Invariant computations in local cortical networks with balanced excitation and inhibition
(Nature, 2005-06-23)[Abstract] Cortical computations critically involve local neuronal circuits. The computations are often invariant across a cortical area yet are carried out by networks that can vary widely within an area according to its ... -
Kinesiophobia Levels in Patients with Parkinson’s Disease: A Case-Control Investigation
(MDPI, 2021-04-30)[Abstract] Background: Kinesiophobia can be an obstacle to physical and motor activity in patients with Parkinson’s disease (PD). PD affects patients’ independence in carrying out daily activities. It also impacts a ... -
Lemniscal recurrent and transcortical influences on cuneate neurons
(Elsevier, 2000)[Abstract] Intracellular recordings were obtained from cuneate neurons of chloralose-anesthetized, paralysed cats to study the synaptic responses induced by electrical stimulation of the contralateral medial lemniscus. ... -
Local networks in visual cortex and their influence on neuronal responses and dynamics
(Elsevier, 2005-11-07)[Abstract] Networks of neurons in the cerebral cortex generate complex outputs that are not simply predicted by their inputs. These emergent responses underlie the function of the cortex. Understanding how cortical networks ... -
Looking back: corticothalamic feedback and early visual processing
(Elsevier, 2006)[Abstract] Although once regarded as a simple sensory relay on the way to the cortex, it is increasingly apparent that the thalamus has a role in the ongoing moment-by-moment processing of sensory input and in cognition. ... -
Low-cost virtual reality system in evaluation of rhythmic motor patterns in elderly and Parkinsonian patients
(MIT Press, 2014-04-30)[Abstract] This work details a Virtual Reality (VR) system developed to evaluate and potentially treat alterations in hand movements and central rhythm formation in Parkinsonian and Elderly subjects. An essential feature ... -
M1 inhibition dependency on slowing of muscle relaxation after brief and fast fatiguing repetitive movements: preliminary results
(Springer, 2018-10-16)[Abstract] This work presents preliminary results on the association between central and peripheral expressions of muscle fatigue induced by unresisted repetitive movements. We tested cortico-spinal excitability and ... -
Magnetic field strength and reproducibility of neodymium magnets useful for transcranial static magnetic field stimulation of the human cortex
(Wiley, 2013-10-11)[Abstract] Objective. The application of transcranial static magnetic field stimulation (tSMS) in humans reduces the excitability of the motor cortex for a few minutes after the end of stimulation. However, when tSMS is ... -
Mixed burst and tonic firing in the thalamus: a study in the feline lateral geniculate nucleus in vivo
(Elsevier, 2009)[Abstract] Compounds known to inhibit or disfacilitate cells in cat dorsal lateral geniculate nucleus (dLGN) were applied iontophoretically in vivo. Application of GABA, or agonists of GABAA and GABAB receptors, markedly ... -
Modelling the circuitry of the cuneate nucleus
(Springer, 1999)Experimental data recorded in cat "in vivo" offer a new picture of the cuneate nucleus. Clasically definied as a simple relay station, the cuneate nucleus is currently seen as a fundamental stage in somatosensory information ... -
Modulatory effects mediated by metabotropic glutamate receptor 5 on lateral geniculate nucleus relay cells
(Wiley, 2005-01-18)[Abstract] Glutamate is thought to be the excitatory neurotransmitter in the lateral geniculate nucleus (LGN) of the cat, mediating visual transmission from the retina via ionotropic receptors of both d,l-α-amino-3-hydro ... -
Motor facilitation during real-time movement imitation in Parkinson’s disease: a virtual reality study
(Elsevier, 2013-08-06)[Abstract] Background: Impaired temporal stability and poor motor unit recruitment are key impairments in Parkinsonian motor control during a whole spectrum of rhythmic movements, from simple finger tapping to gait. Therapies ... -

La musicoterapia durante procedimientos en los pacientes quemados
(Proyecto Lumbre, 2020-12)[Resumen] Introducción: en este artículo, se resume una de las pocas revisiones sistemáticas con metaanálisis publicadas sobre los efectos de la musicoterapia en los pacientes quemados. Material y métodos: en la revisión, ... -
New tools for old problems: magnetic stimulation to study (and help) the brain
(Springer Nature, 2017)[Abstract] Magnetic stimulation techniques, either repetitive TMS (rTMS) or Static Magnetic Fields, allow to modulate brain activity through the skull in a non invasive and painless way. When rTMS is used, low frequencies ... -
Nitric oxide-mediated cortical activation: a diffuse wake-up system
(Society of Neuroscience, 2003)Nitric oxide (NO) has been implicated in some of the central pathways engaged in the regulation of the sleep–wake cycle. The existence of nitric oxide synthase (NOS) in the cholinergic basal forebrain (BF) cells projecting ... -
Parenting profiles: motivation toward health-oriented physical activity and intention to be physically active
(Springer Nature, 2023-07-12)[Abstract] Introduction: Parents influence their sons' and daughters' interest in practicing and maintaining physical activity through parenting patterns. Objective: To identify perceived parenting style profiles and ... -
Perceived physical self-concept profiles: intention to be physically active and emotional regulation
(Fundación Veca, 2023)[Abstract] The objectives of the study were to identify physical self-concept profiles and examine their role in the intention to be physically active and emotional regulation. A sample of 606 physical activity practitioners ... -
Peripheral-Central Interplay for Fatiguing Unresisted Repetitive Movements: A Study Using Muscle Ischaemia and m1 Neuromodulation
(Nature Research, 2021-01-22)[Abstract] Maximal-rate rhythmic repetitive movements cannot be sustained for very long, even if unresisted. Peripheral and central mechanisms of fatigue, such as the slowing of muscle relaxation and an increase in M1-GABAb ... -
Prevalence of Fatigue and Associated Factors in a Spinal Cord Injury Population: Data from an Internet-Based and Face-to-Face Surveys
(Mary Ann Liebert, 2017-08-01)[Abstract] Fatigue has a profound impact on patients with spinal cord injury (SCI), but only limited treatments are available. The aim of this study was to determine the prevalence of fatigue in SCI and its association ...
