Cerebral lateralization. Biological mechanisms, associations, and pathology: II. A hypothesis and a program for research.
TL;DR: The hypothesis is that slowed growth within certain zones of the left hemisphere is likely to result in enlargement of other cortical regions, in particular, the homologous contralateral area, but also adjacent unfaffected regions.

Aphasia with predominantly subcortical lesion sites: description of three capsular/putaminal aphasia syndromes.

TL;DR: Nine cases of subcortical aphasia with capsular/putaminal (C/P) lesion sites demonstrated on computed tomographic (CT) scans did not completely resemble cases of either Broca's, Wernicke's, global, or thalamic aphasias in neurologic findings, CT scan lesion Sites, or language behavior.

Subcortical functions in language: a working model.
TL;DR: A model of subcortical language functions that focuses on dynamic interactions between the cortex, the thalamus, and the basal ganglia in the production of spoken language and consistency with classical syndromes of aphasia and potential applications to other areas in the neurosciences are discussed.
Journal ArticleDOI
Dyslexia and brain morphology.
TL;DR: Results of CT/MRI studies suggest that in the brains of dyslexics there is an increased incidence of symmetry in the region of the planum temporale and parietooccipital cortex that may be associated with language delay and handedness.

Nonhemorrhagic infarction of the thalamus: behavioral, anatomic, and physiologic correlates.
TL;DR: Five patients with nonhemorrhagic thalamic infarction with neuropsychological tests, CT, and somatosensory evoked responses (SERs) had abnormalities of language, memory, visuospatial processing, intellect, and personality—changes compatible with dementia.

Speech and Brain-Mechanisms.
TL;DR: The story of aphasia is well summarized in two scholarly and critical chapters by Roberts (Chaps. IV and VI) as mentioned in this paper, which modestly sum up their important contributions as follows: "In conclusion, the first sure evidence that physicians might hope to distinguish functional units within the brain, appeared about one hundred years ago with the discovery of a speech mechanism within one hemisphere".
