This study describes the family aggregation of gyral morphology in the posterior perisylvian region in families that contain one or more children with a developmental language disorder. The probands in these families were 8 male and 2 female children referred through therapy programs and schools for children with language and reading problems. Family members included both biological parents (10 m, 10 f) and all available siblings (6 m, 4 f). Gyral morphology in the members of these families was… 
Reduced Cortical Folding in Mental Retardation
TLDR
The observed abnormal pattern of cortical gyrification revealed by significant reduction of lGI in multiple brain regions might reflect the developmental disturbance in intracortical organization and cortical connectivities in MR.
Individual differences in anatomy predict reading and oral language impairments in children.
TLDR
The results confirmed predictions that children with relatively smaller and symmetrical brain structures would have the severe comprehension impairments typical of SLI and rapid automatic naming was not predicted by the anatomical risk index, but by anatomical measures derived from the frontal lobes.
Brain mechanisms for reading and language processing in spina bifida meningomyelocele: a combined magnetic source- and structural magnetic resonance imaging study.
TLDR
A complex pattern of changes in cortical morphology and activation may serve as evidence for structural and functional brain reorganization ensuring preservation of language and decoding abilities in children with SBM.
The 7 NEUROBIOLOGY OF CHILD LANGUAGE DISORDERS
The scientific mapping between brain and language behavior is now proceeding at an exceptionally rapid pace. This venture, though, is far from new; it has deep roots planted in the early 19th century
Investigation of language and motor skills in Serbian speaking children with specific language impairment and in typically developing children.
TLDR
The results showed that the group of children with SLI had significantly more difficulties on the language and motor assessments compared to the control group, and Imitation of Complex Movements was the unique skill which reliably predicted expressive vocabulary in both typically developing children and inChildren with SLI.
Modularity and Developmental Disorders
In this chapter, we consider the origin of uneven cognitive profiles in individuals with developmental disorders, including accounts from cognitive, brain, and genetic levels of description. We begin
Language and reading abilities of children with autism spectrum disorders and specific language impairment and their first‐degree relatives
TLDR
The hypothesis that ALI and SLI families share similar genetic loading for language is not strongly supported, and it is suggested that the degree of overlap between these disorders and their broader phenotypes is smaller than previously thought.
Neurocognitive studies of language impairments: The bottom-up approach

Neurocognitive studies can approach gene-based developmental language impairments from two angles, which are complementary and ideally combined in a research program. One approach aims at an optimal

FMRI brain activation in a finnish family with specific language impairment compared with a normal control group.
TLDR
It is concluded that individuals with SLI showed reduced activation in brain areas that are critical for speech processing and phonological awareness.

Anomalous cerebral structure in dyslexia revealed with magnetic resonance imaging.
TLDR
Quantitative assessment of high-resolution magnetic resonance images can reveal functionally relevant variations and anomalies in cerebral structure that should improve the diagnosis, classification, and treatment of language disorders and other learning disabilities.
Developmental dyslexia: Four consecutive patients with cortical anomalies
TLDR
The neuroanatomical findings in 4 consecutively studied brains of men with developmental dyslexia are discussed with reference to developmental cortical anomalies, cerebral asymmetries, reorganization of the brain after early lesions, and the association between learning disorders, left handedness, and diseases of the immune system.
Brain morphology in developmental dyslexia and attention deficit disorder/hyperactivity.
TLDR
Although significantly more dyslexic children were left-handed than were the normal and ADD/H children, no significant relationship emerged between left- handedness, incidence of allergies or familial autoimmune disease, and variability in indexes of brain morphologic findings.

TLDR
Four families that include a specifically language-impaired (SLI) boy were studied to test the hypothesis that developmental language disorders are biologically transmittable and suggest that atypical perisylvian asymmetries reflect aTransmittable, biological factor that places some families at risk for language impairment.

TLDR
Three women with dyslexia are reported on, all of which showed to a variable extent brain warts, molecular layer ectopias, and focal architectonic dysplasia identical to those seen in the male cases.

TLDR
The data revealed that brothers and to a lesser degree sisters had a higher familial association with language impairment than did the parents, suggesting that the factors that contribute to developmental language disorders are at least in part associated with the family unit.
MRI findings in boys with specific language impairment
TLDR
Neuroanatomical findings suggest that a prenatal alteration of brain development underlies specific language impairment in children whose primary deficits were in language skills.
Familial aggregation in specific language impairment.
TLDR
Group data showed impairment rates estimated from the family-history questionnaires to be similar to the rates based on actual testing, and case-by-case analyses showed poor intrasubject agreement on classification as language impaired on the basis of current testing as compared to history information.
Cerebral hemispheric asymmetry in humans. Cortical speech zones in 100 adults and 100 infant brains.
TLDR
The findings suggest that a higher percentage of persons may have right-sided cerebral representation for speech than has been assumed previously and a predetermined morphological asymmetry contributes to establishing the ultimate pattern of cerebral speech representation following an early insult to a predisposed hemisphere.
Sulcus topography of the parietal opercular region: An anatomic and MR study
TLDR
The findings indicate that the Sylvian fissure is an unreliable landmark with respect to inferior parietal structures especially in left hemispheres, and individual mapping of perisylvian topography may contribute to studies on structural-functional relationship.
