Language

Language

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.
Corballis and Suddendorf (2007) and Tomasello and Rakoczy (2003) highlight the role of language in...

Language Development

Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Components of Language

Components 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...

Gene Families

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Summary

The FOXP2 gene, crucial for speech and language, is preferentially expressed in the developing striatum. This suggests the striatum plays a key role in the neural processing of language.

Area of Science:

Neuroscience
Molecular Genetics
Developmental Biology

Context:

The human genome contains genes influencing speech and language acquisition.
The FOXP2 gene is the first identified 'language gene', with disruptions causing severe speech and language disorders.

Purpose:

To investigate the anatomical basis of language processing in the brain.
To examine the developmental expression patterns of FOXP2/Foxp2 genes in monkey and rat brains.

Summary:

FOXP2/Foxp2 gene expression was studied in developing monkey and rat brains.
Preferential expression of FOXP2/Foxp2 was observed in the striosomal compartment of the developing striatum.
The striatum, particularly its striosomal system, is implicated in neural information processing for speech and language.

Impact:

Suggests a novel role for the striatum in language and speech processing.
Aligns with the declarative/procedural model of language, linking procedural memory to basal ganglia and frontal cortex.
Provides a foundation for further research into the genetic and neural underpinnings of human language capacity.
