蛾M. sexta由两类不同的中枢神经元组成：局部中间神经元，参与叶内的感觉处理;输出神经元，将感觉信息传递到大脑中的高级神经中枢的中继元件。每一类中不同类型的神经元都有许多共同的特征。所有的本地中间神经元有广泛的多球树突分支，缺乏明显的轴突，而所有的输出神经元有单球树突分支。触角叶的中央神经元也具有明显的两性异形。只有雄蛾对雌蛾的性信息素有反应。雄蛾触角叶中所有对信息素有反应的中枢神经元都有树突状分支，位于巨球复合体（macroglomerular complex）中，这是一个雄性特有的神经元区域。两种类型的信息素敏感的本地interneurons的形态学和生理学描述，而一个单一类型的输出神经元有一个树突状树枝状的巨球复合体。
The antennal lobes of the moth M. sexta are composed of 2 distinct classes of central neurons: local interneurons, involved in sensory processing within the lobe, and output neurons, the relay elements carrying sensory information to higher neuropil centers in the brain. The different types of neurons in each class share many characteristics. All of the local interneurons have extensive multiglomerular dendritic arborizations and lack distinct axons while all of the output neurons have uniglomerular dendritic arborizations. The central neurons of the antennal lobes also possess a distinct sexual dimorphism. Only the male moth responds to the female sex pheromone. All of the central neurons in the antennal lobe of the male moth that respond to pheromone have dendritic branches located in the macroglomerular complex, a male-specific neuropil region. Two types of pheromone-sensitive local interneurons are described morphologically and physiologically while a single type of output neuron has a dendritic arborization in the macroglomerular complex.
