[Communication, language and the brain: from past anterior to near future].
The goal of this article is to share some reflection on the astonishing evolution of the ideas in communication neuroscience and neurolinguistics over the last 30 years, since the founding of the société de neuropsychologie de langue française. in particular, a number of conceptual and methodological advancements have characterized this period, many of which have been lead or heavily contributed by french-speaking research groups in that field. among the advances discussed, are (a) the widening to discourse and pragmatic components of the concept of language, as well as the theoretical and clinical implication of this conceptual extension, (b) the unique contribution of anatomical and functional neuroimaging, (c) the massive impact of the cognitive revolution on theoretical frameworks of language components, and its influence on therapy, (d) the disappearance and the re-appearance of the brain in the main stream research on language over this period, (e) the new perspectives offered though attention put on social aspects of language and the social participation of the individual with language disorders, (f) the emergence of a genuine science of aphasia rehabilitation, and (g) the rediscovery of inter-individual characteristics both genetically- and environmentally- determined. The authors then risk themselves in trying to envision what could characterize the evolution in the field for the next 30 years. Though perilous, this speculative exercise allowed to pinpoint to a number of anticipated advancements including (a) a probable reconciliation between cognitive and connectionist models to the benefit of both visions, (b) an increased contribution of social and emotional neurosciences, (c) some inescapable technological advancements, including light portable neuroimaging devices which will allow to study the neurobiological bases of communication in natural contexts, (d) the integration between communication and aging in cognitive neuroscience and (e) the development of new research fields at some unexpected cross-roads (e.g., physical activity and communication ?) as well as the description of new types of aphasia (e.g., towards a chat aphasia !). Taken together, the advancements made over the 30 last years, and the perspective of future development, confirms the premier role of cognitive neuroscience of language and neurolinguistics in setting the pace through innovative approaches that allow unveiling the mysteries of the mutual relationships between brain and cognition.
