The present study investigated effect on saccadic reaction time after repeated neck flexion. Twelve healthy young subjects participated in this experiment, in which eye movement task was pro-saccade and anti-saccade. Before the neck flexion movement, saccadic reaction time at the rest neck position for 30 s was measured three times with a 30-s rest between each measurement. Twenty-degree neck flexion was repeated twelve times for 120 s. After the neck flexion movement, above-mentioned saccadic reaction time was measured five times. In both saccadic tasks, reaction time in the first trial after the neck flexion movement was significantly shorter than that before the flexion movement. The shortening time was significantly larger in the anti-saccade than in the pro-saccade. These suggested that after the repeated neck flexion movement, the saccadic reaction time decreased due to persistent enhancement of the non-specific brain activation, and the larger shortening effect was found in the anti-saccade regulated by higher nervous system.

This study was the examination of the sustained effects of the autonomic nerve response due to the difference in the posture of the supine and the standing after the acupuncture method of the "skin / subcutaneous tissue, exhalation phase, sitting position". The subjects were 11 healthy male college students without medication and smoking habits (age 19.6 ± 1.0 years old, height 172.1 ± 4.1 cm, body weight 70.4 ± 4.3 kg). Cardiac autonomic nerve function was measured by measuring electrocardiogram and analyzing by spectral analysis of heart rate variability. In the evaluation by spectral analysis, the high frequency component HF (0.15 - 0.40 Hz) and the low frequency component LF (0.04 - 0.15 Hz) were measured, and HF component was used as a cardiac parasympathetic function and LF / HF component was used as an index of cardiac sympathetic function. HR and HF components showed no significant change at standing posture with passage of time after the acupuncture stimulation. However, HR and HF components showed significant change at supine posture with passage of time after the acupuncture stimulation, and enhanced the cardiac parasympathetic function. Furthermore, significant increase of LF / HF component was observed between 5 minutes and 25 minutes after the stimulation in the supine position. From these results, it was obvious that the sustained effects of acupuncture stimulation in the enhancement of cardiac parasympathetic function was caused by supine posture. Moreover, it was suggested that this acupuncture method may be enhance both cardiac parasympathetic and sympathetic nerves.

This study described the development of the scale for measuring felt shoulder stiffness (SMFS). The questionnaire was 28 items selected from previous studies.  The factor analysis was conducted on responses from 506 students, and three factors were extracted and were identified: I) Numbness and a prickle; II) Dull pain of a deep part; III) Sense of congestion. All these factors had high degrees of internal consistency.  The scores of the “Numbness and a prickle” were significantly correlated with the Hostility action scores (r = 0.17). On the other hand, the scores of the “Dull pain of a deep part” were non-significantly correlated with the Hostility action scores, but were significantly correlated with the Depression scores (r = 0.27), and Anxiety scores (r = 0.27). The scores of the “Sense of congestion” were significantly correlated with the Hostility action scores (r = 0.24), the Depression scores (r = 0.23), and Anxiety scores (r = 0.16).  These results suggest that SFMS may be a reliable instrument for assessing shoulder stiffness in Japanese.

Near-infrared red spectroscopy (NIRS) is a noninvasive method that uses changes in cerebral blood volume (CBV) to measure relative changes in tissue concentration of oxygenated, deoxygenated and total hemoglobin. We used this technique to determine the cortical activation area during Japanese grammatical processing. To assess the relative changes in total hemoglobin, local changes in near-infrared absorption were measured simultaneously from seven points in both hemispheres. Nine subjects were presented target stimuli, and were asked to decide whether the attendant particle was “ga” or “wo” in Japanese grammatical tasks (experimental conditions), and whether the relative position was “front” or “back” in positioning tasks (baseline and control conditions). To control subvocal rehearsal and conceptual driven processing, the same Kanji character was presented visually as a target in the experimental and control conditions. Total hemoglobin increased in Broca's area when subjects made judgments in Japanese grammatical tasks, compared to positioning tasks. These results suggested that the task of deciding particles in Japanese grammatical processing might be an effective and objective method to assess language disorders.

