The lateral geniculate nucleus
The lateral geniculate nucleus (LGN) is a huge embarrassment to visual neuroscientists. Virtually all the visual information that leaves the retina to be analysed in the visual cortex is relayed through synapses in this nucleus. It is a dogma of neurophysiology that the cost imposed by putting a synapse in any pathway must be repaid by some benefit in terms of processing. Unfortunately it is no...
متن کاملThe multifunctional lateral geniculate nucleus.
Providing the critical link between the retina and visual cortex, the well-studied lateral geniculate nucleus (LGN) has stood out as a structure in search of a function exceeding the mundane 'relay'. For many mammals, it is structurally impressive: Exquisite lamination, sophisticated microcircuits, and blending of multiple inputs suggest some fundamental transform. This impression is bolstered ...
متن کاملA Model of Feedback to the Lateral Geniculate Nucleus
Simplified models of the lateral geniculate nucles (LGN) and striate cortex illustrate the possibility that feedback to the LG N may be used for robust, low-level pattern analysis. The information fed back to the LG N is rebroadcast to cortex using the LG N 's full fan-out, so the cortex-LGN-cortex pathway mediates extensive cortico-cortical communication while keeping the number of necessary c...
متن کاملCytoarchitecture of the dorsal lateral geniculate nucleus in the rabbit.
The cytoarchitecture and morphometry of the neurons in the alpha E sector of the dorsal lateral geniculate nucleus of the rabbit have been studied. The preparation techniques used were those of Golgi-Adams and Klüver-Barrera. Our method was to subdivide the alpha E sector into three zones (superior, medial and inferior) and then to cut each zone along the horizontal, transverse and saggital pla...
متن کاملEfficient coding of natural scenes in the lateral geniculate nucleus: experimental test of a computational theory.
A recent computational theory suggests that visual processing in the retina and the lateral geniculate nucleus (LGN) serves to recode information into an efficient form (Atick and Redlich, 1990). Information theoretic analysis showed that the representation of visual information at the level of the photoreceptors is inefficient, primarily attributable to a high degree of spatial and temporal co...
