Shipping Along with the aging of the total population, its importance is greater cause of stroke, which is one of the diseases are listed cerebral perfusion is about 80%,.ie that the flow of blood flowing to the brain is reduced as the cause. One of the most typical prophylaxis and treatment of these stroke is to enhance cerebral perfusion. There are several ways to increase cerebral blood flow are a therapy through drugs, through surgery and invasive NeuroFlo. NeuroFlo is to insert a catheter to which a balloon is attached into a patient's artery. However, since the method of enhancing conventional cerebral perfusion have been conducted mainly in invasive method, giving a burden to the patient, the problem of inducing a number of complications were noted. In this paper, an attempt to supplement the shortcomings of such invasive brain perfusion increase method, to provide a device to enhance the non-invasively brain perfusion.

Treatment for cerebral blood flows is one of the most important treatments for cerebral infarction. There is a concern that the increasing number of cerebral blood flow treatments can cause multiple complications as it is invasive. To compensate for these problems, recently non-invasive cerebral blood flow increases have emerged. However, the current implementation of the non-invasive cerebral blood flow sensor raises the question of speed and accuracy. In this theses, the system aims to minimize the final cortical damage to the cerebrum by implementing a system in a completely different manner to complement the disadvantages of the existing non-invasive cerebral blood flow device. The system measure the PI of the limbs while simultaneously pressing limbs. Blood flow rate is carried out indirectly by increasing blood flow to peer pressure through the limbs in which the PI eips below a certain level. This can be used selectively in patients to increase blood flow.

One of the treatments and preventions of strokes such as ischemic stroke is to increase cerebral blood flow. This aims to minimize the size of the stroke by increasing the quantity of blood to the cerebral region circuitously. Several ways to increase cerebral blood flow are a therapy though drugs and through surgery. However these invasive method giving a burden to the patient, the problem of inducing a number of complications were noted. In this thesis, we propose a non-invasive brain flow enhancer to complement the disadvantages of such invasive treatment methods. To compensate for the shortcomings of the existing devices, the patient's blood pressure is accurately measured and the blood pressure is applied to the extremities, thereby increasing blood flow to the femoral region to produce blood clotting treatments. Although somewhat inadequate blood flow increases compared to conventional devices, blood flow can be significantly increased, which can be selectively.

Several ways to increase cerebral blood flow are a therapy though drugs and through surgery.

In this thesis, we propose a non-invasive cerebral blood flow augmentation device to compensate for the disadvantages of these invasive treatments. To compensate for the shortcomings of the existing cerebral blood flow device, apply a positive measure of the patient's extremities to measure the blood pressure of the patient's blood pressure and conduct a frontal injection of blood flow to increase blood flow. Although somewhat inadequate blood flow increases compared to conventional devices, blood flow can be significantly increased, which can be selectively.

The clinical assessment of a patient with a cerebral lesion is not easy to physicians. Extensive neuropsycho-logical tests often need both skilled experience and some special tools. Some bedside tests equally provide valuable clues to localize cerebral lesion, when a clinician knows functional anatomy of cerebral hemisphere. In this article, several techniques used to evaluate cerebral cortical function will be introduced.

목적 : 이 실험의 목적은 경혈에 대한 침자극이 대뇌피질에 어떠한 영향을 미치는가에 대하여 체계적이고 객관적으로 증명하는 것이다. 방법 : 시각과 관련이 있는 광명(GB37), 청각과 관련이 있는 협계(GB43) 및 외관(SJ5)을 자극하고 fMRI를 통하여 대뇌피질의 활성정도를 관찰하였다. 결과 : 이들 경혈의 자극으로 시각과 청각과 관련된 피질의 활성이 나타났다. 자극에 의한 대뇌피질 활성을 fMRI를 통하여 고찰한 결과 특정한 경혈의 자극이 대뇌피질을 활성화시킨다는 사실을 알 수 있었다. 결론 : 치료 효과는 그 경혈의 자극에 의한 대뇌피질의 활성과 관련이 있음을 말하는 것으로, 경혈지극과 대뇌와의 상관성을 증명하는 것이다.

Curcumin plays a protective role in brain injury through its anti-oxidant and anti-inflammatory activities. Moreover, peroxiredoxin-5 exerts a protective effect against oxidative stress. The aim of this study was to investigate whether curcumin modulated the peroxiredoxin-5 expression in focal cerebral ischemic animal model. Middle cerebral artery occlusion(MCAO) was performed to induce cerebral ischemic injury in rats. Adult male rats were injected intraperitoneally with vehicle or curcumin(50mg/kg B.W.) 1 h after MCAO and cerebral cortex tissues were collected 24 h after MCAO. Photographs of hematoxylin and eosin staining showed that MCAO induced necrotic changes with scalloped shrunken form and apoptotic changes with nuclear chromatin condensations. However, curcumin treatment attenuated MCAO-induced histopathological changes. Moreover, this study clearly showed that peroxiredoxin-5 expression was decreased in MCAO operated animal with vehicle using a proteomics approach. However, this decrease in peroxiredoxin-5 expression was attenuated by curcumin treatment. Reverse-transcription PCR and Western blot analyses confirmed that curcumin treatment alleviated the MCAO injury-induced decrease in peroxiredoxin-5 expression(p<0.05). These results demonstrated that curcumin regulates peroxiredoxin-5 expression in MCAO animal model. In conclusion, our findings suggest that curcumin exerts a neuroprotective effect in cerebral ischemia by attenuating the MCAO-induced decrease in peroxiredoxin-5 expression.

Difference of individual character is defined Cerebral Hemispheric Model(CHM) to develop individual intellectual abilities in this paper. Component of preferred online-game is surveyed in accordance with individual character, and investigated for possible applications. An individual is classified with 2 modes of CHM that take charge of intellectual abilities; abilities is character, taste, personality decision-making and behavior patterns; that is closely related to creativity. Difference of game component could be investigated with correlation table of cerebral preference patterns (CPP) that was drawn up with survey. Individual brain preferences (IBP) became clear through preference of individual in the investigation, and suggested concept guide-line to develop other brain preferences. Thus, this study is able to realize from education game to a great variety of contents that base on the development of thinking-faculties as optimization of user preference, can be the basic data of self-development, to improve intellectual faculties as development of individual thinking preference.

The brains of adolescents experience rapid changes, which has been studied to prove relatedness between neuroanatomical properties and IQ. But, most previous studies infer the relatedness from purely cross-sectional data. This study not only measured the thickness of the cerebral cortex once, but traced its variability and the relatedness between IQ and this variability, which was presumed to be 75. Healthy adolescents (M=16yr. and 4month) were divided into 5-stage categories based on their intellectual ability and MRI scan was made twice every 6 months to measure the variablity of their cerebral cortex. As a result, a big difference in the variability of the cerebral cortex was shown based on their IQ. Three groups with an IQ of more than 120 showed a decrease in the thickness of the cerebral cortex in 11 brain regions, while two groups with an IQ lower than 120 showed an increase in the cerebral cortex thickness in 5 to 8 regions. It is presumed that the lower the IQ, the slower the maturation of the cerebral cortex.
