The amblyopic deficit and its relationship to geniculo-cortical processing streams.
Amblyopia or lazy eye is the most common cause of uniocular blindness in adults and is caused by a disruption to normal visual development as a consequence of unmatched inputs from the two eyes in early life, arising from a turned eye (strabismus), unequal refractive error (anisometropia), or form deprivation (e.g., cataract). Using high-field functional magnetic resonance imaging in a group of...
متن کاملFactors limiting contrast sensitivity in experimentally amblyopic macaque monkeys
Contrast detection is impaired in amblyopes. To understand the contrast processing deficit in amblyopia, we studied the effects of masking noise on contrast threshold in amblyopic macaque monkeys. Amblyopia developed as a result of either experimentally induced strabismus or anisometropia. We used random spatiotemporal broadband noise of varying contrast power to mask the detection of sinusoida...
متن کاملDifferential architecture of multisynaptic geniculo-cortical pathways to V4 and MT.
Parallel visual pathways in the primate brain known as the dorsal and ventral streams receive retinal inputs mainly through the magnocellular (M) and parvocellular (P) layers of the lateral geniculate nucleus. Inputs from these layers terminate within distinct parts of layer 4C of V1 (visual area 1). Due to the complexity of M- and P-derived neural connectivity in V1 and higher visual areas, th...
متن کاملThe amblyopic deficit for 2nd order processing: Generality and laterality
A number of previous reports have suggested that the processing of second-order stimuli by the amblyopic eye (AE) is defective and that the fellow non-amblyopic eye (NAE) also exhibits an anomaly. Second-order stimuli involve extra-striate as well as striate processing and provide a means of exploring the extent of the cortical anomaly in amblyopia using psychophysics. We use a range of differe...
متن کاملCortical deficits in human amblyopia: their regional distribution and their relationship to the contrast detection deficit.
PURPOSE The understanding of the site and nature of the cortical processing deficit in human amblyopia awaits the resolution of three fundamental questions about which there is, at present, much controversy: First, is area V1 affected as the present animal models would predict, but some imaging studies argue against? Second, how extensive is the loss of extrastriate function, and does it simply...
