将大鼠的一对面部须毛粘合以便提供对须毛的同时刺激,4～8d后利用微电极在初级体感皮层测定各须毛的代表区,发现粘合须毛与正常对照大鼠须毛及自身的未粘合须毛相比,其皮层代表区有了显著的改变,主要是该对须毛代表区会聚面积的扩大。这一发现支持过去的假设;皮层代表区及感受野的形成是由输入的相对强度及输入的时间结构决定的。
A pair of facial hair of the rat was glued to provide simultaneous stimulation of the hairy hair. After 4 to 8 days, the representative regions of the hairy beard were measured in the primary somatosensory cortex by microelectrode. It was found that the adhesive whiskers and the normal control rat Hair and its own unbonded hair compared to its cortical representation of the area has been significantly changed, mainly on the representative area of beard hair converging area expanded. This finding supports the hypothesis of the past; the formation of cortical representation and receptive field is determined by the relative intensity of the input and the temporal structure of the input.
