    Bioelectric current in one-dimensional tissues can be measured by using a room temperature amplifier and a wire-wound, ferrite-core toroid to detect the associated biomagnetic field. In this paper, the capabilities of such a toroid-amplifier system are discussed, with emphasis placed on the signal-to-noise ratio and the spatial resolution of the toroid. Use of this system for measuring current is ... View full abstract»

    Signal averaging the ECG to observe low level signals generated by His¿Purkinje system (HPS) has many disadvantages and has not been widely used. This is partly due to the inability to distinguish between atrial and HPS potentials within the PR segment. To more clearly observe the onset of the HPS activity, several leads with an esophageal electrode were studied and compared to a bipolar surface ... View full abstract»

    A simple and inexpensive method for measuring the extent and rate of shortening of single myocytes was developed. The image of a single cardiac myocyte was focused through a 10x objective of an inverted microscope and projected onto a linear photodiode array having 256 self-scanning elements. This array was used as an edge detector to define cell length. The output from the array was fed into a di... View full abstract»

    Memory impairment has been associated with a deficit in a functional component of attention termed "focused arousal." Short, aperiodic bursts of EEG activity in a narrow frequency band (36¿44 Hz) centered at 40 Hz have been established as an indicator of this state of "focused arousal." A measure of this 40 Hz EEG activity could be very useful in the diagnosis of different types of cognitive dysf... View full abstract»

  • Performance and Measures of Performance for Estimators of Brain Potentials Using Real Data

    Publication Year: 1986 , Page(s): 949 - 956
    Cited by:  Papers (9)

    A number of filtering and smoothing procedures have been proposed for estimating evoked brain potentials. Their common goal is to reduce noise further than averaging. A statistical method is proposed for comparing these estimators for real data, thereby avoiding the use of simulated data, which usually are not representative of the shapes encountered for signal and noise and might also rely on som...

  • Criteria for Optimal Averaging of Cardiac Signals

    The averaging process is modeled as a linear system whose low-pass filter characteristics are determined by the degree in temporal misalignment of signals. Assuming the errors in temporal alignment of successive cardiac cycles are random, then the model transfer function is equivalent to the probability density function. The response of the model to a step input is equivalent to the probability di... View full abstract»

    Muscle sounds were recorded from the medial biceps of 37 subjects as they pressed against a stationary object. The recordings were analyzed with a digital computer for frequency content. 20 subjects had some form of neuromuscular disorder, while 17 had no known muscle impairment. View full abstract»

    A method which recognizes the shape of the ST segment is presented in this paper. This method when applied to an ST segment gives as results: 1) the onset and the end of the ST segment and 2) the equation of a straight line or of a parabola that best approximates this ST segment.

  • Analysis of Models for External Stimulation of Axons

    Extracellular electrodes produce electrical fields at the outside of nerve fibers. Discretization of the axon's length coordinate allows simulation of the excitation by a system of differential equations in time, and difference equations in space. For myelinated fibers this segmentation is naturally given by the nodes of Ranvier, whereas unmyelinated axons can be segmented arbitrarily. In both cas... View full abstract»
