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...

Hierarchy of Motor Control

Hierarchy of Motor Control

The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Cerebral Hemispheres

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Direct Motor Pathways

Direct Motor Pathways

The direct motor pathways, also known as the pyramidal tracts, are a group of neural pathways that originate in the brain and descend through the spinal cord. They control the voluntary movement of the body. There are two major direct motor pathways: the corticospinal and the corticobulbar tracts.
The corticospinal tract is responsible for the voluntary movement of the limbs and trunk. It originates in the cerebral cortex of the brain and descends through the cerebrum's internal capsule and the...

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.

Organization of the Nervous System

Organization of the Nervous System

The nervous system is one of the most complex systems in our body. It is organized into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS, comprising the brain and spinal cord, houses billions of neurons. The brain is housed in the skull, while the spinal cord is linked to the brain through the foramen magnum of the occipital bone and is surrounded by the protective structure of the vertebral column. It is responsible for processing various...

Summary

Central and peripheral writing processes interact during word production. Lexical and sublexical variables influence movement execution, suggesting a cascaded effect in spelling.

Background:

Previous research on word production has often separated central (cognitive) and peripheral (motor) processes.
This separation has limited our understanding of how these systems interact during written output.

Purpose of the Study:

To investigate the interaction between central and peripheral processes in word production.
To provide evidence for the influence of lexical and sublexical variables on motor execution during writing.

Main Methods:

French participants wrote regular words, irregular words, and pseudo-words using a digitizer.
Analysis focused on response latencies and individual letter durations during the writing task.

Main Results:

Pseudo-words resulted in longer overall response latencies compared to regular words.
Letter durations varied based on word type (regular, irregular, pseudo-word) and letter position.
Irregular words showed longer letter durations than regular words, modulated by irregularity position.

Conclusions:

Movement production in writing is significantly affected by central lexical and sublexical processing.
Central processing is not fully completed before motor initiation, influencing peripheral writing mechanisms in a cascaded manner.
The extent of this cascade differs between lexical and sublexical processing levels.
