31. Rats have less than a square inch of cortex, less than humans by a factor of 500.

32. George has recorded the electrical activity of individual neurons in the temporal cortex during the three-slide show.

33. This is the first region of the cortex to which visual information is transferred.

34. Some gray matter, such as the thalamus, has an intimate back-and-forth relationship with the cerebral cortex.

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

36. Interestingly, this is also true of mammals from which the auditory cortex has been removed.

37. For just the cerebral cortex, the subtotal is about 30 billion.

38. There is also Cortex which we set up last year as a process engineering consultancy with a keen interest in environmental work.

39. Optic nerves pass from the retina to the central cortex of the brain.

40. And, little by little, the utterly unprecedented thought began buzzing around my cortex, like a gnat in a jar.

41. Yet back in the primary visual cortex, the fourth layer is the most impressive of all.

41. Sentencedict.com is a sentence dictionary, on which you can find excellent sentences for a large number of words.

42. Many anatomists identified three such stages of visual analysis in the cortex.

43. Humans have a lot of prefrontal cortex, compared to dolphins, whose motor strip is far forward in the brain.

44. In the cortex, however, the messages are rearranged to make new patterns.

45. The implications of differences in cortical organization go beyond our understanding of the cerebral cortex.

46. The fourth-layer cortical neurons receiving that thalamic input send most of their outputs up to the second and third layers of cortex.

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

48. The eyes transmit electrical signals to the visual cortex in the brain.

49. Your Reticular Activating System is firing on all cylinders, your cortex is turning somersaults.

50. The major growth of cerebral cortex, as our ancestors became fancier and fancier primates, was sideways.

51. Among them are the upper layers of cerebral cortex that manage all that interoffice stuff.

52. In the case of the visual cortex, no one knows yet.

53. But even if the totals were constant across individuals, the subtotals would still vary between different parts of the cerebral cortex.

54. It takes a lot of wrong-way impulses to start a seizure in normal cortex.

55. They are the most prolific source of cortical synapses in most areas of the cortex.

56. For much of the 1950s physiologists probed the visual cortex using the single cell recording technique.

57. The next level of control is the upper motor neuron with cells of origin in the sensorimotor cortex.

58. Experimentally, a penicillin focus is created in animals by applying penicillin in very high concentrations directly to the cortex.

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

60. For example, since all mammals have a cerebral cortex we must assume that the ancestral form also had one.
