Differential feedback modulation of center and surround mechanisms in parvocellular cells in the visual thalamus
(Society of Neuroscience, 2012-11-07)
[Abstract] Many cells in both the central visual system and other sensory systems exhibit a center surround organization in their receptive field, where the response to a centrally placed stimulus is modified when a ...
Responses of primate LGN cells to moving stimuli involve a constant background modulation by feedback from area MT
(Elsevier, 2013-05-03)
[Abstract] The feedback connections from the cortical middle temporal (MT) motion area, to layer 6 of the primary visual cortex (V1), have the capacity to drive a cascaded feedback influence from the layer 6 cortico-geniculate ...
Double-blind, randomized, placebo controlled trial on the effect of 10 days low-frequency rTMS over the vertex on sleep in Parkinson’s disease
(Elsevier, 2010-07-31)
[Abstract] Objective: A recent report indicates repetitive transcranial magnetic stimulation (rTMS) improves sleep
in Parkinson’s disease (PD). The aim of this work is to evaluate the effect of 10 days rTMS on sleep ...
Controlled trial on the effect of 10 days low-frequency repetitive transcranial magnetic stimulation (rTMS) on motor signs in Parkinson´s disease
(Wiley, 2010-07-28)
[Abstract] We evaluated the effect of low-frequency rTMS
on motor signs in Parkinson’s disease (PD), under a doubleblind
placebo-controlled trial design. PD patients were randomly
assigned to received either real (n 5 ...
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 ...
Endocannabinoid CB1 receptors modulate visual output from the thalamus
(Springer, 2011-07-20)
[Abstract] Rationale Endocannabinoids have emerged as a modulatory
brain system affecting different types of synapses,
broadly distributed throughout the CNS, which explain
the diverse psychophysical effects observed ...
Anandamide activation of CB1 receptors increases spontaneous bursting and oscillatory activity in the thalamus
(Elsevier, 2014-02-05)
[Abstract] The endocannabinoid system is a modulatory system that has been strongly associated with the regulation of functions as learning and memory, pain perception and sensory physiology in many areas of the central ...
Bursting thalamic responses in awake monkey contribute to visual detection and are modulated by corticofugal feedback
(Frontiers, 2014-05-30)
[Abstract] The lateral geniculate nucleus is the gateway for visual information en route to the visual
cortex. Neural activity is characterized by the existence of two firing modes: burst and
tonic. Originally associated ...
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 ...
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 ...
