The anatomy, cytoarchitectonics and unit responses of the vibrissal barrel field make it a good subject for studying the central effects of peripheral receptor manipulations. The paper reviews the properties of the barrel system and the evidence for columnar functioning of the barrel cortex. The plastic changes of the single vibrissal column visualized with 2-deoxyglucose autoradiography are described. Cortical plasticity was evoked by vibrissal receptor lesions, deprivation or repetitive stimulation in neonatal and adult rats. The possible processes participating in changing the appearance of the cortical column are discussed. The role of reshaping of intracortical connections within the barrel field is suggested as an important mechanism of plasticity of the vibrissal cortical columns.
触须桶状区的解剖结构、细胞构筑和单位反应使其成为研究外周感受器操作的中枢效应的良好对象。本文综述了桶状系统的特性以及桶状皮层柱状功能的证据。描述了用2-脱氧葡萄糖放射自显影观察到的单个触须柱的可塑性变化。在新生和成年大鼠中，触须感受器损伤、剥夺或重复刺激可诱发皮质可塑性。讨论了可能参与改变皮质柱外观的过程。有人提出，桶状区内皮质内连接的重塑作用是触须皮质柱可塑性的重要机制。
