The ultrastructure of nerve endings in the medial superior olive of the cat

Publisher’s permission requested and denied.The medial superior olive (MSO) is an important nucleus for the coding of sound localization and this requires a binaural interplay between excitation and inhibition. A variety of inhibitory effects have been demonstrated in the MS02 and post-stimulus time response patterns show that they can be quite complex. The present study has been undertaken to examine the nerve endings in the MSO to see whether a morphological basis for inhibition and excitation can be found, as this has been demonstrated in other areas of the brain
