  • ChongMyeong-Tang (CMT) have been used clinically to treat patient with amnesia and dementia. In addition, CMT have been also used for examinee to improve learning ability in Korea. This study was designed to investigate the effects of Gagam-ChongMeong-Tang (GCMT) on cognitive dysfunction recovery after ischemic brain injury in rats. Rats were divided into three groups; (1) normal, (2) commercial diet after ischemic brain injury (control), (3) CMT diet after ischemic brain injury (experiment). In our study, we carried out Morris water maze test for cognitive motor behavior test and immunohistochemistry study through the change BDNF in the hippocampus($7^{th},\;14^{th}\;day$). In Morris water maze test, cognitive motor function recovery was significantly increased in the experiment group as compared with control group on $7^{th}\;and\;14^{th}\;day$ day (p<0.01). In immunohistochemistric response of BDNF in the hippocampus, more immune reaction was investigated in the experiment group as compared with control group on $7^{th}\;and\;14^{th}\;day$. Especially more immune reaction was experimented $14^{th}$ day. These results imply that GCMT can play a role in facilitating recovery of cognitive function after ischemic brain injury in rats.

  • This study was conducted to explore the direction of culinary education based brain-based education with analysis of comprehensive research. Questionnaire was completed by frequency analysis, factor analysis, reliability analysis and regression analysis by using SPSS 21. The purpose of this study was to investigate the educational system for creative development through cooking sources and to develop brain-based learning theory, and thus to generate the characteristics and effects of the practice in culinary educational context. The basic principles of brain- based learning are brain plasticity, emotional brain, and ecological brain. Students need to be able to enrich their understanding of social interaction so that social brain's function will be activated through consistent and high-quality feedback. Likewise, students should be capable of collecting everything what they have learned. Defining main ideas and goal of the lesson, four factors were derived from development of competency, personality, application, and diversity. Regarding to the result of this study, the implications for the development of a brain-base program were suggested.

  • Objectives: We studied correlations between neuropsychological tests and perceptual disorder in patients with head trauma and psychiatric patients in order to explore the functional localization of brain in perceptual disorders. Methods: Halstead Reitan Neuropsychological Test Battery, Korean Wechsler Intelligent Scale, and Minnesota Multiphasic Peronality Inventory(MMPI) were administered to one hundred ninteen patients consisting of sixty nine psychiatric patients and fifty patients with brain damage. We tested the correlation between results of neuropsychological tests and peceptual disorder scale PDS) made from nine items related with perceptual disorder in MMPI. T-tests between twenty one higher scorers and seventeen lower scorers of PDS were also performed in the psychiatric group. Results: In brain damage group, significant correlations were found in tests related with function of frontal lobe such as category tests, trail making tests, tactual performance test, and fingertip number writing test, and significant correlations were also noted in the tests related with function of right hemisphere such as tactual performance test, performance, picture completion, picture arrangement and block design. Tests related with subcortical function such as digit symbol test, arithmetic and digit span were signigicantly correlated, too. In psychiatric group, there were significant differences of PDS in the tests related with function of right hemisphere such as picture completion, block design, and right laterality index, and in the tests related with function of left hemisphere such as comprehension, vocabulary, and similarities. Conclusion: Perceptual disorder seems to be related with functions of frontal lobe, right hemisphere, and subcortex in both groups. In a psychiatric group, left hemisphere may be also partially related with perceptual disorder.

  • In order to develop silk peptide (SP) preparations possessing cognition-enhancing effect, several candidates were screened through in vitro assays, and their effectiveness was investigated in facilitated brain aging model rats. Incubation of brain acetyl-cholinesterase with SP-PN (1-1,000 ${\mu}g/ml$) led to inhibition of the enzyme activity up to 35%, in contrast to a negligible effect of SP-NN. The expression of choline acetyltransferase (ChAT) mRNA of neural stem cells expressing ChAT gene (F3.ChAT) was increased by 24-hour treatment with 10 and 100 ${\mu}g/ml$ SP-NN (1.35 and 2.20 folds) and SP-PN (2.40 and 1.34 folds). Four-week subcutaneous injections with D-galactose (150 mg/kg) increased activated hippocampal astrocytes to 1.7 folds (a marker of brain injury and aging), decreased acetylcholine concentration in cerebrospinal fluid by 45-50%, and thereby impaired learning and memory function in passive avoidance and water-maze performances. Oral treatment with SP preparations (50 or 300 mg/kg) for 5 weeks from 1 week prior to D-galactose injection exerted recovering activities on acetylcholine depletion and brain injury/aging as well as cognitive deficit induced by D-galactose. The results indicate that SP preparations restore cognitive functions of facilitated brain aging model rats by increasing the release of acetylcholine, in addition to neuroprotective activity.

