Pathways to language: fiber tracts in the human brain
Reads0

TLDR
The human language function is based on the grey matter of circumscribed brain regions in the frontal and the temporal cortex but moreover on the white matter fiber tracts connecting these regions, which are considered to be crucial for the evolution of human language, which is characterized by the ability to process syntactically complex sentences.About:

Large-scale brain networks in cognition: emerging methods and principles
Steven L. Bressler,Vinod Menon +1 more
TL;DR: It is argued that the emerging science of large-scale brain networks provides a coherent framework for understanding of cognition that allows a principled exploration of how cognitive functions emerge from, and are constrained by, core structural and functional networks of the brain.
Journal ArticleDOI
The Brain Basis of Language Processing: From Structure to Function
TL;DR: Networks involving the temporal cortex and the inferior frontal cortex with a clear left lateralization were shown to support syntactic processes, whereas less lateralized temporo-frontal networks subserve semantic processes.
Journal ArticleDOI
The Neural Architecture of the Language Comprehension Network: Converging Evidence from Lesion and Connectivity Analyses
TL;DR: The left MTG showed a particularly extensive structural and functional connectivity pattern which is consistent with the severity of the impairments associated with MTG lesions and which suggests a central role for this region in language comprehension.
Journal ArticleDOI
Sensorimotor Integration in Speech Processing: Computational Basis and Neural Organization
TL;DR: An integrative model of the speech-related "dorsal stream" in which sensorimotor interaction primarily supports speech production, in the form of a state feedback control architecture, and evidence shows that this influence is modulatory but not necessary for speech perception.
Journal ArticleDOI
The cortical language circuit: from auditory perception to sentence comprehension
TL;DR: The model proposed here describes the functional neuroanatomy of the different processing steps from auditory perception to comprehension as located in different gray matter brain regions, and specifies the information flow between these regions, taking into account white matter fiber tract connections.

MR diffusion tensor spectroscopy and imaging.
TL;DR: Once Deff is estimated from a series of NMR pulsed-gradient, spin-echo experiments, a tissue's three orthotropic axes can be determined and the effective diffusivities along these orthotropic directions are the eigenvalues of Deff.
Journal ArticleDOI
The cortical organization of speech processing
Gregory Hickok,David Poeppel +1 more
TL;DR: A dual-stream model of speech processing is outlined that assumes that the ventral stream is largely bilaterally organized — although there are important computational differences between the left- and right-hemisphere systems — and that the dorsal stream is strongly left- Hemisphere dominant.

Diffusion tensor imaging: Concepts and applications
D. Le Bihan,J.-F. Mangin,Cyril Poupon,Chris A. Clark,Sabina Pappatà,Nicolas Molko,Hugues Chabriat +6 more
TL;DR: The concepts behind diffusion tensor imaging are reviewed and potential applications, including fiber tracking in the brain, which, in combination with functional MRI, might open a window on the important issue of connectivity.
Journal ArticleDOI
The faculty of language: what is it, who has it, and how did it evolve?
TL;DR: It is argued that an understanding of the faculty of language requires substantial interdisciplinary cooperation and how current developments in linguistics can be profitably wedded to work in evolutionary biology, anthropology, psychology, and neuroscience is suggested.

In vivo fiber tractography using DT-MRI data
TL;DR: Fiber tract trajectories in coherently organized brain white matter pathways were computed from in vivo diffusion tensor magnetic resonance imaging (DT‐MRI) data, and the method holds promise for elucidating architectural features in other fibrous tissues and ordered media.
