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...

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.

Background:

Aphasia, a common post-stroke language disorder, has limited recovery with conventional therapy.
Current speech and language therapy show small effect sizes in chronic stroke patients.
Brain plasticity offers a potential target for enhancing aphasia rehabilitation.

Purpose of the Study:

To introduce and evaluate a novel brain-computer interface (BCI) based language training for aphasia.
To investigate the feasibility and efficacy of high-intensity BCI training in chronic aphasia.
To explore the neural mechanisms underlying BCI-induced language recovery.

Main Methods:

A BCI system recorded EEG signals during an auditory target word detection task.
Machine learning models provided real-time, brain-state-dependent feedback to patients.
A proof-of-concept study involved 10 chronic aphasia patients undergoing 30 hours of training.

Main Results:

High-intensity BCI training was feasible, even with rapid word presentation and challenging EEG signals.
Significant medium to large improvements were observed in multiple language assessments post-training.
Five patients transitioned from aphasic to non-aphasic status, indicating substantial recovery.

Conclusions:

BCI-based language training offers a promising new avenue for aphasia rehabilitation.
The training induced sustained language recovery without affecting attention or non-linguistic skills.
Neuroimaging suggests BCI training strengthens language networks and promotes neural rebalancing.
