Vasomotion and Neurovascular Coupling in the Visual Thalamus In Vivo
(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 ...
Magnetic field strength and reproducibility of neodymium magnets useful for transcranial static magnetic field stimulation of the human cortex
(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 ...
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 ...
Bilateral tDCS on primary motor cortex: effects on fast arm reaching tasks
(PLoS, 2016-08-04)
[Abstract] Background.
The effects produced by transcranial direct current stimulation (tDCS) applied to the motor system have been widely studied in the past, chiefly focused on primary motor cortex (M1) excitability. ...
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 ...
Low-cost virtual reality system in evaluation of rhythmic motor patterns in elderly and Parkinsonian patients
(MIT Press, 2014-04-30)
[Abstract] This work details a Virtual Reality (VR) system developed to evaluate
and potentially treat alterations in hand movements and central rhythm
formation in Parkinsonian and Elderly subjects. An essential feature ...
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. ...
Virtual Reality as a Tool for Evaluation of Repetitive Rhythmic Movements in the Elderly and Parkinson’s Disease Patients
(PLoS ONE, 2012-01-18)
[Abstract] This work presents an immersive Virtual Reality (VR) system to evaluate, and potentially treat, the alterations in rhythmic
hand movements seen in Parkinson’s disease (PD) and the elderly (EC), by comparison ...