This study aimed to clarify the correlation between snacking behavior and psychological stress in female university students and thereby contribute to health support measures. A questionnaire survey was conducted to examine household living arrangements, snacking behavior (consumption of confectionery and snacks), and psychological stress stemming from interpersonal relationships or the demands of study, etc. of students from four universities in Japan. The survey was conducted yearly for 3 years (following multiple sections of the population from the first to third year), and 81 female students were valid respondents. Interpersonal stress scores were positively and significantly correlated with several items of snack frequency scores by time of day and snack frequency scores by situation (i.e., snacking alone, with friends, before/after classes or other events, and instead of a meal). In their first year, the students with high interpersonal stress showed a high total frequency of snacking in the morning, in the afternoon, or at night or snacking alone, which was more common among students living alone. In their second year, the students with high interpersonal stress showed a higher frequency of snacking alone. In their third year, the students living alone and with high interpersonal stress showed a high total frequency of snacking in the morning, in the afternoon, or at night; before or after classes or other events; and instead of a meal. It was found that the higher the degree of personal stress among female university students, the higher the frequency of their ingestion of confectionery and snacks.

In the study of brain function, several recording methods are employed. The advantage of an electroencephalogram (EEG) is its high temporal resolution. Time-frequency analysis of EEG data can provide activity changes in the frequency band of millisecond-order. Beta band activity is believed to reflect information processing in the cortico-cortical connection. Therefore, we studied beta band changes in cortical oscillatory activity in the cerebral cortex in order to investigate changes in decision-making and inhibition during a visual oddball task. Eleven right-handed healthy subjects participated in this study. In the oddball task, the subjects were required to press a button when the target stimulus (go condition, 20% probability) was presented, whereas they were required to withhold their response when the standard stimulus (no-go condition) was presented. EEG data were recorded from the scalp using 128 channels. The data were analyzed by time-frequency analysis for each go and no-go condition. In both conditions, an increase in the beta band activity of approximately 15 Hz was observed in the frontal association area, beginning after stimulation, and this increase was observed in the left motor association area. The duration was clearly shorter in the no-go condition than that in the go condition. These results suggest that an increased beta band activity in the frontal association area may represent integrative processing of visual information and decision-making in both conditions, whereas it indicates inhibition in the no-go condition. Moreover, the shorter beta band activity in the motor association area during the no-go condition indicates increased GABA-mediated inhibition.

The purpose of this study was to evaluate the effects of astaxantin(ACT)ingestion on exercise-induced physiological functions. In this experiment we planned to investigate the autonomic nervous system(ANS)and the respiratory metabolism during different exercise intensities in subjects taking astaxantin and those taking placebo. The design of this experiment was a double-blind crossover study.   Eighteen male volunteers(35.8±4.51 years of age)took ACT or placebo(CON)capsule daily for two weeks. Exercise stress tests were done before and after the ingestion period. The exercise load was in the form of running exercise on a treadmill at intensities of 30%, 50% and 70% of maximum heart rate(HRmax).Heart rate variability(HRV),expired gases analysis and blood biochemical parameters were measured. Sympathetic nervous activity(SNA)and parasympathetic nervous activity(PNA)were estimated from the pattern of power density in three frequency ranges on the power spectrum.   During the exercise at an intensity of 70% HRmax, CVRR and HF/TF increased significantly(p<0.05)after ACT ingestion. Additionally, VE decreased significantly(p<0.05)during exercise at 70% HRmax after ACT ingestion. These data indicated that after ACT ingestion, SNA was decreased and PNA was enhanced during exercises at 70% HRmax. Furthermore LDL cholesterol decreased markedly after exercise(p<0.05)and respiratory quotient decreased during exercise. These results suggest that ACT may contribute to enhancement of lipid metabolism. Decrease of respiratory parameters may indicate augmentation of the efficacy of exercise in energy metabolism.
