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 ...
Tonic and bursting activity in the cuneate nucleus of the chloralose-anesthetized cat
(Elsevier, 1998)
[Abstract] Whole-cell recordings were obtained from cuneate neurons in anesthetized, paralysed cats. Stimulation of the contralateral medial lemniscus permitted us to separate projection cells from presumed interneurons. ...
Lemniscal recurrent and transcortical influences on cuneate neurons
(Elsevier, 2000)
[Abstract] Intracellular recordings were obtained from cuneate neurons of chloralose-anesthetized, paralysed cats to study the synaptic responses induced by electrical stimulation of the contralateral medial lemniscus. ...
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. ...
Always returning: feedback and sensory processing in visual cortex and thalamus
(Elsevier, 2006-05-19)
[Abstract] Feedback projections are an integral part of the mammalian visual system. Although it is tempting to relegate them to a subsidiary role in visual processing, because their supposed latency and lag might appear ...
Actions of compounds manipulating the nitric Oxide system in the cat primary visual cortex
(Wiley, 1997-10)
[Abstract:] We iontophoretically applied NG-nitro-L-arginine (l-NOArg), an inhibitor of nitric oxide synthase (NOS), to cells (n= 77) in area 17 of anaesthetized and paralysed cats while recording single-unit activity ...
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 ...

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 ...
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 ...
