Description:
The mustache bat emits a three-harmonic echolocation pulse. At the external ear, large interaural intensity differences are generated only when a sound originates within a limited area of two-dimensional space, and this area is different for each pulse harmonic. As a consequence, the external ear generates pronounced binaural spectral cues containing two-dimensional spatial information. This information is encoded in the inferior colliculus by neurons tuned to one of the harmonics and sensitive to interaural intensity differences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fuzessery, Z M -- Pollak, G D -- NS 13276/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 17;225(4663):725-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6463649" target="_blank"〉PubMed〈/a〉
