9. But that visual cortex is itself divided into discrete modules that perform different visual functions.

10. Areas of the visual cortex responsible for recognizing complex visual scenes as well as the anterior cingulate gyrus, which governs attention and motivation, are also active during REM sleep.

11. For instance, the visual cortex of the human brain is estimated to operate at roughly one petaflop — one quadrillion floating point operations per second.

12. The visual cortex is activated by merely imagining a musical score.

13. The visual cortex response related with the visual field defects induced in function MRI.

14. For example, our visual system maps visual space on to the surface of our visual cortex.

15. Part of the problem is that they are often on tasks that are also severely impaired after destruction of primary visual cortex.

16. You find that cells in adjacent parts of the visual cortex are activated by stimulation in adjacent parts of the visual field.

17. Matters are further complicated by the fact that information from the two eyes is brought together in the primary visual cortex.

18. When applied to the newly discovered cytochrome oxidase blobs in the visual cortex of primates the correlational approach is quite revealing.

19. This suggests that the visual mechanisms involved in discrimination performance change after visual cortex ablation.

20. We have already seen that there are cells in the visual cortex that recognize edges.

21. It can also influence learned and voluntary reactions to visual stimuli when the visual cortex is absent.

22. The strongest evidence for such a contribution comes from studying the effects of removal of the primary visual cortex.

23. Indeed, it is extremely difficult to distinguish between the primary visual cortex and surrounding areas in this species.

24. Surely, everyone thought, something fancy happened in those six layers, all of which send axons to the visual cortex.

25. Lab scientists can reconstruct simple black-and-white images the subject is viewing by analyzing the blood flow in the brain's visual cortex.

25. is a online sentence dictionary, on which you can find excellent sentences for a large number of words.

26. Refers to a collection of axons coursing from the lateral geniculate body to the visual cortex.

27. It is extremely phospherescent due to the amount of phosphene that it transmits onto the visual cortex.

28. A World War I soldier with a small-bore bullet wound in the back of his head might also, for instance, have a vacancy in his field of vision caused by a corresponding injury in his visual cortex.

29. For instance, from birth the auditory cortex will receive only sound or the visual cortex will receive only visual input.

30. The system — it detects brain signals from the user's visual cortex — is rigged to boss around a small robot with a laptop on its back.

31. The lesions involved geniculocalcarine tract to occipital visual cortex caused visual defect and produced cortical blindness.

32. Dramatic response in the central part of the occipital lobe, which was related to white light stimuli, located at primary visual cortex.

33. NOS - positive neurons were present in LGN, visual cortex and parietal cortex.

34. Objective To study the effects of strabismus on the development of the neurons in lateral geniculate nuclei (LGN) and visual cortex in cats.

35. The c - fos in pregeniculum , rostral cerebral ganglion and visual cortex takes part in the injury.

36. These signals, known as PGO waves, originate in the visual cortex and in two other visual regions of the brain: the pons and the lateral geniculate nucleus.

37. Mixed high - valence facial expressions are processed within temporal lobe visual cortex, thalamus, and amygdalohippocampal complex.

38. This experiment provides a fast and relatively accurate method to calculate the retinotopic eccentricities in a large cortical area of the visual cortex.

39. In blind people all this brain power would go to waste, but somehow an unsighted person's brain rewires itself to connect auditory regions of the brain to the visual cortex.

40. Conclusion : There is synchronous development in the microvascular of the homologous region between infant lateral geniculate body and visual cortex.

41. The investigators reasoned that if the synesthetes did have highly excitable neurons in the visual cortex, they would need less stimulation than the control subjects to see the phosphene.

42. The neurons of the LGN then relay the visual image to the primary visual cortex (V1) which is located at the back of the brain ( caudal end) in the occipital lobe in and close to the calcarine sulcus.

43. Also, some regions of cerebral cortex that border visual and auditory cortices—the left fusiform gyrus, for example—expand territory in blind people to make use of the idle circuitry in visual cortex.

44. Visual Evoked Potentials (VEPs) are produced by electrical activity of the visual cortex in response to light or pattern stimulation of the retina.

45. Since the work of Hubel and Wiesel, it is generally accepted that visual orientation and direction selectivity are achieved by processes in the visual cortex in the higher mammals.

46. This article briefly introduces current opinions on SP in molecular neurobiology and the distribution and function in retina,[http:///visual cortex.html] lateral geniculate nucleus and visual cortex.

47. Anisometropic amblyopia has the neural undersampling at a high spatial frequency in the secondary visual cortex as compared to amblyopic amblyopia.

48. Each participant received stimulation on the scalp near an area called the primary visual cortex until they saw a flash of light known as a phosphene.

49. Visual cortex has the functional column system which performs these complex functions.
