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 کاملAre primate lateral geniculate nucleus (LGN) cells really sensitive to orientation or direction?
There is considerable controversy over the existence of orientation and direction sensitivity in lateral geniculate nucleus (LGN) neurons. Claims for the existence of these properties often were based upon data from cells tested well beyond their peak spatial frequencies. The goals of the present study were to examine the degree of orientation and direction sensitivity of LGN cells when tested ...
متن کاملOn the impact of attention and motor planning on the lateral geniculate nucleus.
Although the lateral geniculate nucleus (LGN) is one of the most thoroughly characterized thalamic nuclei, its functional role remains controversial. Traditionally, the LGN in primates has been viewed as the lowest level of a set of feedforward parallel visual pathways to cortex. These feedforward pathways are pictured as connected hierarchies of areas designed to construct the visual image gra...
