are organized within the visual cortex. We found that five networks respond during action observation: one that is involved in processing actions’ social content, and four that are involved in processing agent-object interactions and the scale of the effect that these actions have on the world (its “interaction envelope”). Based on these findings, we propose that sociality and interaction envelope size are two of the major features that organize action perception in the visual cortex.