  • Drosophila melanogaster (fruits fly) is a representative model system widely used in biological studies because its brain function and basic cellular processes are similar to human beings. The whole head of the fly is often used to obtain the key function in brain-related diseases like degenerative brain diseases; however the biomolecular distribution of the head may be slightly different from that of a brain. Herein, lipid profiles of the head and dissected brain samples of Drosophila were studied using electrospray ionization-mass spectrometry (ESI-MS). According to the sample types, the detection of phospholipid ions was suppressed by triacylglycerol (TAG), or the specific phospholipid signals that are absent in the mass spectrum were measured. The lipid distribution was found to be different in the wild-type and the microRNA-14 deficiency model ($miR-14{\Delta}^1$) with abnormal lipid metabolism. A few phospholipids were also profiled by comparison of the head and the brain in two fly model systems. The mass spectra showed that the phospholipid distributions in the $miR-14{\Delta}^1$ model and the wild-type were different, and principal component analysis revealed a correlation between some phospholipids (phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatidylserine (PS)) in $miR-14{\Delta}^1$. The overall results suggested that brain-related lipids should be profiled using fly samples after dissection for more accurate analysis.

  • Objectives : Ohyaksungi-san(Wuyaoshunqi-san) has been used for many years as a treatment for cerebrovascular diseases in Oriental medicine. This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san) on cognition and motor function recovery after ischemic brain injury, and also the expression of BDNF in hippocampus. Methods : This study was designed with 4 subgroups to evaluate the effects of Ohyaksungi-san(Wuyaoshunqi-san). As control groups, group I has no treatment during 1 week after ischemic brain injury and group II has no treatment during 2 weeks after ischemic brain injury. As experimental groups, group III has been treated with Ohyaksungi-san(Wuyaoshunqi-san) during 1 week after ischemic brain injury and group IV have treated with Ohyaksungi-san(Wuyaoshunqi-san) during 2 week after ischemic brain injury. Each group has been examined by tests as follows, neurological motor behavioral tests, cognitive motor behavior test and histological test. Neurological motor behavior tests consisted of limb placement test, beam-walking test and horizontal wire test. Cognitive motor behavior test was performed by using Morris water maze. In the histological test, TTC(2,3,5-triphenylteterazolium chloride) staining, hematoxylin & eosin staining, and immunohistochemical staining were used. Results : 1. The tests for motor function recovery change had significantly good result in the experimental groups as compared with control groups(p<.05). 2. The Morris water maze test on cognition also had significantly good result in the experimental groups as compared with control groups(p<.05). 3. In the immunohistochemical staining for the expression of BDNF in hippocampus, more immune reaction was investigated in the experimental groups as compared with control groups. Especially group IV has the greatest immune reaction. Conclusions : Ohyaksungi-san(Wuyaoshunqi-san) has good effects on cognition and motor function recovery after ischemic brain injury, and also the expression of BDNF in hippocampus.

  • This study was performed to identify the effects of the improvement of brain function by CST on the elderly with the 2nd or 3rd grade of long-term care insurance service. A quasi-experimental design using a nonequivalent control group, pre-post test was used. A total of 12 elders (6 in the experimental group and 6 in the control group) were recruited. Upledger CST(10-Step Protocol) was performed on each subject for 50 minutes per session, once a week, for a total of 8 treatments over an 8 week period from Jan to Feb 2015. The brain function quotient was measured before the 1st CST and after the last CST by portable EEG measurement device using a 2 Channel neuro-feedback system. The data was analyzed by SPSS (Ver. 18.0) program. After CST intervention, the attention quotient (AQ), level of tension, anti-stress quotient (ASQ), emotion quotient (EQ) and brain quotient (BQ) of the experimental group was significantly better than that of the control group. These results showed that the CST was effective in reducing the level of fatigue by the AQ, increasing the physical and psychological stress relief by the ASQ, emotional balance by the EQ, and improving the total brain function by the BQ. Therefore, CST can be used as an effective intervention for improving the health and brain function of the elderly in health facilities.

  • Functional near-infrared spectroscopy (fNIRS) is a noninvasive optical imaging technique that indirectly assesses neuronal activity by measuring changes in oxygenated and deoxygenated hemoglobin in tissues using near-infrared light. fNIRS has been used not only to investigate cortical activity in healthy human subjects and animals but also to reveal abnormalities in brain function in patients suffering from neurological and psychiatric disorders and in animals that exhibit disease conditions. Because of its safety, quietness, resistance to motion artifacts, and portability, fNIRS has become a tool to complement conventional imaging techniques in measuring hemodynamic responses while a subject performs diverse cognitive and behavioral tasks in test settings that are more ecologically relevant and involve social interaction. In this review, we introduce the basic principles of fNIRS and discuss the application of this technique in human and animal studies.
