    A technique for nerve stimulation has been developed to elicit a single unidirectionally propagated action potential. A quasitrapezoidal stimulus current wave delivered through an asymmetric tripolar electrode effectively blocks propagation in one direction from the stimulus site. View full abstract»

    A previously reported stimulation technique which elicits a unidirectionally propagated nerve action potential has been evaluated with repetition rates from 10 to 100 Hiz. Block of propagation in one direction from the stimulus site was sustained up to 50 Hz with monophasic stimulation and 30 Hz with biphasic stimulation. The use of long stimulating pulses produces pronounced degradation of the block at high frequencies. View full abstract»

  • A Stochastic Approach to the Detection of Receptive Fields in the Visual System

    A statistical approach is developed for the detection of receptive fields of cells in the visual system. A spatiotemporal random pattern of light, composed of successive frame patterns, is used as a stimulation signal. A frame consists of N2 square elements: N rows and N columns. The brightness of each element is independent to one another and takes "light" or "dark" state. Shaped random patterns are defined in the spatiotemporal random pattern, and a list indicating the presence and absence of a defined feature pattern is made from the spatiotemporal random pattern. The receptive field is described in terms of the spatial response function based on a cross correlation between cell's reponse and feature signal (feature list). Consideration is given to feature parameters affecting on results. View full abstract»

    This paper discusses the design, implementation, and performance of a microprocessor-controlled moving chair for vestibular function testing. The device is simple enough to use for routine clinical testing yet has sufficient performance to pennit research on advanced clinical vestibular tests. Each test procedure is treated as a module in software (and hardware as necessary), and permits easy revision of protocols. View full abstract»

  • Computer-Based Calibration and Measurement of an EEG Data Acquisition System

    A two-part procedure is described for computer-based calibration and measurement of an EEG data acquisition system. The main innovation lies in the application of trains of computer-generated (sin t)/t time-domain "impulses" with theoretically known and nearly ideal spectral characteristics, to measure and periodically verify the complete in-band frequency and phase response of the system. If and only if homogeneity of channel response has been demonstrated to hold at all frequencies over channels and occasions, routine calibration of the system for each recording session can be effectively and quickly accomplished by equating system response under computer control at a single frequency, for example, through the use of a simple sine wave calibration signal. Thus, a strong technical foundation is provided for assuring instrumental reliability and validity in electrophysiological measurements. Illustrative results of the system-measurement procedure are presented, and mathematical and computational details are supplied in a technical Appendix. View full abstract»

  • Electrode and Electrolyte Impedance in the Detection of Bacterial Growth

    The growth of bacteria in culture was found to produce impedance changes between two metal electrodes which result from changes both in conductivity and electrode impedance. Predominant changes were found in the imaginary impedance component at low frequency. Linear ac impedance characteristics were found in the relation between real and imaginary impedance components before and during bacterial growth. This linear relation is consistent with characteristics of diffusion and electron exchange (oxidation-reduction) at the electrode. The measurement of impedance in this system was limited below 100 Hz by nonlinearity in the voltage-current relation. Bacterial growth was best detected with stainless steel electrodes at low frequency (100 Hz) and including the imaginary component of impedance. View full abstract»

    In this communication we discuss effects of load and day-to-day variation on the autoregressive integrated moving average (ARIMA) model for signals from the medial deltoid muscle. The movement consisted of 15 successive 90°abduction-adductions under several loading conditions for two normal subjects. In one case, the measurements were repeated over two consecutive days.

  • Oscillating Flow of a Viscous Compressible Fluid Through a Rigid Tube: A Theoretical Model

    The forced oscillation technique used to determine the impedance of the respiratory system has been modified by measuring, instead of pressure and airflow at the mouth of the subject, the transfer function over a rigid tube. An exact description of the aerodynamic characteristics of a cylindrical conduit is needed in this method. Therefore, a line model was developed, describing the tube as a pneumatic transmission line and taking into account the axial pressure losses, the gas compressibility, and the thermal conductivity of the tube wall. The quality of this model was verified by measuring velocity profiles at the end of an open tube at various frequencies. The agreement with the predictions of the model was satisfactory.

  • Analysis of Forces Transmitted by Upper Complete Dentures to the Supporting Tissue to Contribute to Better Denture Design

    In this communication, a denture cross-sectional rib through the molars is analyzed for the applied masticatory force transmission to the supporting tissue. The denture arch is analyzed in order to determine how the arch geometry and dimensions influence the manner in which the arch transfers the support forces and moments (which represent the masticatory loads) to the supporting tissue. The analysis is carried out for a circular denture arch conforming to a circular palatal section. Factors representing ratios of masticatory loads (in terms of forces acting at the arch supports) to the tissue-bearing pressure are presented as nomograms, for various denture arch dimensions.
