| Research Abstract |
We analyzed how to calculate the interaural time difference that is one of the important key for the sound localization. The interaural time difference is calculated by the bilateral projection from the nucleus magnocellularis that is inhibited by the superior olivary nucleus. We studied using in vivo recording and some drugs and found that the superior nucleus sharpens the sound frequency response in the magnocellularis. We also found that the mutual inhibition between superior nucleus balance the activity bilateral nucleus magnocellularis. These findings are considered to be important for the calculation of the sound localization.
