La rehabilitación en las quemaduras pediátricas
(Proyecto Lumbre, 2015-02) -
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 ... -
Sensorimotor cortical influences on cuneate nucleus rhythmic activity in the anesthetized cat
(Elsevier, 1999)[Abstract] This work aimed to study whether the sensorimotor cerebral cortex spreads down its rhythmic patterns of activity to the dorsal column nuclei. Extracellular and intracellular recordings were obtained from the ... -
Sight and insight – on the physiological role of nitric oxide in the visual system
(Elsevier, 1999-03-01)[Abstract] Research in the fields of cellular communication and signal transduction in the brain has moved very rapidly in recent years. Nitric oxide (NO) is one of the latest discoveries in the arena of messenger molecules. ... -
Una simple huella
(Universitat de València, 2019)[Resumen] Transmitir información de una mente a otra no es solo útil, es vital (la palabra vital tiene aquí un profundo sentido en todas sus acepciones). Los animales, desde una tierna y minúscula garrapata hasta las ... -
Sleep and wakefulness in the cuneate nucleus: a computational study
(Springer, 2003)We present a computational study about the influence of the sensorimotor cortex on the processing of the cuneate nucleus during sleep as well as wakefulness. Realistic computational models were developed supported by ... -
Sobre incertidumbres, relojes y perros
(Universitat de València, 2020)[Resumen] «En Italia, en treinta años bajo los Borgia, tuvieron guerras, terror y matanzas, pero produjeron a Miguel Ángel, Leonardo da Vinci y el Renacimiento. En Suiza tuvieron amor fraternal, quinientos años de ... -
Los sorprendentes orígenes de la alegría y de la tristeza
(Universitat de València, 2023-03)[Resumen] Son dos de las emociones básicas, que además suelen imaginarse como complementarias, como en las máscaras del teatro griego clásico, una alegre y sonriente –la comedia– y otra triste –la tragedia–. Pero no se ... -
Spatial frequency tuning of orientation-discontinuity-sensitive corticofugal feedback to the cat lateral geniculate nucleus
(Wiley, 1996-01-15)[Abstract] 1. The influence of spatial frequency on the inhibitory component of the effects mediated by feedback from the visual cortex has been examined in X and Y cells in the A laminae of the feline dorsal lateral ... -
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 ... -
Specific roles of NMDA and AMPA receptors in direction-selective and spatial phase-selective responses in visual cortex
(Society of Neuroscience, 2001)[Abstract] Cells in the superficial layers of primary visual cortex (area 17) are distinguished by feedforward input from thalamic-recipient layers and by massive recurrent excitatory connections be- tween ... -
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 ... -
State-dependent geometry of population activity in rat auditory cortex
(eLife Sciences, 2019-04-10)[Abstract] The accuracy of the neural code depends on the relative embedding of signal and noise in the activity of neural populations. Despite a wealth of theoretical work on population codes, there are few empirical ... -
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. ... -
Synaptic Integration by V1 Neurons Depends on Location Within the Orientation Map
(Elsevier/Cell Press, 2002)[Abstract] Neurons in the primary visual cortex (V1) are organized into an orientation map consisting of orientation domains arranged radially around “pinwheel centers” at which the representations of all orientations ... -
Synergistic effects of applying static magnetic fields and diazepam to improve EEG abnormalities in the pilocarpine epilepsy rat model
(Nature, 2023-01-05)[Abstract] The lithium-pilocarpine rat model is a well-known model of temporal epilepsy. Recently we found that transcranial static magnetic stimulation (tSMS) delay and reduce the signs of EEG in this model. We aim to ... -
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 ... -
Temporal variability of gait in Parkinson disease: effectsof a rehabilitation programme based on rhythmic sound cuesTemporal variability of gait in Parkinson disease: effectsof a rehabilitation programme based on rhythmic sound cues
(Elsevier, 2004)[Abstract] It has been suggested that sequential movements in patients with Parkinson's disease (PD) might be improved by the effects of external rhythmic cues. We studied spatiotemporal gait parameters and temporal gait ... -
The cold-sensing ion channel TRPM8 regulates central and peripheral clockwork and the circadian oscillations of body temperature
(Wiley, 2022-10-17)[Abstract] Aim: Physiological functions in mammals show circadian oscillations, synchronized by daily cycles of light and temperature. Central and peripheral clocks participate in this regulation. Since the ion channel ...
