Question
The auditory pathway from the cochlea to the cerebral cortex of the brain (where hearing is conscioushy perceived and interpreted) is complex. It includes decussation ("crossing over", where axons cross from one side of the brain to the other) and multiple nuclei (points of synapse with other neurons) along the way. Midbran Cor of t Braan stem Questions #3 a. What do you think the value is of having decussation in the auditory pathway? b. What do you think the value is of having multiple points of synapsing along the auditory pathway? Speculate about the symptoms that you think would come from having damage to the right inferior colliculus c.Explanation / Answer
a. It is that neural decussation advances hemispheric cross-talk while keeping CNS development from entering way towards a 'split cerebrum' sensory system… hybrid keeps the mind from going into disrepair! Point: if the ears and eyes had projections that at last synapsed onto the closest bit of cortex, there wouldn't be numerous intersection filaments to stick these cerebrum areas together.
b. In the reticular pathway of the brainstem and the mesencephalus, a few synapses happen. It's here that the sound-related data is incorporated with the various tangible modalities to be 'triaged' into which has the most noteworthy need at any given minute.
c. The elements of the inferior colliculus, yet now plainly the structure is an essential segment of the sound-related pathway. It is associated with adjusting and incorporating sound-related sensations from an assortment of other sound-related districts, and sending that data on to the thalamus and cerebral cortex. It additionally is critical to recognizing the area of sound in space and situating the body towards such sounds. Hence damage to this will disturb the signaling.
