Summary
Genetic and environmental factors influence language disorders. This review highlights gene variants and regulatory networks crucial for neural development, revealing language
Area of Science:
- Neuroscience
- Genetics
- Linguistics
Background:
- Language disorders present diverse phenotypes with complex genetic and environmental causes.
- Recent genetic studies have illuminated molecular and cognitive mechanisms underlying language.
- Understanding the biological basis of language is crucial for addressing related disorders.
Purpose of the Study:
- To review the functional aspects of gene variants associated with speech and language disorders.
- To examine candidate genes implicated in heritable speech and language impairments.
- To evaluate language phenotypes and genetic factors in developmental syndromes affecting language.
Main Methods:
- Literature review of genetic associations with speech and language phenotypes.
- Analysis of allelic variants in genes impacting normal and disordered language.
- Examination of genetic components within developmental syndromes with language alterations.
Main Results:
- Predominance of regulatory networks controlling neuronal differentiation and function.
- Identification of gene networks involved in neural connections essential for cognition and language.
- Highlighting multifactorial genetic and environmental determinants in overlapping speech and language phenotypes.
Conclusions:
- Language faculty is closely linked with cognitive functions, suggesting an interconnected developmental network.
- Genetic elements play a significant role in the development and function of language.
- Findings offer insights into the genetic contribution and modular nature of language.

01:10Higher Mental Functions of the Brain: Language
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:24Components of Language
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs. “eh”). Phonemes combine to...
01:16Language
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

01:25Introduction to Language of Pathophysiology l
Pathophysiology investigates how biological mechanisms—typically starting at the cellular level—disrupt normal bodily functions. It bridges anatomy and physiology to explain the progression of disease. With this foundation, it is important to understand the following key terms used to describe disease processes: Diagnosis:The process of identifying a disease using clinical evaluation, including signs (objective evidence like rashes), symptoms (subjective experiences like pain), laboratory test...
