Emergent version: 4.0.19
Each plot present FSD trajectories of four pairs of correlated words (see figure legend).
Only neural activations from the Semantics layer are shown.
FSD parameters are included in the figures.
Proportion of units in the layer to lesion (lesion_pct parameter in Emergent) is written above each figure.

OP_Hid Layer Lesion
Lesion of hidden layer between Orthography and Phonology with an intact semantic pathway.
| lesion pct = 0 | lesion pct = 0.2 | lesion pct = 0.4 | lesion pct = 0.6 | lesion pct = 0.8 | lesion pct = 1 |

Semantic Pathway Lesions
Completely Lesioned Direct Pathway

OS_Hid_DIRECT_FULL Lesion
Lesion of hidden layer between Orthography and Semantics. No direct pathway (full lesion of hidden layer between Orthography and Phonology).
| lesion pct = 0 | lesion pct = 0.2 | lesion pct = 0.4 | lesion pct = 0.6 | lesion pct = 0.8 | lesion pct = 1 |

Full lesion of OS_Hid and OP_Hid layers (OS_Hid_DIRECT_FULL lesion with lesion pct = 1).
Ten trajectories of word 'deer':
SP_Hid_DIRECT_FULL Lesion
Lesion of hidden layer between Phonology and Semantics. No direct pathway (full lesion of hidden layer between Orthography and Phonology).
| lesion pct = 0 | lesion pct = 0.2 | lesion pct = 0.4 | lesion pct = 0.6 | lesion pct = 0.8 | lesion pct = 1 |

Intact Direct Pathway

OS_Hid Layer Lesion
Lesion of hidden layer between Orthography and Semantics with an intact direct pathway.
Important: The scale of the plots is larger than the scale of the above plots.
| lesion pct = 0 | lesion pct = 0.2 | lesion pct = 0.4 | lesion pct = 0.6 | lesion pct = 0.8 | lesion pct = 1 |

SP_Hid Layer Lesion
Lesion of hidden layer between Phonology and Semantics with an intact direct pathway.
Important: The scale of the plots is larger than the scale of the above plots except for OS_Hid layer lesion (they have both the same scale).
| lesion pct = 0 | lesion pct = 0.2 | lesion pct = 0.4 | lesion pct = 0.6 | lesion pct = 0.8 | lesion pct = 1 |
