Characteristics of Event-related Potentials in Recognition Processes of Japanese Kanji and Sentences for Chinese Bilinguals

This paper investigates the recognition process of Japanese kanji and sentences for Chinese bilinguals and Native Japanese speakers (NJS), by analyzing the event-related potential (ERP) differences between the two groups while they visually recognized Japanese kanji and sentences. The results showed that no significant differences were found between the two groups while they recognized Japanese kanji, but significant differences were found in the Japanese sentences condition. The results demonstrated that the neural mechanisms of recognition processes of Japanese sentences including kana between the two groups were not identical. When recognizing ambiguous sentences, Chinese bilinguals' P600 only appeared over the right frontal lobe, reflecting that syntactic integration and revision of ambiguous sentences for Chinese bilinguals was related with the right hemisphere. The results showed, for Chinese bilinguals, the difficulty of Japanese language learning was the recognition and understanding of Japanese sentences with kana, not Japanese kanji. We would like to provide a scientific learning method for Chinese bilinguals to enhance their Japanese language learning efficiency from the aspect of brain science.


Effect of mood state on anticipatory postural adjustments.

Static postural control has been demonstrated to link with psychological state. However, the effect of psychological state on dynamic postural control remains unclear. In this study, we examined the effect of mood state on anticipatory postural adjustment (APA), one of the most important functions for dynamic postural control. Fourteen healthy male subjects performed unilateral arm elevation tasks after completing a Profile of Mood States (POMS) questionnaire. Mood state measured by POMS and the latency or amplitude of the APA in the ventral muscles (rectus femoris, tibialis anterior) of the lower limb showed significant negative correlations. The correlation between the mood state and APA amplitude in the soleus was found to be significantly positive. There were significant negative correlations between the mood state and reaction-time. These findings suggest that it is possible that dynamic postural control is affected by mood state.


Relationship between electromyogram and autonomic nervous system activity assessed by heart rate variability during static muscle contractions

静的運動時の心拍変動から見た交感神経緊張度と筋電図との関係

We determined heart rate(HR), blood presure(BP), integrated EMG, and autonomic nervous system activity(ANSA)assessed by heart rate variability during 6-min static brachial biceps contraction(SC)of 10% of maximum strength in ten subjects. There was a negative relation in increased HR and LF/HF, implying that parasympathetic activity affected a change in HR during SC. Subjects showed, however, different patterns in response to SC in HF and LF/HF. BP showed a large increase during SC in all subjects. These results indicated that ANSA might differ in heart and brachial vessel during SC.

Selective modification of somatosensory evoked potential during voluntary finger movement in humans

We examined changes in somatosensory evoked potentials (SEPs) during voluntary movement of fingers innervated by the stimulated nerve and those not innervated by the stimulated nerve and the relationship to the kind of movement modality. Analysis showed that the amplitude of most components at F3, C3', and P3, except for P45 at C3, N35 and P45 at P3, decreased during voluntary finger movement tasks. Further, we found that the components of P40 at F3, P45 at C3', and N35 at P3 were increased during the voluntary pulling movement of the second and the third digits compared to those during the voluntary pushing movement of the fourth and the fifth digits, whereas all other components were decreased at F3, C3', and P3. We also found that not all components of SEPs were decreased while some SEPs in middle latency were increased. In conclusion, we confirmed the selectivity in attenuation of the SEPs. Moreover, we noted an interesting finding that the selectivity of attenuation of the SEPs was most frequently observed in the N20, P30 (P25 at F3), N35 (N30 at F3), and P45 (P40 at F3) components at F3, C3', and P3.

Somatosensory evoked potentials following voluntary movement during upper arm compression

We examined the modulation of somatosensory evoked potentials (SEPs) during upper arm compression and following voluntary movement during upper arm compression. Most SEPs were significantly decreased, although some SEPs showed a slight, non-significant diminution. SEPs are mediated not only by myelinated fibers but also by mixed nerves and afferents from cutaneous, joints, and deep tissues, these being dependent upon the dorsal column-medical lemniscal system. Therefore, most of the diminution in SEPs found here may have been due to afferent occlusion from muscle, cutaneous, joints, and deep tissues, since normal SEPs are selectively modulated, corresponding to motor or mental tasks, regardless of whether gating is centrifugal or centripetal. In addition, the present experiments showed that all the SEPs at FZ, C3' and CZ were significantly decreased following voluntary movement at a pressure 25%-30% higher than the subject's systolic blood pressure. Comparing SEPs during upper arm compression and those following voluntary movement during upper arm compression at these pressures, we found that the SEPs at C3' were significantly diminished following voluntary movement during upper arm compression, with other SEPs showing slight, non-significant attenuation. In conclusion, it is possible that the diminution in SEPs following voluntary movement could be responsible for sensory inputs, however, when sensory inputs are present, centrifugal modulation would also be responsible for this diminution.

