Bootstrap testing for cross-correlation under low firing activity
(Springer, 2015-04-14)
[Abstract] A new cross-correlation synchrony index for neural activity is proposed. The index is based on the integration of the kernel estimation of the cross-correlation function. It is used to test for the dynamic ...
Functional two-way analysis of variance and bootstrap methods for neural synchrony analysis
(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, ...
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 ...
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 ...
Cross nearest-spike interval based method to measure synchrony dynamics
(American Institute of Mathematical Sciences, 2014-02)
[Abstract] A new synchrony index for neural activity is de ned in this paper.
The method is able to measure synchrony dynamics in low ring rate scenarios.
It is based on the computation of the time intervals between ...
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 ...
Central fatigue induced by short-lasting finger tapping and isometric tasks: a study of silent periods evoked at spinal and supraspinal levels
(Elsevier, 2015-08-01)
[Abstract] The neural substrates of fatigue induced by muscular activity have been addressed in depth in relation to isometric tasks. For these activities, when fatigue develops, it has been noted that the duration of the ...
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 ...
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 ...
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. ...
