• It delivers long-range inhibition among different portions of the space map in the optic tectum (OT), thereby mediating stimulus competition in the OT. (jneurosci.org)

  • Instead of accepting that assumption, he attached electrodes to the frog's optic nerve so he could eavesdrop on the signals it sent. (wikipedia.org)
  • By analyzing the signals the optic nerve produced when viewing the objects, Lettvin and his collaborators demonstrated the concept of "feature detectors"-neurons that respond to specific features of a visual stimulus, such as edges, movement, and changes in light levels. (wikipedia.org)
  • There is currently no treatment available for loss of vision due to optic nerve atrophy or retinal ganglion cell loss, which can be caused by end-stage glaucoma, traumatic optic atrophy, 2 and other diseases. (nature.com)

  • A variety of eye optics designs, photoreceptor matrices, and post-receptoral retinal, tectal, and cortical mechanisms allows for environmental mapping and the neural representation of the visual information available to the animal. (scielo.br)
