Completing the corticofugal loop: a visual role for the corticogeniculate Type 1 metabotropic glutamate receptor
Rivadulla, Casto; Martínez Otero, Luis Miguel; Varela, Carmen; Cudeiro, Javier (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 ... -

Cross‑modal reaction of auditory and visual cortices after long‑term bilateral hearing deprivation in the rat
Pernia, M.; Díaz, I.; Colmenárez‑Raga, A. C.; Rivadulla, Casto; Cudeiro, Javier; Plaza, I.; Merchán, M. A. (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 ... -

Labra, Carmen de; Rivadulla, Casto; Espinosa, Nelson; Dasilva, Miguel; Cao, Ricardo; Cudeiro, Javier (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
Jones, Helen E.; Andolina, Ian M.; Ahmed, Bashir; Shipp, Stewart D.; Clements, Jake T.; Grieve, Kenneth; Cudeiro, Javier; Salt, Thomas E.; Sillito, Adam M. (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
Madrid, Antonio; Valls-Solé, Josep; Oliviero, Antonio; Cudeiro, Javier; Arias, Pablo (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 ... -
Does the Pulvinar-Lp Complex Contribute to Motor Programming?
Cudeiro, Javier; González, F.; Pérez, R.; Alonso, J.M.; Acuña, Carlos (Elsevier, 1989)[Abstract] Extracellular unit recording studies in the pulvinar lateral posterior complex (Pui-LP) of behaving monkeys have shown a response property not previously reported. In monkeys performing aimed arm reaching movements ... -
Double-blind, randomized, placebo controlled trial on the effect of 10 days low-frequency rTMS over the vertex on sleep in Parkinson’s disease
Arias, Pablo; Vivas-Costa, Jamile; Grieve, Kenneth; Cudeiro, Javier (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 rhythmic auditory stimulation on gait in Parkinsonian patients with and without freezing of gait
Arias, Pablo; Cudeiro, Javier (PLoS ONE, 2010-03-22)[Abstract] Freezing of gait (FOG) in Parkinson’s disease (PD) rises in prevalence when the effect of medications decays. It is known that auditory rhythmic stimulation improves gait in patients without FOG (PD-FOG), but ... -
Effect of Stimulation Timing on Testing Voluntary Muscle Force Generation
Madrid López, Antonio; Madinabeitia-Mancebo, Elena; Robles-García, Verónica; Chouza-Insua, Marcelo; Cudeiro, Javier; Arias, Pablo (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
Madrid, Antonio; Madinabeitia-Mancebo, Elena; Cudeiro, Javier; Arias, Pablo (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 ... -
