Presentation Transcript
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).
