1. Basic Bits of Neuronal Grammar Friedemann Pulvermller MRC Cognition and Brain Sciences Unit Cambridge

2. Activity states: Ignition -- full activation, momentary Reverberation -- continuous enhanced activity following ignition Priming -- parasitic activity caused by strongly connected sets Rest -- inactivity

3. Activity states: Darker colours denote reduced activity states

4. The network:

5. The represent ed elements: WORDS SEQUENCE FEATURES

6. The represent ing elements: WORD WEBS

7. The represent ing elements: WORD WEBS SEQUENCE DETECTORS (SDs)

8. I 3 word input congruent with the network structure

9. The sentence Betty get up will appear in the input and will not be accepted by the network

10. Time step / Input / Process

11. 0 -- All webs at rest

12. 1 Betty Ignition of word web

13. 2 -- Priming of SD

14. 3 -- Priming of SD

15. 4 -- Priming of word web

16. 5 gets Primed ignition of word web

17. 6 -- Priming of SDs Backward ignition

18. 7 -- Priming of SDs Backward ignition

19. 8 -- Priming of word web Backward ignition

20. 9 -- --

21. 10 up Ignition of word web

22. 11 -- Backward ignition

23. 12 -- Backward ignition

24. 13 -- Backward ignition

25. 14 -- Backward ignition

26. 15 -- Backward ignition

27. 16 -- Backward ignition

28. 17 -- Backward ignition

29. 18 -- Deactivation

30. At time step 17, the 3 criteria for string acceptance were met: All activated word webs were visible (i.e., reverberated at the highest reverberation level). All activate word webs were satisfied (i.e., their set of sequence detectors reverberated at a high level). All active sets were synchronized (I.e., participated in a continuous wave of ignitions).

32. II 3 word input in congruent with the network structure

33. The sentence Up get Betty will appear in the input and will not be accepted by the network

34. Time step / Input / Process

35. 0 -- All webs at rest

36. 1 up Ignition of word web

37. 2 -- --

38. 3 -- --

39. 4 get Unprimed ignition I^ of word web

40. 5 -- Priming of SD Threshold regulation

41. 6 -- Priming of SD

42. 7 -- Priming of SD

43. 8 Betty Unprimed ignition I^ of word web

44. 9 -- Priming of SD Threshold regulation

45. 10 -- Priming of SD

46. 11 -- Priming of SD

47. At time step 10, the 3 criteria for string acceptance were not met: Only 1 word web was visible (the 2 others were at lower activity levels, R2 and R3; cf. darker colours). No one of the 3 word webs was satisfied (SDs did not reverberate). No final synchronization process.

49. III 3 word input partly in congruent with the network structure

50. The sentence Up Betty get will appear in the input and will not be accepted by the network

51. Time step / Input / Process

52. 0 -- All webs at rest

53. 1 up Ignition of word web

54. 2 -- --

55. 3 -- --

56. 4 Betty Unprimed ignition I^ of word web

57. 5 -- Priming of SD Threshold regulation

58. 6 Betty Priming of SD

59. 7 -- Priming of word web

60. 8 get Primed ignition of word web

61. 9 -- Priming of SD Backward ignition

62. 10 -- Priming of SD Backward ignition

63. 11 -- Backward ignition

64. 12 -- --

65. At time step 12, not all of the 3 string acceptance criteria were met: 2 out of the 3 activated word webs were visible (i.e., reverberated at the highest reverberation level). Only 1 out of 3 word webs were satisfied (i.e., their set of sequence detectors reverberated at a high level). Only 2 out of the 3 word webs were synchronized (I.e., participated in a continuous wave of ignitions).
