原始语种摘要: Publisher Summary(#br)The majority of studies demonstrating a functional plasticity in the adult brain have been of the somatosensory system. This chapter focuses on short-term plasticity in adult somatosensory cortex. Studies showing short-term plasticity support the general concept that plasticity may result from the unmasking of normally unexpressed inputs to a cortical locus. Despite the clear demonstration of such unmasking, an explanation for the way this occurs is not immediately apparent. The basis of the problem is that a peripheral denervation of a small body part leads to expansion of the receptive field of some cortical neurons onto adjacent body areas but does not directly affect the input from these areas. The areas around a normal receptive field can contribute inhibitory...
