Bilateral Congenital Anophthalmos and Agenesis of the Optic Pathways
This report presents a rare example of a bilateral congenital anophthalmos and an agenesis of the optic pathways. The MR imaging studies revealed that the eyeballs, optic nerves, optic chiasm, optic tracts and optic radiation were absent. The chromosomal examination was normal. Mild mental retardation was also observed. Apart from the rarity of the anophthalmos and the total absence of the opti...
متن کاملReciprocating tachycardia using bilateral anomalous pathways: electrophysiologic and clinical implications.
A patient who had disabling supraventricular tachycardia showed electrophysiologic evidence of coexistent right and left Kent bundles. The supraventricular tachycardia was accelerated by sequential antegrade and retrograde conduction over the right and left Kent bundles, respectively. Spontaneous blocking of the conduction through the right Kent bundle was associated with a slowing of the tachy...
متن کاملNeural pathways for bilateral vocal control in songbirds.
Ipsilateral and contralateral projections of nucleus robustus archistriatalis (RA), a telencephalic vocal premotor nucleus, to respiratory-vocal nuclei in the brainstem were defined in adult male Wasserschlager canaries, grey catbirds, and zebra finches, three songbird species that appear to differ in the degree of lateralized syringeal dominance. In all three species, ipsilateral projections o...
متن کاملDistinct Corticostriatal and Intracortical Pathways Mediate Bilateral Sensory Responses in the Striatum
Individual striatal neurons integrate somatosensory information from both sides of the body, however, the afferent pathways mediating these bilateral responses are unclear. Whereas ipsilateral corticostriatal projections are prevalent throughout the neocortex, contralateral projections provide sparse input from primary sensory cortices, in contrast to the dense innervation from motor and fronta...
متن کاملSubcortical pathways to extrastriate visual cortex underlie residual vision following bilateral damage to V1
Residual vision, or blindsight, following damage to the primary visual cortex (V1) has been investigated for almost half a century. While there have been many studies of patients with unilateral damage to V1, far fewer have examined bilateral damage, mainly due to the rarity of such patients. Here we re-examine the residual visual function and underlying pathways of previously studied patient S...
