A morphological basis for orientation tuning in primary visual cortex.
Journal Article Nat Neurosci · August 2004 Featured Publication Feedforward connections are thought to be important in the generation of orientation-selective responses in visual cortex by establishing a bias in the sampling of information from regions of visual space that lie along a neuron's axis of preferred orienta ... Full text Link to item CiteThe contribution of vertical and horizontal connections to the receptive field center and surround in V1.
Journal Article Neural Netw · 2004 Here we review the results of anatomical and physiological studies in tree shrew visual cortex which focus on the contribution of vertical and horizontal inputs to receptive field center and surround properties of layer 2/3 neurons. A fundamental feature o ... Full text Link to item CiteMapping multiple features in the population response of visual cortex.
Journal Article Nature · June 26, 2003 Featured Publication Stimulus features such as edge orientation, motion direction and spatial frequency are thought to be encoded in the primary visual cortex by overlapping feature maps arranged so that the location of neurons activated by a particular combination of stimulus ...
