Self organising cortical maps in V1 layer 4C, with realistic LGN spatiotemporal receptive fields (PhD)

Primary visual cortex has map like representations (topographic maps) for a number of visual features, this means that neighbouring neurons in this region of the brain are activated by similar visual stimuli. Two of the visual features which are as yet poorly characterised are spatial frequency (parallel lines of different frequencies) and temporal frequency (the frequency of a flashing light). Both are essential for full visual scene and object motion representation. By the inclusion of realistic spatiotemporal receptive fields in the early stages of the visual pathway, it is hoped to develop topographic maps for these features and investigate their relationships with other feature maps.
