why in acoustic neuroma intra aural latency is present as both pathway are interconnected?
Interaural latency of wave V is measured separately in each ear by giving sound in both ears separately and then seeing the time it takes for wave V to be recorded in that particular ear.
Both auditory pathways are interconnected, but sound reaches the auditory pathway in which the sound is given earlier than the other ear leading to the localisation of sound .
If sound is given in each ears separately, the latency of wave V should be same . If there is any tumour in the pathway it will delay the transmission in that pathway and increase the latency in that ear as compared to the normal side .
