     View Summary

    This study examines the early development of cultural differences in a simple, embodied, and intersubjective engagement between mothers putting down, picking up, and carrying their infants between Japan and Scotland. Eleven Japanese and ten Scottish mothers with their 6- and then 9-month-old infants participated. Video and motion analyses were employed to measure motor patterns of the mothers' approach to their infants, as well as their infants' collaborative responses during put-down, pick-up, and carry phases. Japanese and Scottish mothers approached their infants with different styles and their infants responded differently to the short duration of separation during the trial. A greeting-like behavior of the arms and hands was prevalent in the Scottish mothers' approach, but not in the Japanese mothers' approach. Japanese mothers typically kneeled before making the final reach to pick-up their children, giving a closer, apparently gentler final approach of the torso than Scottish mothers, who bent at the waist with larger movements of the torso. Measures of the gap closure between the mothers' hands to their infants' heads revealed variably longer duration and distance gap closures with greater velocity by the Scottish mothers than by the Japanese mothers. Further, the sequence of Japanese mothers' body actions on approach, contact, pick-up, and hold was more coordinated at 6 months than at 9 months. Scottish mothers were generally more variable on approach. Measures of infant participation and expressivity indicate more active participation in the negotiation during the separation and pick-up phases by Scottish infants. Thus, this paper demonstrates a culturally different onset of development of joint attention in pick-up. These differences reflect cultures of everyday interaction.

  • Enhancement of Information Transmission with Stochastic Resonance in Hippocampal CA1 Neuron Models: Effects of Noise Input Location and Its Power Spectrum

    川口港, 簑弘幸, 百瀬桂子, D. M. Durand

    Transactions of Japanese Society for Medical and Biological Engineering   49 ( 1 ) 176 - 184  2011.01  [Refereed]

     View Summary

    Stochastic resonance (SR) is a phenomenon whereby detection of sub-threshold signal is improved by additive background noise in nonlinear systems. It has been unclear how this phenomenon is affected by the characteristics of background noise. In this paper, we investigate the effects of background noise characteristics on information transmission in a realistic hippocampal CA1 neuron model, i. e., the effect of input locations of the background noise and the influence of power spectra of the background noise. Using the computer simulation, the random sub-threshold input signal generated by a filtered homogeneous Poisson process was applied to a distal portion of the apical dendrite, while the background noise having a 1/fβ(β=0, 1, 2) power spectrum generated by a fractional integration was further applied to a variable location to investigate the effects of background noise input location on information transmission. Our results showed that SR was observed as the information rate reached a maximum value for optimal noise amplitude. The results also showed that the background noise input location and the coefficient β did not alter the maximum information rate generated by SR. The noise amplitude required to the maximum information rate increased when the noise input location was set at distal or the coefficient β was approached to zero from two. It is concluded that the variance of the noise having a frequency component of less than 200 Hz can play a key role in the information processing of sub-threshold signal transmission in the hippocampus.

  • Relationship between the binary kernels of visually evoked potentials and the visual responses on the magnocellular and parvocellular pathways

    K. Momose

    METHODS OF INFORMATION IN MEDICINE   46 ( 2 ) 169 - 173  2007  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Objectives: To investigate the nonlinear characteristics of visual evoked potentials (VEPs), and their correlation with the visual responses on parvocellular and magno-cellular pathways. First and second-order kernels of the VEPs elicited by several checkerboard patterns were estimated, and their relations to the visual pathway responses were investigated.
    Methods: VIPs elicited by checkerboard pattern (0.5, 1.0, 2.0 and 4.0 c/d) alternating based on pseudorandom binary sequence were measured, and their binary kernels were calculated. First and second-order binary kernels were compared with amplitudes of the steady-state VIPs (S-VEPs) to pattern reversal stimulation with a constant temporal frequency (4, 8,12,16, and 32 Hz).
    Results: Positive peak latencies at 150 ms (P150) of second-order first and second slices were correlated with S-VEP amplitude for higher temporal frequencies, indicating that the first and second slices reflect the response of the magnocellular. However, for second and third slices, their amplitudes were partially correlated with 4-16 Hz S-VEP, and this indicated that the second slice contains both magno- and parvo-cellular pathway responses. P150 latencies of third slices were correlated with S-VEP for lower temporal frequencies, indicating that third slice reflects the response of the parvocellular pathway.
    Conclusions: The lower slices of second-order binary kernels reflect the response of the magnocellular pathway and the higher slices reflect those on the parvocellular pathway in the human visual system of VIPs.

