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. ...
Sight and insight – on the physiological role of nitric oxide in the visual system
(Elsevier, 1999-03-01)
[Abstract] Research in the fields of cellular communication and signal transduction in the brain has moved very rapidly in recent years. Nitric oxide (NO) is one of the latest discoveries in the arena of messenger molecules. ...
Completing the corticofugal loop: a visual role for the corticogeniculate Type 1 metabotropic glutamate receptor
(Society of Neuroscience, 2002-04-01)
[Abstract] The way in which the brain deals with sensory information relies
not only on feedforward processing of signals from the periph-
ery but also on feedback inputs. This is the case of the massive
projection back ...
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 ...
Different sources of nitric oxide mediate neurovascular coupling in the lateral geniculate nucleus of the cat
(Frontiers, 2009-09-08)
[Abstract] Understanding the link between neuronal responses (NRs) and metabolic signals is fundamental to our knowledge of brain function and it is a milestone in our efforts to interpret data from modern non invasive ...
