Structural and functional asymmetries of the temporal lobe affect language development and may also play a role in a variety of disorders, ranging from specific language impairment to schizophrenia. Whole-head neuromagnetometers allow the noninvasive measurement of functional asymmetries since activity from both hemispheres is recorded simultaneously. In the present study, the location of the auditory cortices and their responsiveness to pure tones was compared between hemispheres in healthy human subjects. Data suggest a greater contralateral than ipsilateral activation. In line with previous findings, sources of responses for the right hemisphere seem to be more anterior than for the left one.
颞叶的结构和功能不对称会影响语言发展，并且可能在从特定语言障碍到精神分裂症等多种疾病中发挥作用。全头式神经磁强计能够进行无创测量功能不对称性，因为它可以同时记录来自两个半球的活动。在本研究中，对健康人类受试者两半球之间听觉皮层的位置及其对纯音的反应性进行了比较。数据表明对侧激活大于同侧激活。与先前的研究结果一致，右半球反应源似乎比左半球更靠前。
