SUMMARY The pigeon's use of different visuo-spatial cues was studied under controlled laboratory conditions that simulated analogous aspects of a homing situation. The birds first learned the route to a goal that was not visible from the starting location, but became visible as it was approached. Birds could orientate within a mainly geometric global reference frame, using prominent landmarks within their range, or by `piloting' along local cues. After learning the route, the birds were tested from familiar and unfamiliar release points, and several aspects of the available cues were varied systematically. The study explored the contribution of the left and right brain hemispheres by performing tests with the right or left eye occluded. The results show that pigeons can establish accurate bearings towards a non-visible goal by using a global reference frame only. Furthermore, there was a peak of searching activity at the location predicted by the global reference frame. Search at this location and directedness of the bearings were equally high with both right and left eye, suggesting that both brain hemispheres have the same competence level for these components of the task. A lateralization effect occurred when prominent landmarks were removed or translated. While the right brain hemisphere completely ignored such changes,the left brain hemisphere was distracted by removal of landmarks. After translation of landmarks, the left but not the right brain hemisphere allocated part of the searching activity to the site predicted by the new landmark position. The results show that a mainly geometric global visual reference frame is sufficient to determine exact bearings from familiar and unfamiliar release points. Overall, the results suggest a model of brain lateralization with a well-developed global spatial reference system in either hemisphere and an extra capacity for the processing of object features in the left brain.

The aim of our study was to test for lateralization of magnetic compass orientation in pigeons. Having shown that pigeons are capable of learning magnetic compass directions in an operant task, we wanted to know whether the brain hemispheres contribute differently and how the lateralization pattern relates to findings in other avian species. Birds that had learnt to locate food in an operant chamber by means of magnetic directions were tested for lateralization of magnetic compass orientation by temporarily covering one eye. Successful orientation occurred under all conditions of viewing. Thus, pigeons can perceive and process magnetic compass directions with the right eye and left brain hemisphere as well as the left eye and right brain hemisphere. However, while the right brain hemisphere tended to confuse the learned direction with its opposite (axial response), the left brain hemisphere specifically preferred the correct direction. Our findings demonstrate bilateral processing of magnetic information, but also suggest qualitative differences in how the left and the right brain deal with magnetic cues.

Selection Mechanisms

Individual fitness often depends on the ability to inhibit behaviours not adapted to a given situation. However, inhibitory control can vary greatly between individuals of the same species. We investigated a mechanism that might maintain this variability in zebrafish ( Danio rerio ). We demonstrate that inhibitory control correlates with cerebral lateralization, the tendency to process information with one brain hemisphere or the other. Individuals that preferentially observed a social stimulus with the right eye and thus processed social information with the left brain hemisphere, inhibited foraging behaviour more efficiently. Therefore, selective pressures that maintain lateralization variability in populations might provide indirect selection for variability in inhibitory control. Our study suggests that individual cognitive differences may result from complex multi-trait selection mechanisms.

Insight Into

We know little about the neurologic bases of art production. The idea that the right brain hemisphere is the “artistic brain” is widely held, despite the lack of evidence for this claim. Artists with brain damage can offer insight into these laterality questions. The authors used an instrument called the Assessment of Art Attributes to examine the work of two individuals with left-brain damage and one with right-hemisphere damage. In each case, their art became more abstract and distorted and less realistic. They also painted with looser strokes, less depth and more vibrant colors. No unique pattern was observed following right-brain damage. However, art produced after left-brain damage also became more symbolic. These results show that the neural basis of art production is distributed across both hemispheres in the human brain.

The Brain

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.

Neuropsychiatric Conditions

Brain asymmetry is a hallmark of the human brain. Recent studies report a certain degree of abnormal asymmetry of brain lateralization between left and right brain hemispheres can be associated with many neuropsychiatric conditions. In this regard, some questions need answers. First, the accelerated brain asymmetry is programmed during the pre-natal period that can be called “accelerated brain decline clock”. Second, can we find the right biomarkers to predict these changes? Moreover, can we establish the dynamics of these changes in order to identify the right time window for proper interventions that can reverse or limit the neurological decline? To find answers to these questions, we performed a systematic online search for the last 10 years in databases using keywords. Conclusion: we need to establish the right in vitro model that meets human conditions as much as possible. New biomarkers are necessary to establish the “good” or the “bad” borders of brain asymmetry at the epigenetic and functional level as early as possible.

This is the last phase of a four-year study which aimed to determine the significance of the difference in the mathematics (math) performance of the participants when grouped according to their hemispheric dominance (HD). The study was anchored in the Split-Brain or Lateralization Theory of Roger Wolcott Sperry which states that the brain is divided into two hemispheres, the left, and the right hemisphere. The participants were eighty-eight (88) fourth-year college students from the courses of Bachelor of Science in Mathematics (BSM), Bachelor of Science in Education major in Mathematics (BSEd), Bachelor of Science in Electrical Engineering (BSEE), Bachelor of Science in Electronics and Communication Engineering (BSECE), and Bachelor of Science in Mechanical Engineering major in Automotive Engineering (BSMEAE) at Western Visayas College of Science and Technology SY 2014-2015. The participants’ HD was determined by the use of a researcher-made 46-item Hemispheric Brain Dominance Test while their mathematics performance was based on their Math classes average final grades. The statistical tools used were the mean, standard deviation, Mann-Whitney, Kruskal-Wallis, and Post hoc tests. The hypothesis was set at the 0.05 alpha level. As an entire group, the left brain was the dominant brain hemisphere among the participants from phase I to phase IV. When the participants were grouped according to program in phase I, the BSM, BSEd, and BSMEAE was left-brain dominant while the BSEE participants were right-brain dominant. The BSECE had an equal number of left-brained and right-brained participants. In phase II, the dominant brain hemisphere was the left brain. Only the BSEE participants were right-brain dominant. In phase III, the dominant brain hemisphere was the left brain, except for the BSMEAE where there was an equal number of left-brained and right-brained participants. In phase IV, all participants from the different programs were left-brained. Only the BSEE participants were right-brain dominant. As an entire group, phase I and II participants had “fair” mathematics performance; phase III had “good” mathematics performance, and phase IV had “very good” mathematics performance. When the participants who were right-brained were grouped according to mathematics performance, phase I had “conditional” mathematics performance; phase II and III had “fair” mathematics performance; and phase IV had “good” mathematics performance. Those who were left-brain dominant had “fair” mathematics performance in phase I, “good” mathematics performance in phase II and III, and “very good” mathematics performance in phase IV. In all phases of the study, significant differences existed in the level of mathematics performance when the participants were grouped according to their hemispheric brain dominance. The “left-brained” performed better in mathematics than the “right-brained”. There was a significant decrease in the enrolment of participants who were right-brain dominant because they shifted to other courses or they transferred to other schools. In phases, I, II and III, significant differences existed in the level of mathematics performance when the participants were grouped according to their program. There is no significant difference in the hemispheric brain dominance of the participants when grouped according to the phase of the study. This implies that the slight changes in the hemispheric brain dominance of the participants were not significant in the last four years.

Communication is an intuitive as well as cognitive process. In order to develop the brain skill of intuition, it is sometimes necessary to shut down cognitive (left-brain analyses and pay special attention to intuitive (right-brain) ways of knowing. The brain hemispheres work differently and yet in conjunction. This article suggests techniques for developing intuitive brain skills. Mandalas, “other” hand writing, and positive affirmations can be used to improve intuitive skills.