  • Characteristics of first and second order kernels of Visually Evoked Potentials elicited by pseudorandom stimulation

    DOCUMENTA OPHTHALMOLOGICA   108 ( 2 ) 157 - 163  2004.03  [Refereed]

     View Summary

    The characteristics of the first and the second order kernels of the visually evoked potentials (VEPs) elicited by pseudorandom binary sequence (PRBS) stimuli were investigated. VEPs were recorded from six eyes of four normal volunteers. The effects of stimulus luminance on the latency and amplitude of the first and the second order kernels were determined. The temporal interactions of transient VEPs elicited by single and double pulse stimuli were compared with the first and the second order kernels of the PRBS-VEPs. The correlation coefficient between the logarithm of the stimuli luminance (log I) and VEP amplitude of the first order kernels was 0.45 (p<0.05), and that between log I and P1 latency was -0.62(p<0.005). The second order kernels were not equal to the temporal interactions of the responses. However, the latency of the negative peak of the fourth slice was similar to the temporal interaction to double pulse stimulation with an inter-stimulus interval of 40 ms. An inhibitory component at 40 ms following the first stimulus was detected in the analysis of both PRBS-VEPs second order kernel and transient VEPs. This function may help to increase the frequency of critical flicker fusion in normal subjects.

    Infant picking-up from the floor was longitudinally observed at 1.5, 3, 5, and 7 months of infants' age. Mother's holding patterns changed after the infant's head held up steadily, and the speed of picking-up significantly increased at 3 months. Analysis by a motion-capture system also indicated an increase of speed in maternal manual approach with the infants' age.The mothers' sense of difficulty in their own holding was correlated with the paucity of the infants' active participation in the holding at 3 months, whereas it was correlated with the mothers' negative feeling in holding at 5 months

  • 視覚誘発電位の非線形システム解析による運動視の神経機構の解明とその臨床応用

    2013  

     View Summary

    視対象の動きの知覚(検出)を行う運動視に関わる脳機能を,簡易計測可能な視覚誘発電位(VEP)を利用して明らかにすることを目的とした.本検討では,運動視のメカニズムに関する研究の整理と,それらを踏まえての刺激系列とVEP分析方法の見直しを行った.加えて,VEPを精度よく記録するためにアーチファクトの影響の確認を行い,測定環境整備を行った.当初の研究計画では,VEPに対して非線形システム解析を適用することとしたが,文献調査と予備実験を踏まえて,刺激系列と分析方法を変更した.非線形システム解析に適した刺激系列では運動残効などの影響が大きく,適切な分析が行えないことが明らかとなったためである.加えて,そこで,視対象の動きの方向の変化の検出に目的を絞り,2つのパッチの点滅による仮現運動(Phi)を刺激に採用することとした.このパッチの点滅周波数を固定することによって,Steady-state型視覚誘発電位(SSVEP)を測定することとした.加えて,一方のパッチのコントラストを反転させた運動方向錯視(reverse Phi運動)刺激についても測定を行うことで,運動方向とSSVEPの関係を検討した.刺激の運動方向は,運動エネルギーモデル(Adelson & Bergen, 1985)を用いて予測した.健常成人9名を対象として,128チャンネルの高密度脳波の計測を行,予測された運動方向とSSVEPの位相に相関が見られた.具体的には,通常の刺激(Phi)とコントラスト反転を伴う刺激(reverse Phi)に対するSSVEPの位相が反転(逆位相)となり,子の位相反転は後頭部から側頭部の領域に見られた.しかしながら,点滅に伴う輝度変化の影響もVEPには反映されているため運動視の検出においては課題が残された.今後は,コントラストの影響を排除できる正弦波縞刺激を用いて,比較的明瞭な運動方向知覚が現れる運動残効時のSSVEPの測定・分析を行う予定である.
