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...
Larynx01:21

Larynx

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Hearing01:31

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
Components of Language01:24

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...
Perception of Sound Waves01:01

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...
Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...

Summary

Deaf individuals can produce intelligible speech using somatosensory feedback, not auditory feedback. This research reveals how the brain prioritizes action-based sensory information for vocalization.

Area of Science:

  • Neuroscience
  • Speech Science
  • Auditory Neuroscience

Background:

  • Auditory feedback is crucial for typical vocal production and speech intelligibility.
  • The mechanisms enabling speech production in deaf individuals remain incompletely understood.
  • Sensory representations in the brain are often considered action-oriented.

Purpose of the Study:

  • To investigate the role of somatosensory feedback in speech production for deaf individuals.
  • To explore the brain's processing of sensory information for vocalization.
  • To provide insights into the action-oriented nature of sensory representations.

Main Methods:

  • Utilized a study focusing on deaf individuals' speech production capabilities.
  • Analyzed the reliance on non-auditory sensory feedback pathways.

  • Examined neural correlates of vocal control and sensory integration.

    • Main Results:

    • Somatosensory feedback significantly contributes to intelligible speech production in deaf individuals.
    • This finding challenges the exclusive reliance on auditory feedback models.
    • Evidence supports the hypothesis that sensory systems are organized around action goals.

    Conclusions:

    • Somatosensory feedback is a viable alternative for achieving speech intelligibility in the absence of hearing.
    • The brain's sensory representations are fundamentally linked to motor actions.
    • This study advances our understanding of neural plasticity and sensory substitution in speech.
