  2. Neural encoding of sound - Wikipedia

    en.wikipedia.org/wiki/Neural_encoding_of_sound

    The frequency of a sound is defined as the number of repetitions of its waveform per second, and is measured in hertz; frequency is inversely proportional to wavelength (in a medium of uniform propagation velocity, such as sound in air). The wavelength of a sound is the distance between any two consecutive matching points on the waveform.

  3. Auditosensory cortex - Wikipedia

    en.wikipedia.org/wiki/Auditosensory_cortex

    Heschl found a cortical structure that appeared differently from most of the temporal lobe. The distinct structure occupied Brodmann area 42 and was later named the transverse temporal gyri of Heschl. [4] The discovery provided insight into the anatomical network within the primary cortex. It is the first site to process incoming sound information.

  4. Auditory cortex - Wikipedia

    en.wikipedia.org/wiki/Auditory_cortex

    Damage to the auditory cortex in humans leads to a loss of any awareness of sound, but an ability to react reflexively to sounds remains as there is a great deal of subcortical processing in the auditory brainstem and midbrain. [13] [14] [15] Neurons in the auditory cortex are organized according to the frequency of sound to which they respond ...

  5. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    Sound is propagated by progressive longitudinal vibratory disturbances (sound waves)." [ 17 ] This means that the correct response to the question: " if a tree falls in a forest and no one is around to hear it, does it make a sound? " is "yes", and "no", dependent on whether being answered using the physical, or the psychophysical definition ...

  6. Cochlea - Wikipedia

    en.wikipedia.org/wiki/Cochlea

    For one, the tall hair cell is very similar in function to that of the inner hair cell, and the short hair cell, lacking afferent auditory-nerve fiber innervation, resembles the outer hair cell. One unavoidable difference, however, is that while all hair cells are attached to a tectorial membrane in birds, only the outer hair cells are attached ...

  7. Transverse temporal gyrus - Wikipedia

    en.wikipedia.org/wiki/Transverse_temporal_gyrus

    The transverse temporal gyrus, also called Heschl's gyrus (/ ˈ h ɛ ʃ əl z ˈ dʒ aɪ r aɪ /) or Heschl's convolutions, is a gyrus found in the area of each primary auditory cortex buried within the lateral sulcus of the human brain, occupying Brodmann areas 41 and 42.

  8. Organ of Corti - Wikipedia

    en.wikipedia.org/wiki/Organ_of_Corti

    Cross-section through the spiral organ of Corti at greater magnification, showing position of the hair cells on the basement membrane. The organ of Corti is located in the scala media of the cochlea of the inner ear between the vestibular duct and the tympanic duct and is composed of mechanosensory cells, known as hair cells. [2]

  9. Spiral ganglion - Wikipedia

    en.wikipedia.org/wiki/Spiral_ganglion

    The spiral (cochlear) ganglion is a group of neuron cell bodies in the modiolus, the conical central axis of the cochlea. These bipolar neurons innervate the hair cells of the organ of Corti . They project their axons to the ventral and dorsal cochlear nuclei as the cochlear nerve , a branch of the vestibulocochlear nerve (CN VIII).
