Central fatigue induced by short-lasting finger tapping and isometric tasks: a study of silent periods evoked at spinal and supraspinal levels
(Elsevier, 2015-08-01)[Abstract] The neural substrates of fatigue induced by muscular activity have been addressed in depth in relation to isometric tasks. For these activities, when fatigue develops, it has been noted that the duration of the ... -
Changes in EMG activity during clenching in chronic pain patients with unilateral temporomandibular disorders
(Elsevier, 2008-10-08)[Abstract] The study assessed the differences in electromyographic (EMG) activity recorded during clenching in women with chronic unilateral temporomandibular disorders (TMDs) as compared to control subjects. Seventy-five ... -
Changes in Visual Responses in the Feline dLGN: Selective Thalamic Suppression Induced by Transcranial Magnetic Stimulation of V1
(Oxford University Press, 2006-08-14)[Abstract] Transcranial magnetic stimulation (TMS) of the cortex can modify activity noninvasively and produce either excitatory or inhibitory effects, depending on stimulus parameters. Here we demonstrate controlled ... -
Chronic neural adaptation induced by long-term resistance training in humans
(Springer, 2006-02-28)[Abstract] While it is known that resistance training causes changes in the central nervous system (CNS) in the initial stages of training, there have been few studies of cumulative or sustained neural adaptation to ... -
Combinación de nuevas técnicas electrofisiológicas y de imagen en el estudio de la función de la corteza visual primaria
(J. V. Sácnhez Andrés, 2003)This work summarizes current research focused on explaining orientation selectivity of primary visual cortex (V1), and describes the electrophysiological and imaging techniques than are being used. Development. The study ... -
Completing the corticofugal loop: a visual role for the corticogeniculate Type 1 metabotropic glutamate receptor
(Society of Neuroscience, 2002-04-01)[Abstract] The way in which the brain deals with sensory information relies not only on feedforward processing of signals from the periph- ery but also on feedback inputs. This is the case of the massive projection back ... -
Controlled trial on the effect of 10 days low-frequency repetitive transcranial magnetic stimulation (rTMS) on motor signs in Parkinson´s disease
(Wiley, 2010-07-28)[Abstract] We evaluated the effect of low-frequency rTMS on motor signs in Parkinson’s disease (PD), under a doubleblind placebo-controlled trial design. PD patients were randomly assigned to received either real (n 5 ... -
La corteza cerebral modula la transmisión cutánea a través de los núcleos de los cordones posteriores
(J.V. Sánchez Andrés, 2001)The mechanisms used by the cerebral cortex to modulate the cutaneous information at prethalamic level have been scarcely studied. This article reviews experimental evidence leading to a better understanding of this issue ... -
Cortical modulation of dorsal column nuclei: a computational study
(Springer, 2006-04-22)[Abstract] We present a computational study aimed at exploring the sensorimotor cortex modulation of the behaviour of dorsal column nuclei, specifically the impact of synaptic parameters, during both sleep and waking ... -
Cortical Modulation of the Transient Visual Response at Thalamic Level: A TMS Study
(PLoS ONE, 2011-02-10)[Abstract] The transient visual response of feline dorsal lateral geniculate nucleus (dLGN) cells was studied under control conditions and during the application of repetitive transcranial magnetic stimulation at 1 Hz ... -
Cortico-subcortical synchronization in the chloralose-anesthetized cat
(Elsevier, 1999-07)[Abstract] The spontaneous and paroxysmal cerebral cortical synchronized activity was used as reference to study the cortical impact exerted on subcortical neurons. The sensorimotor cortical synchronized activity spread ... -
Coupled slow and delta oscillations between cuneothalamic and thalamocortical neurons in the chloralose anesthetized cat
(Elsevier, 1996)Simultaneous recordings were obtained from cuneothalamic (extracellular) and thalamocortical (intracellular) cells in chloralose anesthetized cats. It was found that cuneothalamic neurons present slow rhythmicity (0.1–1 ... -
Coupled slow and delta oscillations between cuneothalamic and thalamocortical neurons in the chloralose anesthetized cat
(Elsevier, 1996)[Abstract] Simultaneous recordings were obtained from cuneothalamic (extracellular) and thalamocortical (intracellular) cells in chloralose anesthetized cats. It was found that cuneothalamic neurons present slow rhythmicity ... -
Cross nearest-spike interval based method to measure synchrony dynamics
(American Institute of Mathematical Sciences, 2014-02)[Abstract] A new synchrony index for neural activity is de ned in this paper. The method is able to measure synchrony dynamics in low ring rate scenarios. It is based on the computation of the time intervals between ... -
Cross‑modal reaction of auditory and visual cortices after long‑term bilateral hearing deprivation in the rat
(Springer Nature, 2019-11-28)[Abstract] Visual cortex (VC) over-activation analysed by evoked responses has been demonstrated in congenital deafness and after longterm acquired hearing loss in humans. However, permanent hearing deprivation has not ... -
Depressive symptoms and their severity in a sample with lymphedema: a case-control investigation
(Frontiers, 2023-07-05)[Abstract] Objectives: Depression is a condition that can be associated with other illnesses, especially chronic illnesses. Lower limb lymphedema is a chronic, disabling condition that can affect the quality of life and ... -
Different sources of nitric oxide mediate neurovascular coupling in the lateral geniculate nucleus of the cat
(Frontiers, 2009-09-08)[Abstract] Understanding the link between neuronal responses (NRs) and metabolic signals is fundamental to our knowledge of brain function and it is a milestone in our efforts to interpret data from modern non invasive ... -
Differential feedback modulation of center and surround mechanisms in parvocellular cells in the visual thalamus
(Society of Neuroscience, 2012-11-07)[Abstract] Many cells in both the central visual system and other sensory systems exhibit a center surround organization in their receptive field, where the response to a centrally placed stimulus is modified when a ... -
Differential responses of spinal motoneurons to fatigue induced by short-lasting repetitive and isometric tasks
(Elsevier, 2016-10-24)[Abstract] Compared to isometric activities, the neural basis of fatigue induced by repetitive tasks has been scarcely studied. Recently, we showed that during short-lasting repetitive tasks at the maximal possible rate ... -
