  2. Auditory exclusion - Wikipedia

    en.wikipedia.org/wiki/Auditory_exclusion

    During this “Fight or flight” /acute stress response, both areas of the conscious brain can struggle to process this information at the same time. Consequently, perceptual distortions can occur (e.g. slow motion/ tunnel vision, disruption of hearing) As a part of this, the processing of auditory information can be stopped completely ...

  3. Neural encoding of sound - Wikipedia

    en.wikipedia.org/wiki/Neural_encoding_of_sound

    The neural encoding of sound is the representation of auditory sensation and perception in the nervous system. [1] The complexities of contemporary neuroscience are continually redefined. Thus what is known of the auditory system has been continually changing.

  4. Mental chronometry - Wikipedia

    en.wikipedia.org/wiki/Mental_chronometry

    Simple reaction time is the motion required for an observer to respond to the presence of a stimulus. For example, a subject might be asked to press a button as soon as a light or sound appears. Mean RT for college-age individuals is about 160 milliseconds to detect an auditory stimulus, and approximately 190 milliseconds to detect visual stimulus.

  5. Startle response - Wikipedia

    en.wikipedia.org/wiki/Startle_response

    In animals, including humans, the startle response is a largely unconscious defensive response to sudden or threatening stimuli, such as sudden noise or sharp movement, and is associated with negative affect. [1] Usually the onset of the startle response is a startle reflex reaction.

  6. Neural coding - Wikipedia

    en.wikipedia.org/wiki/Neural_coding

    Neural coding (or neural representation) is a neuroscience field concerned with characterising the hypothetical relationship between the stimulus and the neuronal responses, and the relationship among the electrical activities of the neurons in the ensemble.

  8. Neuronal noise - Wikipedia

    en.wikipedia.org/wiki/Neuronal_noise

    Neuronal activity at the microscopic level has a stochastic character, with atomic collisions and agitation, that may be termed "noise." [4] While it isn't clear on what theoretical basis neuronal responses involved in perceptual processes can be segregated into a "neuronal noise" versus a "signal" component, and how such a proposed dichotomy could be corroborated empirically, a number of ...
