Arias, Pablo; Espinosa, Nelson; Robles-García, Verónica; Cao, Ricardo; Cudeiro, Javier (Elsevier, 2012-03-21)[Abstract] Increased antagonist muscle co-activation of the lower limb during walking seems to be an adaptive process to the physiological changes of aging, in order to gain joint stability.

Bootstrap testing for cross-correlation under low firing activity
González Montoro, Aldana María; Cao, Ricardo; Espinosa, Nelson; Cudeiro, Javier; Mariño Alfonso, Xurxo (Springer, 2015-04-14)[Abstract] A new cross-correlation synchrony index for neural activity is proposed. The index is based on the integration of the kernel estimation of the cross-correlation function. It is used to test for the dynamic ... -
Bursting thalamic responses in awake monkey contribute to visual detection and are modulated by corticofugal feedback
Ortuño Silva, Tania; Grieve, Kenneth; Cao, Ricardo; Cudeiro, Javier; Rivadulla, Casto (Frontiers, 2014-05-30)[Abstract] The lateral geniculate nucleus is the gateway for visual information en route to the visual cortex. Neural activity is characterized by the existence of two firing modes: burst and tonic. Originally associated ... -

Marakova, Julia; Ortuño Silva, Tania; Korovaichuk, Alejandra; Cudeiro, Javier; Marakov, Valeri A.; Rivadulla, Casto; Herreras, Oscar (Frontiers, 2014-05-01)[Abstract] Deciphering how the brain encodes the continuous flow of information contained in natural stimuli requires understanding the spontaneous activity of functional assemblies in multiple neuronal populations. A ... -
Central fatigue induced by short-lasting finger tapping and isometric tasks: a study of silent periods evoked at spinal and supraspinal levels
Arias, Pablo; Robles-García, Verónica; Corral Bergantiños, Yoanna; Madrid, Andy; Espinosa, Nelson; Valls-Solé, Josep; Grieve, Kenneth; Oliviero, Antonio; Cudeiro, Javier (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 ... -
Controlled trial on the effect of 10 days low-frequency repetitive transcranial magnetic stimulation (rTMS) on motor signs in Parkinson´s disease
Arias, Pablo; Vivas-Costa, Jamile; Grieve, Kenneth; Cudeiro, Javier (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 ... -

Espinosa, Nelson; Mariño Alfonso, Xurxo; Labra, Carmen de; Cudeiro, Javier (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 ... -
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 ... -
