A theoretical model of phase transitions in the human brain
Springer Science and Business Media LLC - Tập 71 - Trang 27-35 - 1994
An experiment using a multisensor SQUID (superconducting quantum interference device) array was performed by Kelso and colleagues (1992) which combined information from three different sources: perception, motor response, and brain signals. When an acoustic stimulus frequency is changed systematically, a spontaneous transition in coordination occurs at a critical frequency in both motor behavior a...... hiện toàn bộ
Cooperation in self-organizing map networks enhances information transmission in the presence of input background activity

Reconstruction of the input signal of the leaky integrate-and-fire neuronal model from its interspike intervals
Springer Science and Business Media LLC - Tập 110 - Trang 3-15 - 2015
Extracting the input signal of a neuron by analyzing its spike output is an important step toward understanding how external information is coded into discrete events of action potentials and how this information is exchanged between different neurons in the nervous system. Most of the existing methods analyze this decoding problem in a stochastic framework and use probabilistic metrics such as ma...... hiện toàn bộ
Pulse sequences generated by a degenerate analog neuron model
Springer Science and Business Media LLC - Tập 45 - Trang 23-33 - 1982
The response characteristics of an electronic neuron model proposed by the authors are investigated. Periodic stimulating pulse sequences with a fixed frequency are applied to the analog neuron model and the response pulse sequences are studied. In the degenerate case, the state transition of the neuron model during one period of the stimulating pulse sequence is described by a first order piecewi...... hiện toàn bộ
The value of asymmetric signal processing in klinokinesis
Springer Science and Business Media LLC - Tập 61 - Trang 401-404 - 1989
Klinokinesis is a behavioral mechanism in which an organism moves toward or away from a stimulus source by altering its frequency of change of direction without biasing its turns with respect to the stimulus field. Previous studies of a variety of organisms have demonstrated that rates of adaptation (or other information processing features) for increases and decreases in stimulus intensity are of...... hiện toàn bộ
Identification of nonlinear systems using random impulse train inputs
Springer Science and Business Media LLC - Tập 19 - Trang 217-230 - 1975
Nonlinear systems that require discrete inputs can be characterized by using random impulse train (Poisson process) inputs. The method is analagous to the Wiener method for continuous input systems, where Gaussian white-noise is the input. In place of the Wiener functional expansion for the output of a continuous input system, a new series for discrete input systems is created by making certain re...... hiện toàn bộ
On the choice of noise for the analysis of the peripheral auditory system
Springer Science and Business Media LLC - Tập 29 - Trang 97-104 - 1978
The cross-correlation between output and input of a system containing nonlinearities, when that system is stimulated with Gaussian white noise, is a good estimate of the linear properties of the system. In practice, however, when sequences of pseudonoise are used, great errors may be introduced in the estimate of the linear part depending on the properties of the noise. This consideration assumes ...... hiện toàn bộ

Important relation between EEG and brain evoked potentials
Springer Science and Business Media LLC - Tập 25 - Trang 41-48 - 1976
In this study, the amplitude frequency characteristics, which are obtained by application of Fourier transform to the selectively averaged evoked potentials (SAEPs) recorded from human vertex and occipital scalp electrodes upon acoustical step stimulation, are given and discussed. The resonance phenomena which we have observed in the cat brain are also demonstrated in humans by comparing the compo...... hiện toàn bộ
Neural models of brightness perception and retinal rivalry in binocular vision
Springer Science and Business Media LLC - Tập 43 - Trang 13-21 - 1982
In binocular fusion, pairs of left and right stimuli yielding the same brightness perception constitute an equibrightness curve in a coordinate system whose ordinate and abscissa correspond to the left and right stimulus strengths. A neural network model is presented to elucidate the characteristics of the curve. According to the model, Fechner's paradox is due to the threshold characteristics of ...... hiện toàn bộ
