Higher Mental Functions of the Brain: Language

Higher 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...

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...

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...

Lateralization

Lateralization

Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Language and Cognition

Language 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.

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Summary

Morphemes possess distinct neural memory traces in Arabic, differing by function. This study provides evidence for specific brain mechanisms supporting morphological processing in language.

Area of Science:

Neuroscience
Linguistics
Cognitive Science

Background:

Two views exist on morphology: a distinct cognitive domain or a byproduct of form-meaning correlations.
The neural basis of morphological processing remains debated, with differing predictions for brain involvement.

Purpose of the Study:

To investigate whether morphemes in Arabic have specific neural representations.
To examine if these representations differ based on morpheme function.

Main Methods:

A mismatch negativity (MMN) study was conducted using Arabic stimuli.
MMN responses were analyzed for abstract consonantal roots and abstract vocalic word patterns.

Main Results:

Abstract consonantal roots elicited an early MMN (160 ms), with a symmetric fronto-central distribution.
Abstract vocalic word patterns elicited a later MMN (250 ms), lateralizing to the left peri-sylvian areas.

Conclusions:

Morphemes in Arabic show distinct memory traces correlated with their functional properties.
Evidence supports a specific neuronal basis for morphological processing within the brain's language network.
