Which afferents contribute to the perceived intensity of a stimulus?
According to hypothesis 3, only afferents whose RFs are located under or near the contact area (i.e., the area over which the effective amplitude is the actual amplitude of the stimulus) (Fig. 10) contribute to the perceived intensity of the stimulus. In the present experiment, the contactor and surrounding area spanned ∼7 mm 2.

How do neural excitability and sensory input determine intensity perception?
Neural excitability and sensory input determine intensity perception with opposing directions in initial cortical responses eLife 10 :e67838. Perception of sensory information is determined by stimulus features (e.g., intensity) and instantaneous neural states (e.g., excitability).

What is the entropy of a stimulus?
The entropy of the stimulus H (S) represents the maximum information that could be encoded, from which the stimulus equivocation H (S | R) is lost. Therefore the information about the stimulus preserved in the neural response (termed 'mutual information') is I (R, S) = H (S) – H (S | R).

Are Submodalities integrated to form a coherent percept of stimulus intensity?
Nevertheless, a major conclusion of this study is that signals from three submodalities, which convey information about different aspects of the stimulus (i.e., form, motion and vibration), are integrated to form a coherent percept of stimulus intensity.

Does stimulation of the sense organs produce a concentration–dose effect?
The stimulation of sense organs involves rate-related phenomena, resulting in a concentration-dose effect situation similar to that described for the uptake of carbon monoxide and formation of carboxyhaemoglobin.
