Hearing01:31

Hearing

58.1K
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.

The Cochlea01:13

The Cochlea

52.0K
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.

Hair Cells01:22

Hair Cells

45.9K
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.

Contact-dependent Signaling01:19

Contact-dependent Signaling

48.2K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

In animal cells, gap junctions are formed...

    Area of Science:

    • Sociology of Science
    • Disability Studies
    • Linguistic Anthropology

    Background:

    • Deaf individuals are often perceived by the hearing society as impaired, a view challenged by a growing number of Deaf and hearing researchers.
    • This perspective shifts the focus from a deficit model to recognizing Deaf experiences and knowledge systems.

    Purpose of the Study:

    • To examine the essential components for successful research partnerships between Deaf and hearing researchers.
    • To propose the adoption of a Deaf epistemology as a foundational element for these collaborations.

    Main Methods:

    • Qualitative analysis of perceptions regarding effective Deaf/hearing research partnerships.
    • Exploration of necessary frameworks and principles for equitable collaboration.

    Main Results:

    • Equity is identified as a core category for successful research teams.
    • Mutual understanding of American Sign Language (ASL) as the lingua franca is crucial for seamless communication and access.
    • A transformative research paradigm is necessary to ensure an equitable environment for Deaf researchers.

    Conclusions:

    • Successful Deaf/hearing research partnerships require a foundation of equity and mutual respect.
    • Embracing a Deaf epistemology and prioritizing ASL as the communication standard are vital for inclusive and effective research.
    • A transformative approach is essential to dismantle existing power imbalances and promote true collaboration.
