Abstract:	摘要： AbstractFrequency modulation (FM) is an acoustic feature of nearly all complex sounds. Directional FM sweeps are especially pervasive in speech, music, animal vocalizations, and other natural sounds. Although the existence of FM-selective cells in the auditory cortex of animals has been documented, evidence in humans remains equivocal. Here we used multivariate pattern analysis to identify cortical selectivity for direction of a multitone FM sweep. This method distinguishes one pattern of neural activity from another within the same ROI, even when overall level of activity is similar, allowing for direct identification of FM-specialized networks. Standard contrast analysis showed that despite robust activity in auditory cortex, no clusters of activity were associated with up versus down sweeps. Multivariate pattern analysis classification, however, identified two brain regions as selective for FM direction, the right primary auditory cortex on the supratemporal plane and the left anterior region of the superior temporal gyrus. These findings are the first to directly demonstrate existence of FM direction selectivity in the human auditory cortex. 其他題名： J Cogn Neurosci 出版者： One Rogers Street, Cambridge, MA 02142-1209, USA: MIT Press - Journals 出版日期： 2012-09-01 出處： Journal of Cognitive Neuroscience, 2012-09, Vol.24 (9), p.1896-1907 資源來源： EBSCOhost Academic Search Premier 版權： Copyright MIT Press Journals Sep 2012 識別號： ISSN: 0898-929X 識別號： ISSN: 1530-8898 識別號： EISSN: 1530-8898 識別號： DOI: 10.1162/jocn_a_00254 識別號： PMID: 22640390
