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. ...
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 ...
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 ...
Spectroscopic measurement of cortical nitric oxide release induced by ascending activation
(Elsevier, 2014-11-25)
[Abstract] The transition from sleep to the awake state is regulated by the activation of subcortical nuclei of the brainstem (BS) and basal forebrain (BF), releasing acetylcholine and glutamate throughout the cortex and ...
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 ...
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 ...
