Localization and morphology of neuronal groups in the ventrobasal thalamic complex that project to the vibrissae area in the somatosensory rat cortex were studied by means of retrograde axonal transport of horseradish peroxidase (HRP). The HRP-labelled cells were located in the ventroposterolateral nucleus of the ventrobasal complex and were grouped in "barreloids" 100-120 microns wide. Staining of several "barreloids" even when the injection was made in a restricted area of the cortex and the growth of labelled cells number in each "barreloid" with an increase in the injection area suggested the existence of divergence as well as convergence of thalamocortical specific connections. Various forms of relay neurons and different extent of HRP-granule inclusion may reflect their different functional value in thalamocortical relationship.
通过辣根过氧化物酶（HRP）逆行轴突运输法，研究了大鼠体感皮层中投射至触须区的丘脑腹侧基底复合体中神经元群的定位和形态。HRP标记的细胞位于腹侧基底复合体的腹后外侧核，聚集成宽100 - 120微米的“桶状小体”。即使将注射部位限定在皮层的一个受限区域，几个“桶状小体”仍会被染色，并且随着注射区域的增大，每个“桶状小体”中标记细胞数量的增加表明丘脑皮质特异性连接存在发散和汇聚现象。各种形式的中继神经元以及HRP颗粒包含程度的不同可能反映了它们在丘脑皮质关系中的不同功能价值。
