Responses of primate LGN cells to moving stimuli involve a constant background modulation by feedback from area MT
(Elsevier, 2013-05-03)[Abstract] The feedback connections from the cortical middle temporal (MT) motion area, to layer 6 of the primary visual cortex (V1), have the capacity to drive a cascaded feedback influence from the layer 6 cortico-geniculate ... -
Spatiotemporal gait patterns during overt and covert evaluation in patients with Parkinson’s disease and healthy subjects: is there a hawthorne effect?
(Human Kinetics, 2015)[Abstract] Parkinson's disease (PD) and aging lead to gait impairments. Some of the disturbances of gait are focused on step length, cadence, and temporal variability of gait cycle. Under experimental conditions gait can ... -
Spectroscopic measurement of cortical nitric oxide release induced by ascending activation
(Elsevier, 2014-11-25)[Abstract] The transition from sleep to the awake state is regulated by the activation of subcortical nuclei of the brainstem (BS) and basal forebrain (BF), releasing acetylcholine and glutamate throughout the cortex and ... -
Static magnetic fields reduce epileptiform activity in anesthetized rat and monkey
(Nature, 2018-10-30)[Abstract] Increasing evidence indicates that static magnetic fields (SMF) reduce cortical activity in both human and animal models. The aim of this work was to investigate the effect of SMF on epileptiform cortical activity, ... -
Suppression of V1 feedback produces a shift in the topographic representation of receptive fields of LGN cells by unmasking latent retinal drives
(Oxford, 2017-03-18)[Abstract] In awake monkeys, we used repetitive transcranial magnetic stimulation (rTMS) to focally inactivate visual cortex while measuring the responsiveness of parvocellular lateral geniculate nucleus (LGN) neurons. ... -
Temporal Dynamics of Muscle, Spinal and Cortical Excitability and Their Association With Kinematics During Three Minutes of Maximal-Rate Finger Tapping
(Springer Nature, 2020-02-21)[Abstract] We tested peripheral, spinal and cortical excitability during 3 minutes of unresisted finger tapping at the maximal possible rate, which induced fatigue. Subsequently, we studied the temporal dynamics of muscle ... -
The effects of expectancy on corticospinal excitability: passively preparing to observe a movement
(American Physiological Society, 2014-01-08)[Abstract] The corticospinal tract excitability is modulated when preparing movements. Earlier to movement execution, the excitability of the spinal cord increases waiting for supraspinal commands to release the movement. ... -
The effects of waveform and current direction on the efficacy and test–retest reliability of transcranial magnetic stimulation
(Elsevier, 2018-10-06)[Abstract] The pulse waveform and current direction of transcranial magnetic stimulation (TMS) influence its interactions with the neural substrate; however, their role in the efficacy and reliability of single- and ... -
The implications of diabetic foot health-related with quality of life: A retrospective case control investigation
(Elsevier, 2022-07-14)[Abstract] The diabetes people show a significant presence of foot health problems are usually all over the world, causing in big economic effects for these persons, their families and world population OBJECTIVE: The purpose ... -
Transcranial Magnetic Stimulation for the Treatment of Cocaine Addiction: A Systematic Review
(MDPI, 2021-11-28)[Abstract] Long-term cocaine use is associated with cognitive deficits and neuro-psychiatric pathologies. Repetitive transcranial magnetic stimulation (rTMS) is an emerging therapeutic strategy relating to changes in brain ... -
Ultrasonographic features of the intrinsic foot muscles in patients with and without plantar fasciitis: a novel case-control research study
(Termedia & Banach, 2021-11-21)[Abstract] Introduction: The aim of the present study was to compare by ultrasound imaging (USI) the thickness and cross-sectional area (CSA) of the flexor hallucis brevis (FHB), flexor digitorum brevis (FDB), abductor ... -
Validity of the finger tapping test in Parkinson’s disease, elderly and young healthy subjects: is there a role for central fatigue?
(Elsevier, 2012-05-03)[Abstract] Objective: The main goal of this work is to evaluate the validity of the finger tapping test (FT) to detect alterations in rhythm formation. Methods: We use FT to study the alterations in motor rhythm in three ... -
Vasomotion and Neurovascular Coupling in the Visual Thalamus In Vivo
(PLoS ONE, 2011-12-09)[Abstract] Spontaneous contraction and relaxation of arteries (and in some instances venules) has been termed vasomotion and has been observed in an extensive variety of tissues and species. However, its functions and ...