Threshold of the soleus muscle H-reflex is less sensitivity to the changes of excitability of the motoneuron pool during plantarflexion or dorsiflexion in humans

In the present study, we investigated whether weak (10% of maximal voluntary contraction) tonic dorsiflexion (DF) and plantarflexion (PF) affects the two conventional parameters used for evaluating the excitability of the soleus motoneuron (MN) pool, i.e. the ratio of the threshold of H-reflex to that of M-response (Hth:Mth) and the ratio of the maximal amplitude of H-reflex to that of M-response (Hmax:Mmax) in human subjects. The results showed that the Hmax:Mmax decreased during DF and increased during PF compared with that during rest, whereas no clear alteration was observed in Hth:Mth. These results are consistent with the scheme proposed by earlier workers, who have argued that neither inhibitory nor facilitatory effects of the conditioning stimulus apply to specific spinal reflex circuits occurring around the threshold of the test H-reflex. It is suggested, therefore, that the conventional use of the Hth:Mth ratio as a parameter reflecting the excitability of the MN pool should be reconsidered.

Attenuation of somatosensory evoked potentials immediately following rapid reaction mevement

We investigated the changes in the somatosensory evoked potentials (SEPs) and particularly which components of the SEPs altered immediately after rapid reaction movements. N20, P23, N35, and P45 components measured over the scalp were all attenuated except for the P45 component measured at CZ. Particularly, the N20 and P23 components were markedly attenuated at both C3' and CZ immediately following rapid reaction movements. N18 and N20 components are thought to represent thalamocortical and primary sensory cortex activities. Therefore, the present results suggest that following rapid reaction movements, the thalamocortical and primary sensory activities are significantly attenuated. Moreover, following rapid reaction movements, the onset of EMG activity preceded the afferent discharge of the muscle spindle. Therefore, it may be concluded that central factors were principally responsible for the attenuation of the SEPs immediately following rapid reaction movements.

Suppression of cerebral evoked potentials preceding rapid reaction movement

In this study we examined the gating of the cerebral evoked potentials during warning-imperative stimulus intervals and preceding the rapid movement. We also examined the possibility of the gating phenomenon occurring in the precentral cortex. The experiment showed that the amplitudes of cerebral evoked potentials increase at all C3 and CZ during the warning-imperative stimulus intervals. Therefore, it seems that gating does not occur within the central nervous system during warning-imperative stimulus intervals. Furthermore, we observed that preceding rapid movement, the amplitudes of the cerebral evoked potentials decreased at all C3 and CZ. In the present experiment, it does not seem that a peripheral mechanism plays a role in the rapid movement. Therefore, it can be concluded that the decrease in amplitude of the cerebral evoked potentials preceding rapid movement may be due to a central mechanism irrespective of afferent information. In addition, we confirmed that the amplitude of cerebral evoked potentials decreases considerably at the precentral cortex and that the attenuation in amplitude of cerebral evoked potentials is more pronounced over the CZ than over the C3.

Changes in cerebral somatosensory pathway accompanying reaction movements

The changes within central somatosensory pathways accompanying reaction movements were examined by subtracting the peak latency of the major response from the cervical area (14 msec.) from that of the primary cortical response (20 msec.) and also measuring the CNV which is dependent on the direction of the subject's attention and level of arousal. These parameters were measured before (at rest), during fast and slow reaction movements, and mental readiness to act. Analysis showed that the difference in N20-N14 potential latencies is the shortest during fast reaction movements and is shorter during movement tasks than during mental readiness and intention to act. Moreover, we confirmed that the CNV amplitudes are significantly higher during fast than during slow reaction movements and also that the difference in N20-N14 potential latencies decreases as the CNV amplitude increases. Accordingly, from the present results and a series of studies conducted by others, it may be concluded that not only are the changes in the central motor area confirmed by the movement-associated cerebral potentials but also those in the central somatosensory area occur prior to reaction movements.

RELATIONSHIP BETWEEN ALPHA-BLOCKING AND SLOW POTENTIAL CHANGES PRECEDING REACTION MOVEMENT

反応動作のα-blochingと緩電位変動との関連について

In order to investigate the association of alpha-blocking with motor set under the condition of simple reaction movement, the scalp distribution of alpha wave envelope recorded by averaging method was compared with that of slow potential changes. The results were as follows.
1) The slow potential changes (readiness potential, early and late component of CNV) were large over the central and frontal area. The readiness potential was larger over the contralateral than the ipsilateral central motor area, while the early component of CNV showed bilateral spread. The late component of CNV showed the similar scalp distribution to that of readiness potential, but the latter was much more lateralized.
2) The alpha-blocking was bilaterally symmetrical over the central and occipital area under the condition of photic stimulus without movement. But the alpha-blocking accompanying preparatory signal increased over the frontal and central area compared with control alpha-blocking, and was larger over the contralateral than ipsilateral central motor area.
3) The maximal alpha-blocking rate showed to correlate negatively with its latency under each condition. The difference in alpha-blocking rate at the onset of the imperative stimulus between reaction movement and control showed to correlate negatively with reaction time.
From these findings, it seems that alpha-blocking accompanying preparatory signal reflects not only input system but also readiness potential component, and that in temporal respect alpha-blocking increases at the onset of movement.

