The differences in the functional role for the macaque P500 and the human P600 may reflect the differentiation that has occurred in humans to support language-specific processes.
This region, based both on lesion and functional imaging studies, has become strongly associated with language-specific processes (Devlin et al., 2000; Hickok and Poppel, 2007; Price, 2010).
This interpretation would suggest that rehabilitation should be aimed at improving function in attention and executive function as much as restoring, as far as possible, language-specific processes.
Alternatively, it may reflect higher-level language-specific processes (such as language comprehension, e.g., Narain et al., 2003) as well as more general differences in language versus musical processing for a discussion of this point, see Steinbeis and Koelsch (2008).
To better understand the neurobiology of human language requires distinguishing language-specific processes from cognitive, domain-general processes not restricted to language (Bickerton & Szathmary, 2009; Fedorenko, Duncan, & Kanwisher, 2012; Friederici, 2011; Hagoort, 2005).
More importantly, this study has indicated that impaired function of these systems has an impact on final outcome, a non-language impairment that might usefully be a target for rehabilitative techniques in addition to any therapy that targets language-specific processes.
One temptation has been to suggest that right cerebral hemisphere activity in the patient group relative to the normal group, particularly when it is in or close to what might be regarded as the right hemisphere homologue of Broca's area, is a shift in the lateralization of language-specific processes.
Indeed, some native contrasts are not discriminated in certain phonological contexts by adults, due to the presence of a language-specific process that neutralizes the contrasts in those contexts.
However, the authors dismissed task-related activity as an explanation for their finding, and related it to a dynamic language-specific process contributing to recovery from aphasia after stroke.
To individuals agents within a MAS they translate as follows: Open image in new window Fig. 1 A proposed interaction among ontology, models, communication languages and domain specific processes (i) some agent views of the domain may be incomplete; that is, their individual ontologies may be incomplete.
"At the time 23andMe filed the patent, there was consideration that the technology could have potential applications for fertility clinics so language specific to the fertility treatment process was included in the patent," it said in a blog post.
