Population receptive fields of ON and OFF thalamic inputs to an orientation column in visual cortex
The primary visual cortex of primates and carnivores is organized into columns of neurons with similar preferences for stimulus orientation, but the developmental origin and function of this… Expand
PRINCIPLES UNDERLYING SENSORY MAP TOPOGRAPHY IN PRIMARY VISUAL CORTEX
The primary visual cortex contains a detailed map of the visual scene, which is represented according to multiple stimulus dimensions including spatial location, ocular dominance and stimulus… Expand

Images are processed in the primary visual cortex by neurons that encode different stimulus orientations and spatial phases. In primates and carnivores, neighboring cortical neurons share similar… Expand
DualSPHysics: towards high performance computing using SPH technique
- J. M. Alonso
La dinamica de fluidos computacional (CFD) proporciona una valiosa herramienta para la investigacion cientifica. Por un lado permite simular experimentos numericos en lugar de reproducir experiencias… Expand
Mixing of Chromatic and Luminance Retinal Signals in Primate Area V1.
Vision emerges from activation of chromatic and achromatic retinal channels whose interaction in visual cortex is still poorly understood. To investigate this interaction, we recorded neuronal… Expand

Stimulus orientation in the primary visual cortex of primates and carnivores is mapped as iso-orientation domains radiating from pinwheel centres, where orientation preferences of neighbouring cells… Expand
Thalamocortical processing in vision.
Visual information reaches the cerebral cortex through a major thalamocortical pathway that connects the lateral geniculate nucleus (LGN) of the thalamus with the primary visual area of the cortex… Expand

Parallel perception of multiple orientations is essential for identification of patterns and 3-D shapes from texture. While the primary visual cortex of primates and carnivores is organized in… Expand
Thalamus controls recurrent cortical dynamics
Previous work has suggested that cortical recurrent circuits can self-sustain their activity without thalamic input. A study now demonstrates that this is not the case in the awake brain, which… Expand