単純反応動作において, 予告刺激に伴うα-blockingの変動と動作の準備状態との関連性を明らかにするために平均加算法によって得られたα波包絡線と緩電位変動の頭皮上分布に関して比較検討を行った．結果は以下のとおりであった．
(1) 緩電位 (準備電位, CNV早期および後期成分) は中心野, 前頭野に優位であった．準備電位は同側中心野と比べ対側中心野で優位であったが, CNV早期成分は両側性に出現した．CNV後期成分は準備電位と類似した頭皮上分布を示したが, 後者の方がより非対称性が著明であった．
(2) 動作なしの光刺激によるα-blocking (コントロール) は, 中心野, 後頭野とも両側性に生じたが, 反応動作の予告刺激に伴うα-blockingはコントロールと比較すると, 前頭野, 中心野で著明であり, 同側中心野に比べ対側中心野で優位に生じた．
(3) 同一条件下ではα-blocking率が増大するほどその潜時は短縮するが, 反応動作一条件をコントロールと比較するとα-blocking率が増大しても潜時は逆に延長し, 動作時まで相対的にα-blockingが維持された．さらにまた駆動刺激が呈示される時点でのα-blocking率1が, コントロールの同時点でのα-blocking率に比べて増大するほど反応時間は短縮した．
以上のことから, 予告刺激に伴うα-blockingは感覚刺激の入力系のみならず, 準備電位成分も反映し, 経時的には動作遂行時でのα-blocking率が増大することが示唆された．

The relationship of muscular peak changes with accuracy in an over-arm throwing task

Many studies regarding throwing tasks have focused on spatial and temporal characteristicsof individual muscles. However，the special relationship between muscles is not entirely clear when itcomes to describing human skilled movement.The purpose of the present study was to establish therelationship betwccn accuracy in a throwing task (performance) and electromyograms (EMGs) as ameasurement of coordination ability in an over-arm throwing task. We recorded surface EMGs for 17muscles from the upper limb, trunk，and lower limb during throwing task. The task was to throw to atarget，and throwing perfonmance was assessed by an accuracy score. This was conducted to examinethe relationship between performance and the peak changes in each EMG. The results showed that theactivity peaks of the biceps brachii， extensor digitorum， and right rectus femoris were negativelycorrelated with performance. Regarding inter-peak periods, the difference in peak latencies between thebiceps brachii and the rectus abdominis was correlated with performance，as was the difference betweenthe flexor carpi radialis and the biceps brachii. These results show the ability of muscles to coordinatein an over-arm throwing task.


Effects of stretch-shortening cycle exercise to exhaustion on the contractile properties of the triceps surae muscle and injury-related parameters

疲労困憊に至る伸張-短縮サイクル運動が下腿三頭筋の収縮特性及び損傷指標に及ぼす影響

The repeated heel-raiseis a typical stretch-shortening cyc1e (SSC) exercise. The exercise is not only performed in resistance training but also used for evaluating muscular strength in c1inical settings. The present study was undertaken to investigate the effect of repeated heel-raise exercise to a volitional exhaustion on contractile properties of the triceps surae muscle and parameters reflecting muscle injury.Five Healthy university students with no orthopedic disorders served as subjects. Each subject performed two exercises. ln SSC condition，the subjects repeated the SSC exercise every 2 seconds to volitional exhaustion. ln the IS0 condition，they repeated the same number of an isometric exercise as that of the SSC exercise.In the SSC condition，the subjects exhausted after repeating the exercise 28.6 times. At exhaustion，maximal torque developing capacity decreased significantly and the decrease was accompanied by a tendency of a lower median power frequency of the EMG signals. A significantly higher lactate concenlration was also observed. On the other hand，the ISO exercise induced no significant changes in these parameters.In the SSC condition，the decreased maximal torque developing capacity at exhaustion remained one hour and even one day following the exhausting exercise. The circumference of the lower extremity became larger significantly at exhaustion as compared with the pre-exercise values and remained higher one hour and one day after the exercise. The pressure threshold for pain in the medial head of the gastrocnemius muscle and the muscle-tendon junction of the triceps surae muscle became significantlylower compared with pre-exercise value one hour or one day following the exercise. Muscle painevaluated using visual analog scale f1uctuated and the higher value was observed at exhaustion and one day after SSC exercise. ln the ISO condition，no significant changes in these parameters were observed.The results of the present study indicated that the SSC exercise had more profound effects oncontractile properties， myo-electrical signals and injury-related parameters than the ISO exercise.Furthermore, the results suggest that，even in a relatively small number of repetitions，repeated heel-raise, at ypical SSC exercise，induces as light muscle injury.
