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 ...
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 ...
The primate pulvinar nuclei: vision and action
(Elsevier, 2000)
[Abstract] The pulvinar nuclei of the thalamus are proportionately larger in higher mammals, particularly in primates, and account for a quarter of the total mass. Traditionally, these nuclei have been divided into oral ...
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 ...
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 ...
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 ...
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 ...
Cannabis, endocannabinoid CB1 receptors, and the neuropathology of vision
(Elsevier, 2016)
[Abstract] Cannabinoid (CB) receptors are widely distributed through the central nervous system, where they play a relevant role in various cognitive processes such as learning, memory, or attention. However, despite the ...
