Input neurons (INs) in the calyces of the mushroom bodies (MBs) of the cockroach brain were examined by single- or multiple-staining with cobalt lysine and by Golgi impregnation. Olfactory INs had axon terminals with tuft-like, button-like or spiny-blebbed arbors in specific concentric zones in calycal neuropil. INs which responded to light stimulation had thick brush-like arbors along with axonal branches extending radially along the inner layer of calycal neuropil. Some of multiglomerular INs and two types of protocerebral INs extended blebbed axonal branches to the outer surface layer of calycal neuropil or thick bush-like axonal branches with many varicosities to entire calycal neuropil. The distribution patterns of dendrites and axon terminals of INs in the calyces suggest the existence of functional subdivisions in calycal neuropil.
通过赖氨酸钴单染色或多重染色以及高尔基浸染法，对蟑螂脑蘑菇体花萼中的输入神经元（INs）进行了检查。嗅觉输入神经元在花萼神经纤维网的特定同心区域具有簇状、纽扣状或棘状泡状的轴突终末。对光刺激有反应的输入神经元具有浓密的刷状分支，以及沿花萼神经纤维网内层呈放射状延伸的轴突分支。一些多小球输入神经元和两种原脑输入神经元将泡状轴突分支延伸至花萼神经纤维网的外表面层，或将具有许多膨体的浓密灌木状轴突分支延伸至整个花萼神经纤维网。花萼中输入神经元的树突和轴突终末的分布模式表明花萼神经纤维网中存在功能细分。
