Dasilva, Miguel A.; Grieve, Kenneth; Cudeiro, Javier; Rivadulla, Casto (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 ... -

Figure-ground modulation in awake primate thalamus
Jones, Helen E.; Andolina, Ian M.; Shipp, Stewart D.; Adams, Daniel L.; Cudeiro, Javier; Salt, Thomas E.; Sillito, Adam M. (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 ... -
Functional two-way analysis of variance and bootstrap methods for neural synchrony analysis
González Montoro, Aldana María; Cao, Ricardo; Espinosa, Nelson; Cudeiro, Javier; Mariño Alfonso, Xurxo (BioMed Central, 2014-08-12)[Abstract] Background: Pairwise association between neurons is a key feature in understanding neural coding. Statistical neuroscience provides tools to estimate and assess these associations. In the mammalian brain, ... -
Further observations on the role of nitric oxide in the feline lateral geniculate nucleus
Cudeiro, Javier; Rivadulla, Casto; Rodríguez, R.; Martínez-Conde, Susana; Martínez, L.; Grieve, Kenneth; Acuña, Carlos (Wiley, 1996-01)[Abstract] We have examined the responses of a population of 77 cells in the dorsal lateral geniculate nucleus (dLGN) of the anaesthetized, paralysed cat. Here the synthetic enzyme for the production of nitric oxide, nitric ... -
Hyperthermia-Induced Changes in EEG of Anesthetized Mice Subjected to Passive Heat Exposure
Labra, Carmen de; Pardo-Vázquez, José L.; Cudeiro, Javier; Rivadulla, Casto (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 ... -
Looking back: corticothalamic feedback and early visual processing
Cudeiro, Javier; Sillito, Adam M. (Elsevier, 2006)[Abstract] Although once regarded as a simple sensory relay on the way to the cortex, it is increasingly apparent that the thalamus has a role in the ongoing moment-by-moment processing of sensory input and in cognition. ... -
Low-cost virtual reality system in evaluation of rhythmic motor patterns in elderly and Parkinsonian patients
Sanmartín, Gabriel; Flores, Julián; Robles-García, Verónica; Arias, Pablo; Cudeiro, Javier (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 ... -
M1 inhibition dependency on slowing of muscle relaxation after brief and fast fatiguing repetitive movements: preliminary results
Madinabeitia-Mancebo, Elena; Madrid, Antonio; Cudeiro, Javier; Arias, Pablo (Springer, 2018-10-16)[Abstract] This work presents preliminary results on the association between central and peripheral expressions of muscle fatigue induced by unresisted repetitive movements. We tested cortico-spinal excitability and ... -
Mixed burst and tonic firing in the thalamus: a study in the feline lateral geniculate nucleus in vivo
Grieve, Kenneth; Rivadulla, Casto; Cudeiro, Javier (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 ... -
Modulatory effects mediated by metabotropic glutamate receptor 5 on lateral geniculate nucleus relay cells
Labra, Carmen de; Rivadulla, Casto; Cudeiro, Javier (Wiley, 2005-01-18)[Abstract] Glutamate is thought to be the excitatory neurotransmitter in the lateral geniculate nucleus (LGN) of the cat, mediating visual transmission from the retina via ionotropic receptors of both d,l-α-amino-3-hydro ... -
