用正电子发射计算机断层扫描(PET)测量了单音和元音基本歌唱时的脑血流量(CBF)，并与被动听复杂音调进行了比较。与运动控制相关的皮质区域的CBF增加见于辅助运动区、扣带前皮质、中央前回、岛前(和中央前盖的相邻内面)和小脑，复制了以前在言语中看到的最多。听觉皮质的增加见于右侧Heschl回和后上颞叶平面(以及紧靠其上的顶叶皮质)。由于近右侧的Heschl‘s皮层与复杂的音调知觉有关，它在这里的不对称激活可能与分析自己声音的基频以进行反馈引导调制有关。
Cerebral blood flow (CBF) was measured with PET during rudimentary singing of a single pitch and vowel, contrasted to passive listening to complex tones. CBF increases in cortical areas related to motor control were seen in the supplementary motor area, anterior cingulate cortex, precentral gyri, anterior insula (and the adjacent inner face of the precentral operculum) and cerebellum, replicating most previously seen during speech. Increases in auditory cortex were seen within right Heschl's gyrus, and in the posterior superior temporal plane (and the immediately overlying parietal cortex). Since cortex near right Heschl's has been linked to complex pitch perception, its asymmetric activation here may be related to analyzing the fundamental frequency of one's own voice for feedback-guided modulation.
