Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1878 first instalment in Brain. Its 1879 continuations, Jackson’s other aphasia writings, competing localization accounts and later language-neuroscience models remain separate.
