  2. Auditory cortex - Wikipedia

    en.wikipedia.org/wiki/Auditory_cortex

    The auditory cortex takes part in the spectrotemporal, meaning involving time and frequency, analysis of the inputs passed on from the ear. The cortex then filters and passes on the information to the dual stream of speech processing. [5] The auditory cortex's function may help explain why particular brain damage leads to particular outcomes.

  3. Mind machine - Wikipedia

    en.wikipedia.org/wiki/Mind_machine

    Enterprises started to produce different types of mind machines and some scientists followed the line of research to explore if and how these devices elicit effects on brain processes. [ 8 ] In the late 1980s and early 1990s Farley initiated an investigation concerning medical claims made by some manufacturers and sellers. [ 9 ]

  4. Audio-visual entrainment - Wikipedia

    en.wikipedia.org/wiki/Audio-Visual_Entrainment

    Audio-visual entrainment (AVE), a subset of brainwave entrainment, uses flashes of lights and pulses of tones to guide the brain into various states of brainwave activity. AVE devices are often termed light and sound machines or mind machines. Altering brainwave activity is believed to aid in the treatment of psychological and physiological ...

  5. 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.

  6. Auditory system - Wikipedia

    en.wikipedia.org/wiki/Auditory_system

    The folds of cartilage surrounding the ear canal are called the auricle. Sound waves are reflected and attenuated when they hit the auricle, and these changes provide additional information that will help the brain determine the sound direction. The sound waves enter the auditory canal, a deceptively simple tube.

  7. Speech science - Wikipedia

    en.wikipedia.org/wiki/Speech_science

    The production of speech is a highly complex motor task that involves approximately 100 orofacial, laryngeal, pharyngeal, and respiratory muscles. [2] [3] Precise and expeditious timing of these muscles is essential for the production of temporally complex speech sounds, which are characterized by transitions as short as 10 ms between frequency bands [4] and an average speaking rate of ...

  8. Auditosensory cortex - Wikipedia

    en.wikipedia.org/wiki/Auditosensory_cortex

    Furthermore, the auditory impulse is recognised, organised and interpreted as sensory information. The different properties of sound waves are necessary to help the comprehension of language and sound. The language competence directly correlates with the ability of auditosensory cortex in terms of strength and frequency of neuronal activity.

  9. Binaural fusion - Wikipedia

    en.wikipedia.org/wiki/Binaural_fusion

    The cells of lower auditory pathways are specialized to analyze physical sound parameters. [3] Summation is observed when the loudness of a sound from one stimulus is perceived as having been doubled when heard by both ears instead of only one. This process of summation is called binaural summation and is the result of different acoustics at ...
