The hair cell transmitter depolarizes the afferent neuron. The greater the degree of depolarization, the greater frequency of action potentials in the afferent neuron, which therefore codes for the intensity of the sound.

The afferent neurons of the auditory nerve terminate in the cochlear nuclei in the brainstem. From here, the auditory pathway can be complex. The simplified figure below , shows secondary neurons passing through the auditory reflex centers of the inferior colliculi and synapsing with third-order neurons that travel to a nucleus of the thalamus called the medial geniculate body.

In the medial geniculate body, the third-order neurons form synapses with quaternary neurons that transmit information to the auditory cortex in the temporal lobe, resulting in the conscious recognition of sound.

To simplify the auditory pathway: 1. These fibers then terminate in the cochlear nucleus and synapse with secondary neurons that ascend to the inferior colliculus. Tertiary neurons extend to the thalamus and synapse with 4.

Note that the overall path length of the auditory pathway is relatively short because the inner ear is proximal to the temporal lobe of the brain, and relatively little additional cortical processing is required for the conscious recognition of auditory stimulus short pathway, few synapses.

In this laboratory, we will examine the reaction times for auditory and visual responses to stimulus. The reaction time is simply the time required for processing between a visual or auditory stimulus and a response. We can compare this information to our anatomy knowledge of the number of synapses in a pathway, and the path length, to determine what type of information is processed faster by the human body.

Reaction time measurements will be taken from an individual subjected to harmless visual and sound stimuli. In addition, the effect of priming and prediction may be examined. It is best to use a one or two word cue directly before clicking the event marker button.

Aim : To measure the reaction time of a subject to auditory cues delivered at a predictable interval. Skip to content The nervous system allows us to detect changes in the environment and react to them. Figure 1. The mean visual reaction time is The mean auditory reaction time is Conclusion: This shows that the auditory reaction time is faster than the visual reaction time.

And also males have faster reaction times when compared to females for both auditory as well as visual stimuli. Pain MT, Hibbs A. Sprint starts and the minimum auditory reaction time. J Sports Sci.
