In neuronal activity recorded from human middle temporal gyrus during learning of associations between word pairs, a population was identified that had greater activity for associations that were learned rapidly during initial encoding compared to those learned slowly or not at all by an individual subject. This population can be separated from other neurons by the combination of inhibition during word reading when no learning is required and excitation during recent memory for words. These neurons are present in both hemispheres, predominately in deeper layers of cortex. During initial encoding, the increased activity appears at presentation of all word pairs but persists for several seconds only for the rapidly learned pairs, likely reflecting rehersal of items being learned. Human associative learning is related to activity of this specific population of "association" neurons, identified here for the first time.
在学习单词对之间的关联过程中，从人类颞中回记录到的神经元活动中，识别出了一个神经元群体。与个体受试者学习缓慢或根本未学习的关联相比，该群体对在初始编码期间快速学习的关联具有更强的活动。当不需要学习时，该群体可通过单词阅读期间的抑制和单词近期记忆期间的兴奋相结合的方式与其他神经元区分开来。这些神经元存在于两个半球，主要位于皮质的较深层。在初始编码期间，所有单词对出现时都会出现活动增加，但仅对快速学习的单词对持续数秒，这可能反映了正在学习的项目的复述。人类联想学习与首次在此确定的这种特定“关联”神经元群体的活动有关。
