Description:
Neurons in the lateral belt areas of rhesus monkey auditory cortex prefer complex sounds to pure tones, but functional specializations of these multiple maps in the superior temporal region have not been determined. We tested the specificity of neurons in the lateral belt with species-specific communication calls presented at different azimuth positions. We found that neurons in the anterior belt are more selective for the type of call, whereas neurons in the caudal belt consistently show the greatest spatial selectivity. These results suggest that cortical processing of auditory spatial and pattern information is performed in specialized streams rather than one homogeneously distributed system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tian, B -- Reser, D -- Durham, A -- Kustov, A -- Rauschecker, J P -- R01-DC03489/DC/NIDCD NIH HHS/ -- R03-DC03845/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2001 Apr 13;292(5515):290-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Georgetown Institute for Cognitive and Computational Sciences, Department of Physiology and Biophysics, Georgetown University Medical Center, Washington, DC 20007, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11303104" target="_blank"〉PubMed〈/a〉
