Explain how the brain codes for the spatial location of sound
What will be an ideal response?
Answer: Auditory neurons are sensitive to the differences in the arrival times of an auditory stimulus (low frequency). A sound that occurs directly in front will arrive at the left and right ears at the same time; a sound that occurs to the left will arrive at the left ear sooner than at the right ear. High frequency sounds may be detected using differences in sound intensity.
