New tools for old problems: magnetic stimulation to study (and help) the brain
Rivadulla, Casto; Aguilá Macías, Jordi; Prieto-Soler, Sandra; Aguilar, Juan; Cudeiro, Javier (Springer Nature, 2017)[Abstract] Magnetic stimulation techniques, either repetitive TMS (rTMS) or Static Magnetic Fields, allow to modulate brain activity through the skull in a non invasive and painless way. When rTMS is used, low frequencies ... -
Receptive field structure of burst and tonic firing in feline lateral geniculate nucleus
Rivadulla, Casto; Martínez Otero, Luis Miguel; Grieve, Kenneth; Cudeiro, Javier (Wiley, 2003-09-12)There are two recognised modes of firing activity in thalamic cells, burst and tonic. A low-threshold (LT) burst (referred to from now on as ‘burst’) comprises a small number of high-frequency action potentials riding the ... -
Sight and insight – on the physiological role of nitric oxide in the visual system
Cudeiro, Javier; Rivadulla, Casto (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. ... -
Specific roles of NMDA and AMPA receptors in direction-selective and spatial phase-selective responses in visual cortex
Rivadulla, Casto; Sharma, Jitendra; Sur, Mriganka (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 ... -
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. ... -
Synergistic effects of applying static magnetic fields and diazepam to improve EEG abnormalities in the pilocarpine epilepsy rat model
Labra, Carmen de; Cudeiro, Javier; Rivadulla, Casto (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 ... -
The influence of nitric oxide on perigeniculate GABAergic cell activity in the anaesthetized cat
Rivadulla, Casto; Rodríguez, R.; Martínez-Conde, Susana; Acuña, Carlos; Cudeiro, Javier (Wiley, 1996-12)[Abstract] We have tested the effect of iontophoretic application of the nitric oxide synthase inhibitor l-nitroarginine on the activity of a population of 53 perigeniculate (PGN) cells, recorded extracellularly in the ... -
The lemniscal–cuneate recurrent excitation is suppressed by strychnine and enhanced by GABAA antagonists in the anaesthetized cat
Aguilar, Juan; Soto, C.; Rivadulla, Casto; Canedo Lamas, Antonio (Wiley, 2002-11-13)[Abstract] In the somatosensory system, cuneolemniscal (CL) cells fire high frequency doublets of spikes facilitating the transmission of sensory information to diencephalic target cells. We studied how lemniscal feedback ... -
The role of glyclinergic interneurons in the dorsal column nuclei
Sánchez Vila, Eduardo; Aguilar Fernández, Jaime; Rivadulla, Casto; Canedo Lamas, Antonio (Elsevier, 2004-03-12)[Abstract] The aim of this paper is to provide new insights about the circuitry and the role of the dorsal column nuclei (DCN) in processing somatosensory information. The presence of glycinergic cells, a second type of ... -
The role of nitric oxide in the transformation of visual information within the dorsal lateral geniculate nucleus of the cat
Cudeiro, Javier; Grieve, Kenneth; Rivadulla, Casto; Rodríguez, R.; Martínez-Conde, Susana; Acuña, Carlos (Elsevier, 1994)[Abstract] We have shown that application of an inhibitor of the enzyme nitric oxide synthase (NOS) effectively suppresses the visual responses of relay cells in the dorsal lateral geniculate nucleus (dLGN) of the anaesthetized ... -
Transcranial static magnetic stimulation reduces seizures in a mouse model of Dravet syndrome
Rivadulla, Casto; Pardo-Vázquez, José L.; Labra, Carmen de; Aguilar Fernández, Jaime; Suárez Porto, Eduardo; Paz, C.; Álvarez-Dolado, Manuel; Cudeiro, Javier (Elsevier, 2023-10-24)[Abstract] Dravet syndrome is a rare form of severe genetic epilepsy characterized by recurrent and long-lasting seizures. It appears around the first year of life, with a quick evolution toward an increase in the frequency ... -
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 ... -
Visual response augmentation in cat (and macaque) LGN: potentiation by corticofugally mediated gain control in the temporal domain
Cudeiro, Javier; Rivadulla, Casto; Grieve, Kenneth (Wiley, 2001-12-24)[Abstract] Visual responses of neurons are dependent on the context of a stimulus, not only in spatial terms but also temporally, although evidence for temporally separate visual influences is meagre, based mainly on studies ...
