Makarov, Valeri A. ; Velarde, Manuel G. ; Chetverikov, Alexander ; Ebeling, Werner | American Physical Society | 2006-06We provide here a thorough analysis of the interplay between anharmonic lattice dynamics (with exponential repulsion between units) and electric conduction in a driven-dissipative electrically charged one-dimensional system. First, we delineate [...]texto impreso
Makarov, Valeri A. ; Pavlov, Alexey N. ; Mosekilde, Erik ; Sosnovtseva, Olga V. | Oxford University Press | 2006-12The article makes use of three different examples (sensory information processing in the rat trigeminal complex, intracellular interaction in snail neurons and multimodal dynamics in nephron autoregulation) to demonstrate how modern approaches t[...]texto impreso
In the present work we study how sensory inputs conveyed by nerve fibers in the form of spatiotemporal patterns generate different responses in the central nervous system (CNS) depending on the physical characteristics of the stimulus applied an[...]texto impreso
Makarov, Valeri A. ; Del Río, Ezequiel ; Bedia, Manuel G. ; Velarde, Manuel G. ; Ebeling, Werner | World Academy of Science, Engineering & Technology | 2006We proposed the use of a Toda-Rayleigh ring as a central pattern generator (CPG) for controlling hexapodal robots. We show that the ring composed of six Toda-Rayleigh units coupled to the limb actuators reproduces the most common hexapodal gaits[...]texto impreso
Makarov, Valeri A. ; Nekorkin, Vladimir I. ; Velarde, Manuel G. | American Physical Society | 1998-11We consider a chain with many locally coupled bistable nonisochronous oscillators. We show that on the "background" of a disordered amplitude distribution either phase or frequency clusters form in the chain. Cluster location varies according to[...]texto impreso
We study a one-dimensional ring chain of length L with N particles interacting via Morse potentials and influenced by dissipative forces (passive and active friction). We show that by negative friction the system can be driven far from the therm[...]texto impreso
Makarov, Valeri A. ; Villacorta-Atienza, José Antonio ; Salas, Luis ; Alba, Luis ; Velarde, Manuel G. | Spie-Int Soc Optical Engineering | 2011Animals for surviving have developed cognitive abilities allowing them an abstract representation of the environment. This Internal Representation (IR) could contain a huge amount of information concerning the evolution and interactions of the e[...]texto impreso
Animals for survival in complex, time-evolving environments can estimate in a "single parallel run" the fitness of different alternatives. Understanding of how the brain makes an effective compact internal representation (CIR) of such dynamic si[...]texto impreso
Makarov, Valeri A. ; Castellanos, Nazareth P. ; Malmierca, Eduardo ; Núñez, Ángel | American Physiological Society | 2007Precise and reproducible spike timing is one of the alternatives of the sensory stimulus encoding. We test coherence (repeatability) of the response patterns elicited in projecting gracile neurons by tactile stimulation and its modulation provok[...]texto impreso
Fernández Ruiz, Antonio ; Muñoz, Sagrario ; Sancho, Miguel ; Makarova, Julia ; Makarov, Valeri A. ; Herreros, Oscar | Society for Neuroscience | 2013-09To determine why some pathways but not others produce sizable local field potentials (LFPs) and how far from the source can these be recorded, complementary experimental analyses and realistic modeling of specific brain structures are required. [...]texto impreso
The evolution and collision of dark solitary waves (solitons) appearing in cigar-shaped Bose-Einstein condensates with repulsive atom-atom interaction are here considered using a Boussinesq-Korteweg-de Vries description. We provide theoretical p[...]texto impreso
The spontaneous activity of working neurons yields synaptic currents that mix up in the volume conductor. This activity is picked up by intracerebral recording electrodes as local field potentials (LFPs), but their separation into original infor[...]texto impreso
