Psychophysical studies in humans have demonstrated adaptation of the mechanoreceptive submodalities of flutter and vibration after prolonged presentation of a strong adapting, or conditioning, stimulus. In our studies we recorded from single neurons in cat primary somatosensory cortex, and followed a paradigm in which the response of a single unit was measured before and after the presentation of a strong conditioning stimulus. Our findings show no adaptive response in the 30 sec period immediately after cessation of the conditioning stimulus, and suggest that other parallel ascending pathways or somatosensory cortical areas other than SI account for these psychophysical observations.
人体的心理物理学研究表明,在长时间呈现强烈的适应性(或条件性)刺激后,颤振和振动的机械感受亚模态会出现适应性变化。在我们的研究中,我们记录了猫初级体感皮层单个神经元的活动,并遵循一种范式,即在呈现强烈的条件性刺激之前和之后测量单个神经元的反应。我们的研究结果表明,在条件性刺激停止后的30秒内没有适应性反应,并表明除了SI之外的其他平行上行通路或体感皮层区域可以解释这些心理物理学观察结果。
