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 ... -
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 ... -
Specific roles of NMDA and AMPA receptors in direction-selective and spatial phase-selective responses in visual cortex
(Society of Neuroscience, 2001)[Abstract] Cells in the superficial layers of primary visual cortex (area 17) are distinguished by feedforward input from thalamic-recipient layers and by massive recurrent excitatory connections be- tween ... -
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 ... -
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 ...
