TLDR
It is concluded that, as in the hearing population, discourse functions involve the right hemisphere; that distinct discourse functions can be dissociated from one another in ASL; and that brain organization for linguistic spatial devices is driven by its functional role in language processing, rather than by its surface, spatial characteristics.About:

Figures
FIG. 8. Samples of AR and SJ’s drawings and block designs, showing deficits in spatial processing in both RHD deaf subjects. 
FIG. 6. Contrasting types of discourse errors in the two RHD deaf signers: Tangential utterances are very frequent in AR (60% of utterances) but essentially absent in SJ (left) and spatial errors in ASL discourse mechanisms are minimal in AR but rampant in SJ (right). 
FIG. 1. Linguistic contrasts in ASL involving crucial use of space at the lexical level, the morphological level, and the syntactic level. 
FIG. 5. Sample pictures from ‘‘Paint Story,’’ a wordless picture sequence designed to elicit spatialized discourse mechanisms of ASL.

A review of discourse and conversation impairments in patients with dementia
TL;DR: In this paper , the effects of dementia on the production and perception of discourse have been identified in patients with focal forms of neurodegenerative conditions (e.g., patients with Alzheimer's disease, Primary Progressive Aphasia, and Parkinson's disease).

Sign language aphasia.
Emily Goldberg,Argye E. Hillis +1 more
TL;DR: In this paper , the authors review the neurobiology of sign language and patterns of language deficits that follow brain injury in the deaf signing population and find that the right hemisphere likely plays a role in non-linguistic but critical visuospatial functions.
Peculiarities of metabolic changes in healthy children with different functional activity of cerebral hemispheres
TL;DR: It’s time to get used to the idea that this place doesn’t have much to do with you.

The signs of language
Edward S. Klima,Ursula Bellugi +1 more
TL;DR: The two faces of sign and sign language have been studied in this paper, where the authors compare Chinese and American signs and feature analysis of handshapes and the rate of speaking and signing.

What the hands reveal about the brain
TL;DR: This paper showed that there are primary linguistic systems passed down from one generation of deaf people to the next, which have been forged into antonomous languages and are not derived from front spoken languages.
Book ChapterDOI
The acquisition of American Sign Language.
TL;DR: The authors compare the acquisition of American Sign Language (ASLSA) with the acquisition process of spoken languages, and delineate those aspects of acquisition which are universal over languages of varying types, and those aspects which are specific to certain linguistic and modality-related typologies.
