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 ... -
Double-blind, randomized, placebo controlled trial on the effect of 10 days low-frequency rTMS over the vertex on sleep in Parkinson’s disease
(Elsevier, 2010-07-31)[Abstract] Objective: A recent report indicates repetitive transcranial magnetic stimulation (rTMS) improves sleep in Parkinson’s disease (PD). The aim of this work is to evaluate the effect of 10 days rTMS on sleep ... -
Effect of Stimulation Timing on Testing Voluntary Muscle Force Generation
(Elsevier, 2020-10-08)[Abstract] Background. The interpolated twitch technique (ITT) is a ubiquitous test for assessing the level of voluntary muscle force generation, in which muscle twitches are evoked via percutaneous electrical stimulation. ... -
Effects of a finger tapping fatiguing task on M1-intracortical inhibition and central drive to the muscle
(Nature, 2018)[Abstract] The central drive to the muscle reduces when muscle force wanes during sustained MVC, and this is generally considered the neurophysiological footprint of central fatigue. The question is if force loss and the ... -
Effects of early or late-evening fatiguing physical activity on sleep quality in non-professional sportsmen
(Edizioni Minerva Médica, 2016-05-01)[Abstract] Background: This study aims to understand whether night sleep-quality is distorted by fatiguing physical activity (PA) when conducted early or late in the evening. Methods: Nine males (18-38yrs) performed ... -
Effects of Fatigue Induced by Repetitive Movements and Isometric Tasks on Reaction Time
(Elsevier, 2020-09-25)[Abstract] Purpose: The understanding of fatigue of the human motor system is important in the fields of ergonomics, sport, rehabilitation and neurology. In order to understand the interactions between fatigue and reaction ... -
Effects of movement imitation training in Parkinson's disease: a virtual reality pilot study
(Elsevier, 2016-05)[Abstract] Background. Hypometria is a clinical motor sign in Parkinson's disease. Its origin likely emerges from basal ganglia dysfunction, leading to an impaired control of inhibitory intracortical motor circuits. Some ... -
Effects of static magnetic fields on the visual cortex: reversible visual deficits and reduction of neuronal activity
(Oxford, 2014-09-26)[Abstract] Noninvasive brain stimulation techniques have been successfully used to modulate brain activity, have become a highly useful tool in basic and clinical research and, recently, have attracted increased attention ... -
Efficacy of Bracing on Thoracic Kyphotic Angle and Functionality in Women with Osteoporosis: A Systematic Review
(MDPI, 2022-05-24)[Abstract] Background and purpose: Osteoporotic hyperkyphosis is associated with adverse outcomes, such as fatigue, back pain, or reduced back extensor strength, with a negative impact on functionality and quality of life. ... -
Endocannabinoid CB1 receptors modulate visual output from the thalamus
(Springer, 2011-07-20)[Abstract] Rationale Endocannabinoids have emerged as a modulatory brain system affecting different types of synapses, broadly distributed throughout the CNS, which explain the diverse psychophysical effects observed ... -
Factors related to greater functional recovery after suffering a stroke
(MDPI, 2021-06-17)[Abstract] Background: In a stroke, the importance of initial functional status is fundamental for prognosis. The aim of the current study was to investigate functional status, assessed by the Functional Independence ... -
Figure-ground modulation in awake primate thalamus
(National Academy of Sciences, 2015)[Abstract] Figure-ground discrimination refers to the perception of an object, the figure, against a nondescript background. Neural mechanisms of figure-ground detection have been associated with feedback interactions ... -
Hyperthermia-Induced Changes in EEG of Anesthetized Mice Subjected to Passive Heat Exposure
(Frontiers, 2021-09-09)[Abstract] Currently, the role of hypothermia in electroencephalography (EEG) is well-established. However, few studies have investigated the effect of hyperthermia on EEG, an important physiological parameter governing ... -
Influence of parental involvement and parenting styles in children's active lifestyle: a systematic review
(Peer J, 2023-12-21)[Abstract] Background: Parents influence their children's lifestyles through modeling and support, which modifies how children approach physical activity. As such, this systematic review aims to know the influence of ... -
Intraneural IFG-1 in cryopreserved nerve isografts increase neural regeneration and functional recovery in the rat sciatic nerve
(Oxford, 2018-07-27)[Abstract] Background: Insulin-like growth factor 1 (IGF-1) was found to stimulate Schwann cell mitosis. Exogenous IGF-1 may improve nerve regeneration after cryopreservation. Objective: To evaulate the effect of ... -
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 ... -
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 ... -
