The present study identified the brain based learning activities on the individual learning senses by using the brain laterality and the whole brain index. Students receive the information through the visual, auditory, and kinesthetic senses by Politano and Paquin's (2000) classification. These learning senses are reflected on brain by the various combinations of senses for learning. Measuring the types of the learning senses involving in brain laterality and whole brain is required to figure out the related learning styles. Self-directed learning involved in the learning senses shows the problem-based learning associated to the brain function by emphasizing the balanced brain utilization which is known as whole brain. These research results showed the successful whole brain learning is closely associated with elevated auditory learning and elevated visual learning in sensorimotor brainwave rhythm (SMR) while it shows the close association with elevated kinesthetic and elevated visual learning in beta brainwave rhythm.

This research attempted to find out any implications for strategies to design and develop the connections between the activities of the brain function and the fields of English learning (dictation, word level, speaking, word memory, listening). Thus, in developing the brain based learning model for the English education, attempts need to be made to help learners to keep the whole brain toward learning. On this point, this study indicated the significant results for the exclusive brain location and the brainwaves on the each English learning field by the quantitative EEG analysis. The results of this study presented the guidelines for the balanced development of the left brain and the right brain to train the specific site of the brain connected to the English learning fields. In addition, whole brain training model is developed by the quantitative EEG data not by the theoretical learning methods focused on the right brain training.

The purpose of this study is to provide some necessary baseline data to the information prodigy related research through the study on the brain left/right tendency of information prodigies. Subjects were 298 gifted students(59 information, 79 mathematics, 80 science, 40 invention, 40 social science) and 114 general students summing up 412 in the schools of Daejeon metropolitan area. 'Brain Tendency Test' developed by Torrance and modified by Ko in Korean was used as a tool to measure the prodigies' brain tendencies. Data analysis has been done with the $x^2$ test of frequency with the alpha = .05. The results of this study are as follows. 1) The information gifted students have tendencies of utilizing right brain hemisphere at the most, both left/right brain(whole brain) utilization at the second, and left brain utilization at the last. 2) There was statistically no difference between information prodigies and general students in the left/right brain tendency. 3) There was statistically mild evidence to support the notion that there are some differences in the brain tendency between the group of information prodigies and the group of other area of the prodigies. The degree of inclination to utilize the whole brain hemisphere for the prodigies of the other area was the highest compare to other left/right brain utilization while the information prodigies tend to utilize the right brain hemisphere at the most. 4) The female information prodigies have tendencies of utilizing while brain area at the most, right brain utilization at the second, and left brain utilization at the last contrary to the brain utilization tendencies in the male information prodigies which are the same as the brain utilization tendencies of the information prodigies. However there was no difference in brain tendencies statistically between the two groups since the female subjects were too small.

Objective : Multisensory integration (MSI) is the essential process to use diverse sensory information for cognitive task or execution of motor action. Especially, visual and somatosensory integration is critical for motor behavior and coordination. This study was designed to explain spatial and temporal characteristics of visual and somatosensory integration by neurophysiological research method that identifies the time course and brain location of the SI process. Methods : Electroencephalography (EEG) and event-related potential (ERP) is used in this study in order to observe neural activities when integrating visual and tactile input. We calculate the linear summation (SUM) of visual-related potentials (VEPs) and somatosensory-related potentials (SEPs), and compared the SUM with simultaneously presented visual-tactile ERPs(SIM) Results : There were significant differences between the SIM and SUM in later time epochs (about 200-300ms) at contralateral somatosensory areas (C4) and occipital cortices (O1&O2). The amplitude of the SIM was mathematically larger than the summed signals, implying that the integration made some extra neural activities. Conclusion : This study provides some empirical neural evidence of that multisensory integration is more powerful than just combing two unisensory inputs in the brain and ERP data reveals neural signature relating to multisensory integrative process. Since this study is preliminary pilot study, larger population and criteria are needed for level of the significance. Further study is recommended to consider issues including effect of internally-driven attention and laterality of interaction to make the evidence by this study solid.

신경과 의사들은 실제 임상에서 환자들에게 대뇌피질감각의 이상 여부를 알기 위해 손바닥에 숫자나 문자를 쓰게 하여 알아 맞추게 하는 검사를 시행한다. 손바닥에 쓰여진 문자나 숫자를 인식하기 위해서는 몇 가지 단계의 인지과정이 필요할 것으로 생각된다. 첫번째로 손바닥에 닿는 감각을 인지해야 하고, 다음 단계로 이 감각들을 시공간적으로 통합하는 과정이 필요할 것이고, 이러한 정보들을 유지하면서 마지막 단계로 우리 머리 속에 있는 문자와 일치시키는 과정이 필요할 것이다. 본 연구에서는 위와 같은 가설 아래 각각에 해당할 수 있는 뇌영역을 밝히기 위해 기능적 뇌자기공명영상을 이용하였다. 손바닥의 일차적 감각을 인지하는 데는 일차감각영역이 활성화 되었고, 이차감각영역의 활성은 감각들의 시공간적 통합과 관련될 것으로 생각되었으며, 이것들을 유지하는 것은 작업기억의 하부구조인 시공간 그림판과 관련되는 영역이며, 문자를 일치시키는 과정은 브로카영역 부근의 활성과 관련되는 것으로 생각되었다. 위의 가설에 대한 추가검증 및 실제로 일어나는 인지과정에 대한 추가적인 연구가 필요할 것이다.

뇌파, 즉 뇌전도는 뇌에서 일어나는 전위의 변화를 기록하는 것이다. 이는 두개골의 두피에 전극을 부착하거나 뇌 표면 또는 뇌속에 전극을 삽입하여 기록할 수 있다. 종래에는 뇌파는 활동전위의 동기화와 통합의 결과로서, 어떤 피질 영역에서의 뉴론의 활동을 직접 반영하는 것이라고 생각되어 왔다. 그러나 EEG 활동에서 상당한 부분은 뉴론의 막전위에 기인하며, 특히 느린 시냅스 후 전위의 가중에 기인한다고 할 수 있다. 그렇지만 활동전위가 EEG에 전혀 공헌하지 않는 것은 아니다. EEG는 그 파형에 따라 동기화 또는 비동기화로 나눌 수 있는데, 그 근간을 이루는 뇌 구조물은 상이하다. 그리고 피질의 활동에서 유래한 EEG는 피질하 구조물에 의해서도 영향을 받는다. 이러한 EEG를 활용한 연구는 인간 정신 과정을 이해하는데 이바지하는 바가 클 것이다.

This Investigation was carried out to map the morphological development of serotonin-immunoreactive neurons in the larval brain of the cabbage butterfly, Artogeia rapae, during five larval stages. Both the first instar larva and the second instar larva contained twenty serotonin-immunoreactive (5-HTi) neurons in each brain. The fibres of 5-HTI commissure was interconnected to two cerebral hemispheres in both brains. However, the 5-HTi commissural fibres was Increased in number in the second-instar larva brain. In the brain of the second Insar larva these 5-HTi fibres formed rich arborization in contralateral neuropils, especially In the posterior parts of it. The third-Instar larva braIn, which Included twenty two 5-HTi neurons, had three groups of 5-HTi commissural fibres. In the fourth Instar larva, the number of 5-HTi fibres as well as 5-HTi cell bodies increased in the brain. The fifth-instar larva brain, which contained fifty four 5-HTi cell bodies, showed the largest number of 5-HTi cell bodies In developing larval brains. The 5-HTi fibres formed richest commissural fibres and some of them run parallel to anteroposterior axis.
