Mainly the skin senses touch and warmth have been investigated. It is shown that the decision model describes the experimental data better than the threshold model. The experiments lead to the assumption that an internal noise exists, which is a neural activity being undistinguishable from the neural activity caused by small stimuli and which adds to the neural activity caused by the stimulus. The probability distribution of this internal noise can be considered to be gaussian. The relation between stimulus and neural activity is alinear for the touch sense. The question of whether noise of a multiplicative nature must be assumed is discussed.
主要对皮肤的触觉和温觉进行了研究。结果表明,决策模型比阈值模型能更好地描述实验数据。这些实验得出一个假设,即存在内部噪声,它是一种神经活动,与由小刺激引起的神经活动无法区分,并叠加到由刺激引起的神经活动上。这种内部噪声的概率分布可被认为是高斯分布。对于触觉而言,刺激与神经活动之间的关系是线性的。文中还讨论了是否必须假设存在乘法性质噪声的问题。
