为了探索昆虫大脑结构可塑性的起源和可能的行为后果，我们利用了以下几点：（1）初级触角感觉中枢的高度分隔性（2）触角叶神经元内的单个隔室或肾小球可以被识别的容易程度，和（3）成年工蜂触角叶中易于识别的肾小球变化的可预测性。用保幼激素类似物甲氧普烯和蜂巢操作技术处理，以诱导年轻工蜂的早熟觅食行为。这些治疗对嗅觉学习性能的个体发育的影响和容易识别的肾小球在触角叶的蜜蜂大脑的体积平行检查。研究表明：（1）肾小球体积的显著变化是活动依赖性的;（2）对花香的联想学习随着经验的增加而提高。联想学习性能的改善与肾小球体积的增加在时间上一致。这就提出了一个重要的问题：由行为变化引起的肾小球体积变化仅仅是外周感觉通路使用变化的结果，还是与学习和长期记忆形成的基础事件有关？
To explore the origins and possible behavioral consequences of structural plasticity in an insect brain, we have taken advantage of the following: (1) the highly compartmentalized nature of the primary antenno-sensory centers (antennal lobes) of the brain, (2) the ease with which individual compartments, or glomeruli, within the antennal-lobe neuropil can be identified, and (3) the predictability of changes to readily identifiable glomeruli in the antennal lobes of the adult worker honey bee. Treatment with the juvenile hormone analog methoprene and hive manipulation techniques are used to induce precocious foraging behavior in young worker honey bees. The impact of these treatments on the ontogeny of olfactory learning performance and on the volumes of readily identifiable glomeruli in the antennal lobes of the bee brain are examined in parallel. The study reveals that (1) significant changes in glomerular volume are activity dependent and (2) associative learning of floral odors improves with experience. Improvements in associative learning performance coincide temporally with increases in glomerular volume. This raises an important question: are changes in glomerular volume that result from shifts in behavior simply a consequence of changes in the use of peripheral sensory pathways, or are they associated with events that underlie learning and the formation of long-term memories?
