Suppression of V1 feedback produces a shift in the topographic representation of receptive fields of LGN cells by unmasking latent retinal drives
(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. ... -
Synaptic Integration by V1 Neurons Depends on Location Within the Orientation Map
(Elsevier/Cell Press, 2002)[Abstract] Neurons in the primary visual cortex (V1) are organized into an orientation map consisting of orientation domains arranged radially around “pinwheel centers” at which the representations of all orientations ... -
Synergistic effects of applying static magnetic fields and diazepam to improve EEG abnormalities in the pilocarpine epilepsy rat model
(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 ... -
Temporal Dynamics of Muscle, Spinal and Cortical Excitability and Their Association With Kinematics During Three Minutes of Maximal-Rate Finger Tapping
(Springer Nature, 2020-02-21)[Abstract] We tested peripheral, spinal and cortical excitability during 3 minutes of unresisted finger tapping at the maximal possible rate, which induced fatigue. Subsequently, we studied the temporal dynamics of muscle ... -
Temporal variability of gait in Parkinson disease: effectsof a rehabilitation programme based on rhythmic sound cuesTemporal variability of gait in Parkinson disease: effectsof a rehabilitation programme based on rhythmic sound cues
(Elsevier, 2004)[Abstract] It has been suggested that sequential movements in patients with Parkinson's disease (PD) might be improved by the effects of external rhythmic cues. We studied spatiotemporal gait parameters and temporal gait ... -
The cold-sensing ion channel TRPM8 regulates central and peripheral clockwork and the circadian oscillations of body temperature
(Wiley, 2022-10-17)[Abstract] Aim: Physiological functions in mammals show circadian oscillations, synchronized by daily cycles of light and temperature. Central and peripheral clocks participate in this regulation. Since the ion channel ... -
The effects of expectancy on corticospinal excitability: passively preparing to observe a movement
(American Physiological Society, 2014-01-08)[Abstract] The corticospinal tract excitability is modulated when preparing movements. Earlier to movement execution, the excitability of the spinal cord increases waiting for supraspinal commands to release the movement. ... -
The Implications of the Foot Health Status in Parkinson Patients: A Case–Control Study
(Wiley, 2022-05-17)[Abstract] Parkinson's disease (PD) is a neurodegenerative disorder that affects both health of the feet, as to gait patterns. This study aimed to find out about foot problems and their impact on self-perceived quality of ... -
The influence of nitric oxide on perigeniculate GABAergic cell activity in the anaesthetized cat
(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
(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 mechanistic foundation of Weber’s law
(Nature, 2019-08-12)[Abstract] Although Weber's law is the most firmly established regularity in sensation, no principled way has been identified to choose between its many proposed explanations. We investigated Weber's law by training rats ... -
The operating regime of local computations in primary visual cortex
(Oxford University Press, 2009-02-16)[Abstract] In V1, local circuitry depends on the position in the orientation map: close to pinwheel centers, recurrent inputs show variable orientation preferences; within iso-orientation domains, inputs are relatively ... -
The primate pulvinar nuclei: vision and action
(Elsevier, 2000)[Abstract] The pulvinar nuclei of the thalamus are proportionately larger in higher mammals, particularly in primates, and account for a quarter of the total mass. Traditionally, these nuclei have been divided into oral ... -
The role of glyclinergic interneurons in the dorsal column nuclei
(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
(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 ... -
Tonic and bursting activity in the cuneate nucleus of the chloralose-anesthetized cat
(Elsevier, 1998)[Abstract] Whole-cell recordings were obtained from cuneate neurons in anesthetized, paralysed cats. Stimulation of the contralateral medial lemniscus permitted us to separate projection cells from presumed interneurons. ... -
Transcranial magnetic stimulation over dorsolateral prefrontal cortex in Parkinson’s disease
(Elsevier, 2006-11-09)[Abstract] Objective Several studies have shown that repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) is effective in the treatment of depression in patients with ... -
Transcranial static magnetic field stimulation of the human motor cortex
(Wiley, 2001-08-01)[Abstract] The aim of the present study was to investigate in healthy humans the possibility of a non-invasive modulation of motor cortex excitability by the application of static magnetic fields through the scalp. Static ... -
Transcranial static magnetic stimulation reduces seizures in a mouse model of Dravet syndrome
(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 ...
