Anandamide activation of CB1 receptors increases spontaneous bursting and oscillatory activity in the thalamus
Dasilva, Miguel; Grieve, Kenneth; Cudeiro, Javier; Rivadulla, Casto (Elsevier, 2014-02-05)[Abstract] The endocannabinoid system is a modulatory system that has been strongly associated with the regulation of functions as learning and memory, pain perception and sensory physiology in many areas of the central ... -
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 ... -
Can pathway-specific LFPs be obtained in cytoarchitectonically complex structures?
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 ... -
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 ... -
Different sources of nitric oxide mediate neurovascular coupling in the lateral geniculate nucleus of the cat
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 ... -
Effects of static magnetic fields on the visual cortex: reversible visual deficits and reduction of neuronal activity
Aguilá Macías, Jordi; Cudeiro, Javier; Rivadulla, Casto (Oxford, 2014-09-26)[Abstract] Noninvasive brain stimulation techniques have been successfully used to modulate brain activity, have become a highly useful tool in basic and clinical research and, recently, have attracted increased attention ... -
Endocannabinoid CB1 receptors modulate visual output from the thalamus
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 ... -
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 ... -
Intraneural IFG-1 in cryopreserved nerve isografts increase neural regeneration and functional recovery in the rat sciatic nerve
González Porto, Sara Alicia; Doménech, Nieves; Blanco García, Francisco J; Centeno, Alberto; Rivadulla, Casto; Álvarez Jorge, Álvaro; Sánchez Ibáñez, Jacinto; Rendal Vázquez, María Esther (Oxford, 2018-07-27)[Abstract] Background: Insulin-like growth factor 1 (IGF-1) was found to stimulate Schwann cell mitosis. Exogenous IGF-1 may improve nerve regeneration after cryopreservation. Objective: To evaulate the effect of ... -
Magnetic field strength and reproducibility of neodymium magnets useful for transcranial static magnetic field stimulation of the human cortex
Rivadulla, Casto; Foffani, Guglielmo; Oliviero, Antonio (Wiley, 2013-10-11)[Abstract] Objective. The application of transcranial static magnetic field stimulation (tSMS) in humans reduces the excitability of the motor cortex for a few minutes after the end of stimulation. However, when tSMS is ... -
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 ... -
Static magnetic fields reduce epileptiform activity in anesthetized rat and monkey
Rivadulla, Casto; Aguilar, Juan; Coletti, Marcos; Aguila, Jordi; Prieto, Sandra; Cudeiro, Javier (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
Aguila, Jordi; Cudeiro, Javier; Rivadulla, Casto (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. ... -
Vasomotion and Neurovascular Coupling in the Visual Thalamus In Vivo
Rivadulla, Casto; Labra, Carmen de; Grieve, Kenneth; Cudeiro, Javier (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 ...
