Rapid skin indentations can produce strong tap-like sensations that contain little information about skin indentation depth. Although slower stimuli produce weaker sensations, subjects can more accurately identify how the position of the skin surface changes with respect to the deeper tissues. This dissociation between intensity and depth information suggests that intensity and depth are served by different neural circuits.
快速的皮肤压痕会产生强烈的类似轻敲的感觉，但这些感觉几乎不包含有关皮肤压痕深度的信息。虽然较慢的刺激产生的感觉较弱，但受试者能够更准确地识别皮肤表面相对于深层组织的位置是如何变化的。强度信息和深度信息之间的这种分离表明，强度和深度是由不同的神经回路负责的。
