Changes in Visual Responses in the Feline dLGN: Selective Thalamic Suppression Induced by Transcranial Magnetic Stimulation of V1
(Oxford University Press, 2006-08-14)
[Abstract] Transcranial magnetic stimulation (TMS) of the cortex can modify activity noninvasively and produce either excitatory or inhibitory effects, depending on stimulus parameters. Here we demonstrate controlled ...
Cortical Modulation of the Transient Visual Response at Thalamic Level: A TMS Study
(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 ...
Effects on EEG of low (1Hz) and high (15Hz) frequency repetitive transcranial magnetic stimulation of the visual cortex: a study in the anesthetized cat
(Bentham Open, 2007-12-07)
[Abstract] Here we confirm our earlier findings that showed 1Hz rTMS over the primary visual cortex of the anesthetized cat, known to cause inhibition of the cortex, induces an increase in power in the slow, delta band of ...
Effects of movement imitation training in Parkinson's disease: a virtual reality pilot study
(Elsevier, 2016-05)
[Abstract] Background. Hypometria is a clinical motor sign in Parkinson's disease. Its origin likely emerges from basal ganglia dysfunction, leading to an impaired control of inhibitory intracortical motor circuits. Some ...
Different sources of nitric oxide mediate neurovascular coupling in the lateral geniculate nucleus of the cat
(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 ...
Balancing the excitability of M1 circuitry during movement observation without overt replication
(Frontiers, 2014-09-17)
[Abstract] Although observation of a movement increases the excitability of the motor system
of the observer, it does not induce a motor replica. What is the mechanism for
replica suppression? We performed a series of ...
Validity of the finger tapping test in Parkinson’s disease, elderly and young healthy subjects: is there a role for central fatigue?
(Elsevier, 2012-05-03)
[Abstract] Objective: The main goal of this work is to evaluate the validity of the finger tapping test (FT) to detect alterations in rhythm formation.
Methods: We use FT to study the alterations in motor rhythm in three ...
Antagonist muscle co-activation during straight walking and its relation to kinematics: Insight from young, elderly and Parkinson's disease
(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. In the
healthy subjects this ...
Motor facilitation during real-time movement imitation in Parkinson’s disease: a virtual reality study
(Elsevier, 2013-08-06)
[Abstract] Background: Impaired temporal stability and poor motor unit recruitment are key impairments in Parkinsonian motor control during a whole spectrum of rhythmic movements, from simple finger tapping to gait. Therapies ...
Spatiotemporal gait patterns during overt and covert evaluation in patients with Parkinson’s disease and healthy subjects: is there a hawthorne effect?
(Human Kinetics, 2015)
[Abstract] Parkinson's disease (PD) and aging lead to gait impairments. Some of the disturbances of gait are focused on step length, cadence, and temporal variability of gait cycle. Under experimental conditions gait can ...
