Modulatory effects mediated by metabotropic glutamate receptor 5 on lateral geniculate nucleus relay cells
(Wiley, 2005-01-18)
[Abstract] Glutamate is thought to be the excitatory neurotransmitter in the lateral geniculate nucleus (LGN) of the cat, mediating visual transmission from the retina via ionotropic receptors of both d,l-α-amino-3-hydro ...
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 ...
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. ...
The influence of nitric oxide on perigeniculate GABAergic cell activity in the anaesthetized cat
(Wiley, 1996-12)
[Abstract] We have tested the effect of iontophoretic application of the nitric oxide synthase inhibitor l-nitroarginine on the activity of a population of 53 perigeniculate (PGN) cells, recorded extracellularly in the ...

Spatial frequency tuning of orientation-discontinuity-sensitive corticofugal feedback to the cat lateral geniculate nucleus
(Wiley, 1996-01-15)
[Abstract] 1. The influence of spatial frequency on the inhibitory component of the effects mediated by feedback from the visual cortex has been examined in X and Y cells in the A laminae of the feline dorsal lateral ...
Chronic neural adaptation induced by long-term resistance training in humans
(Springer, 2006-02-28)
[Abstract] While it is known that resistance training causes changes in the central nervous system (CNS) in the initial stages of training, there have been few studies of cumulative or sustained neural adaptation to ...
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 ...
Does the Pulvinar-Lp Complex Contribute to Motor Programming?
(Elsevier, 1989)
[Abstract] Extracellular unit recording studies in the pulvinar lateral posterior complex (Pui-LP) of behaving monkeys have shown a response property not previously reported. In monkeys performing aimed arm reaching movements ...
Looking back: corticothalamic feedback and early visual processing
(Elsevier, 2006)
[Abstract] Although once regarded as a simple sensory relay on the way to the cortex, it is increasingly apparent that the thalamus has a role in the ongoing moment-by-moment processing of sensory input and in cognition. ...