Makarov, Valeri A. ; Río, E. del ; Ebeling, Werner ; Velarde, Manuel G. | American Physical Society | 2001-09A detailed theoretical and experimental analysis of the possible oscillatory regimes of the dissipative Toda-Rayleigh lattice system is provided. It is shown that the system has (N-1) oscillatory modes with different space-time scales and two ro[...]texto impreso
Martín Vazquez, Gonzalo ; Benito, Nuria ; Makarov, Valeri A. ; Herreras, Oscar ; Makarova, Julia | Oxford University Press | 2016Identifying the pathways contributing to local field potential (LFP) events and oscillations is essential to determine whether synchronous interregional patterns indicate functional connectivity. Here, we studied experimentally and numerically h[...]texto impreso
Makarov, Valeri A. ; Song, Yongli ; Velarde, Manuel G. ; Hübner, David ; Cruse, Holk | Springer Verlag | 2008-05We study how individual memory items are stored assuming that situations given in the environment can be represented in the form of synaptic-like couplings in recurrent neural networks. Previous numerical investigations have shown that specific [...]texto impreso
Makarov, Valeri A. ; Río, E. del ; Ebeling, Werner ; Velarde, Manuel G. | Spie-Int Soc Optical Engineering | 2003An experimental study has been carried out of a noisy dissipative-driven ring lattice of units coupled via Morse potentials. An electronic circuit mimicking the lattice dynamics and noise sources is used. We show that inclusion of long range att[...]texto impreso
Makarova J, Makarova VA, Herreras O. Generation of sustained field potentials by gradients of polarization within single neurons: a macroscopic model of spreading depression. J Neurophysiol 103: 2446-2457, 2010. First published March 10, 2010; d[...]texto impreso
High-dimensional data and high-dimensional representations of reality are inherent features of modern Artificial Intelligence systems and applications of machine learning. The well-known phenomenon of the “curse of dimensionality” states: many p[...]texto impreso
Surface electromyographic (sEMG) signals represent a superposition of the motor unit action potentials that can be recorded by electrodes placed on the skin. Here we explore the use of an easy wearable sEMG bracelet for a remote interaction with[...]texto impreso
Makarov, Valeri A. ; Castellanos, Nazareth P. | World Academy of Science, Engineering & Technology | 2006Statistical analysis of electrophysiological recordings obtained under, e.g. tactile, stimulation frequently suggests participation in the network dynamics of experimentally unobserved "hidden" neurons. Such interneurons making synapses to exper[...]texto impreso
Lobov, Sergey ; Krilova, Nadia ; Kastalskiy, Innokentiy ; Kazantsev, Victor ; Makarov, Valeri A. | MDPI | 2018-04-06Recent advances in recording and real-time analysis of surface electromyographic signals (sEMG) have fostered the use of sEMG human–machine interfaces for controlling personal computers, prostheses of upper limbs, and exoskeletons among others.

The synchronization of oscillatory activity in networks of networks is usually implemented through coupling the state variables describing the dynamics of each network. Here we study another but complementary mechanism of synchronization in unid[...]texto impreso
Villacorta-Atienza, José Antonio ; Calvo, Carlos ; Lobov, S. ; Makarov, Valeri A. | EDP SCIENCES S A | 2017The fundamental bases of how our brain solves different tasks of object manipulation remain largely unknown. Here we consider the problem of the limb movement in dynamic situations on an abstract cognitive level and propose a novel approach rely[...]texto impreso
Makarov, Valeri A. ; Berg, Christian ; Villacorta-Atienza, José Antonio ; Velarde, Manuel G. ; Arena, Paolo ; Patane, Luca ; Termini, Pietro Savio ; Strauss, Roland | Informa Healthcare | 2010-12Proper orientation is one of the most important skills in the repertoire of an organism. Many different strategies are used in the animal kingdom to find resources like food, nesting sites, a comfortable environment, or mating partners. Optimizi[...]texto impreso
In the present paper we propose a novel method for the identification and modeling of neural networks using extracellular spike recordings. We create a deterministic model of the effective network, whose dynamic behavior fits experimental data. [...]
