Characteristic nonlinearities of the 3/s ictal electroencephalogram identified by nonlinear autoregressive analysisSpringer Science and Business Media LLC - Tập 72 - Trang 519-526 - 1995
Nicholas D. Schiff, Jonathan D. Victor, Annemarie Canel, Douglas R. Labar
We describe a method for the characterization of electroencephalographic (EEG) signals based on a model which features nonlinear feedback. The characteristic EEG ‘fingerprints’ obtained through this approach display the time-course of nonlinear interactions, rather than aspects susceptible to standard spectral analysis. Fingerprints of seizure discharges in six patients (five with typical absence ...... hiện toàn bộ
Predictability of visual perturbation during locomotion: implications for corrective efference copy signalingSpringer Science and Business Media LLC - - 2012
Boris P. Chagnaud, John Simmers, Hans Straka
In guiding adaptive behavior, efference copy signals or corollary discharge are traditionally considered to serve as predictors of self-generated sensory inputs and by interfering with their central processing are able to counter unwanted consequences of an animal’s own actions. Here, in a speculative reflection on this issue, we consider a different functional role for such intrinsic predictive s...... hiện toàn bộ
A theory for the development of feature detecting cells in visual cortexSpringer Science and Business Media LLC - Tập 19 - Trang 1-18 - 1975
Menasche M. Nass, Leon N. Cooper
Passive modification of the strength of synaptic junctions that results in the construction of internal mappings with some of the properties of memory is shown to lead to the development of Hubel-Wiesel type feature detectors in visual cortex. With such synaptic modification a cortical cell can become committed to an arbitrary but repeated external pattern, and thus fire every time the pattern is ...... hiện toàn bộ
Stochastic processes with optimization — A model of learning in higher systemsSpringer Science and Business Media LLC - Tập 50 - Trang 313-327 - 1984
Dan Teodorescu
A special class of stochastic processes with optimization (SPO) is considered and their long-run behaviour is investigated. At each step of the process {X

h is a discrete random variable) a loss function expressing the distance with respect to the moments in the previous step is minimized. The transformation leading from a certain probability dist...... hiện toàn bộ
A planar neuro-musculoskeletal arm model in post-stroke patientsSpringer Science and Business Media LLC - Tập 112 - Trang 483-494 - 2018
Mehran Asghari, Saeed Behzadipour, Ghorban Taghizadeh
Mathematical modeling of the neuro-musculoskeletal system in healthy subjects has been pursued extensively. In post-stroke patients, however, such models are very primitive. Besides improving our general understanding of how stroke affects the limb motions, they can be used to evaluate rehabilitation strategies by computer simulations before clinical evaluations. A planar neuro-musculoskeletal arm...... hiện toàn bộ
On the classification of visual patterns: Systems analysis using detection experimentsSpringer Science and Business Media LLC - Tập 25 - Trang 121-130 - 1977
M. Fansa, W. v. Seelen
Behavioral experiments are indispensable for the analysis of biological systems for cognition and recognition. When these are carried out as detection experiments three types of description can be used for the problem of visual pattern recognition which allow conclusions to be drawn on the operating function of the system. Provided that the signals to be recognized have additive noise superimposed...... hiện toàn bộ
