我们确定了人类外侧和基底颞叶皮层的功能解剖分区，这些分区与物体名称、文本和听觉单词的近期言语记忆有关。细胞外神经元活动记录在记忆编码识别相比，在编码，存储或回忆检索阶段的记忆任务，在识别记忆，和内隐记忆过程中重复启动测量。在编码过程中的活动频率的变化记录从大多数神经元。在外侧颞叶皮层，优势半球的编码变化更可能是多模态的，而非优势半球的编码变化是单峰的。随着记忆其他方面的变化，神经元大量分离，定义了额外的细分。下外侧皮层和基底皮层与记忆阶段有关，上后外侧皮层与内隐记忆和再认记忆有关。
We identified functional anatomical subdivisions of human lateral and basal temporal cortex related to recent verbal memory for object names, text and auditory words. Extracellular neuronal activity was recorded during memory encoding compared to identification, during encoding, storage or recall retrieval stages of the memory task, during recognition memory, and during implicit memory as measured by repetition priming. Changes in frequency of activity during encoding were recorded from most neurons. In lateral temporal cortex, these encoding changes in the dominant hemisphere were more likely to be polymodal, whereas those in nondominant hemisphere were unimodal. There was substantial separation of neurons with changes in other aspects of memory, defining additional subdivisions. Inferior lateral and basal cortex were related to memory stages, and superior-posterior lateral cortex was related to implicit and recognition memory.
