Higher Mental Functions of the Brain: Language01:10

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...
Brain Imaging01:14

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
Language and Cognition01:27

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.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Neuromodulation

Background:

  • Anodal transcranial direct current stimulation (tDCS) is established for improving motor learning.
  • Associative verbal learning is vital for new language acquisition and post-stroke aphasia rehabilitation.

Purpose of the Study:

  • To investigate the efficacy of anodal tDCS in enhancing associative verbal learning.
  • To assess tDCS's potential for improving language acquisition in healthy adults and language reacquisition in aphasia patients.

Main Methods:

  • Nineteen healthy, right-handed young adults participated in a randomized, double-blind, sham-controlled study.
  • Participants underwent anodal tDCS, cathodal tDCS, or sham stimulation over the left peri-sylvian area.
  • A miniature lexicon of 30 novel object names was used to measure learning speed, success, and native language transfer.

Main Results:

  • Anodal tDCS significantly improved associative learning speed and success compared to sham stimulation.
  • No significant differences were observed in mood, reaction times, or response styles across stimulation conditions.

Conclusions:

  • Anodal tDCS is a promising non-invasive brain stimulation technique for enhancing verbal learning in healthy adults.
  • The findings suggest potential therapeutic applications of tDCS for improving language recovery after stroke-induced aphasia.
