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 ...
Intracuneate mechanisms underlying primary afferent cutaneous processing in anaesthetized cats
(Wiley, 2004-06-02)
[Abstract] The cutaneous primary afferents from the upper trunk and forelimbs reach the medial cuneate nucleus in their way towards the cerebral cortex. The aim of this work was twofold: (i) to study the mechanisms used ...
Visual response augmentation in cat (and macaque) LGN: potentiation by corticofugally mediated gain control in the temporal domain
(Wiley, 2001-12-24)
[Abstract] Visual responses of neurons are dependent on the context of a stimulus, not only in spatial terms but also temporally, although evidence for temporally separate visual influences is meagre, based mainly on studies ...
Foci of orientation plasticity in visual cortex
(Nature, 2001-05-03)
[Abstract] Cortical areas are generally assumed to be uniform in their capacity for adaptive changes or plasticity1, 2, 3, 4. Here we demonstrate, however, that neurons in the cat striate cortex (V1) show pronounced ...
The lemniscal–cuneate recurrent excitation is suppressed by strychnine and enhanced by GABAA antagonists in the anaesthetized cat
(Wiley, 2002-11-13)
[Abstract] In the somatosensory system, cuneolemniscal (CL) cells fire high frequency doublets of spikes facilitating the transmission of sensory information to diencephalic target cells. We studied how lemniscal feedback ...
Effects on EEG of low (1Hz) and high (15Hz) frequency repetitive transcranial magnetic stimulation of the visual cortex: a study in the anesthetized cat
(Bentham Open, 2007-12-07)
[Abstract] Here we confirm our earlier findings that showed 1Hz rTMS over the primary visual cortex of the anesthetized cat, known to cause inhibition of the cortex, induces an increase in power in the slow, delta band of ...
Intraneural IFG-1 in cryopreserved nerve isografts increase neural regeneration and functional recovery in the rat sciatic nerve
(Oxford, 2018-07-27)
[Abstract] Background: Insulin-like growth factor 1 (IGF-1) was found to stimulate Schwann cell mitosis. Exogenous IGF-1 may improve nerve regeneration after cryopreservation.
Objective: To evaulate the effect of ...
