传统的梯度回波磁共振成像（MRI）在4特斯拉成功地用于研究活动的布洛卡区在内部语音字生成健康的右利手志愿者。在所有受试者中，外侧沟升支周围的内部灰质都表现出活动，深至布洛卡区的皮质表面代表。这些研究证明了功能性MRI能够非侵入性地映射语言相关的认知功能。这种功能定位对基础神经科学研究和神经外科规划都有价值。
CONVENTIONAL gradient-echo magnetic resonance imaging (MRI) at 4 Tesla was used successfully to study the activity of Broca's area during internal speech word generation in healthy right-handed volunteers. Activity was demonstrated in the internal gray matter surrounding the ascending ramus of the lateral sulcus, deep to the cortical surface representation of Broca's area, in all the subjects. These studies demonstrate the capability of functional MRI to non-invasively map language related cognitive functions. Such functional mapping has value for both the study of basic neuroscience and neurosurgical planning.
