Hearing

52.1K
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.

Auditory Perception01:17

Auditory Perception

337
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Auditory Pathway01:15

Auditory Pathway

5.4K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

The Cochlea01:13

The Cochlea

44.8K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

208
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...

Hair Cells01:22

Hair Cells

40.3K
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

Summary

Cochlear implant (CI) users showed more cognitive impairment, especially in executive functions, compared to normal-hearing individuals. Web-based cognitive tests like BrainCheck are useful for evaluating CI users' cognitive health.

Area of Science:

  • Neuroscience
  • Audiology
  • Cognitive Psychology

Background:

  • Cochlear implants (CI) are vital for severe-to-profound hearing loss.
  • Cognitive function in CI users requires further investigation.
  • Subjective hearing perception may correlate with cognitive abilities.

Purpose of the Study:

  • To assess cognitive function in cochlear implant users.
  • To compare CI users' cognitive performance with normal-hearing controls.
  • To explore the relationship between cognitive function and self-reported hearing in CI users.

Main Methods:

  • Utilized the web-based BrainCheck platform for cognitive assessment.
  • Included 42 cochlear implant users and normal-hearing controls (young and older).
  • Administered tests including Trail Making A/B, Stroop, and digit symbol substitution.

Main Results:

  • CI users demonstrated poorer cognitive function than controls across most tasks.
  • Executive function domains showed the highest rates of possible/likely cognitive impairment in CI users.
  • A trend suggested a link between composite cognitive scores and subjective hearing.

Conclusions:

  • Cochlear implant users are at higher risk for executive function impairment.
  • BrainCheck offers a practical method for cognitive self-assessment in CI populations.
  • Early detection of cognitive decline can inform CI management and support.
