Publisher Correction: Perception thresholds and qualitative perceptions for electrocutaneous stimulation

Correction to: Scientific Reports 10.1038/s41598-022-10708-9, published online 05 May 2022

The original PDF version of this Article contained errors in the Results section under the subheading ‘Pulse width’, where the confidence intervals of the median relative perception thresholds $A_{\text{p}}$ are illegible. These now read:

$A_{\text{p},20\mathrm{\mu }\text{s}}>A_{\text{p},50\mathrm{\mu }\text{s}}>A_{\text{p},100\mathrm{\mu }\text{s}}>A_{\text{p},150\mathrm{\mu }\text{s}}>A_{\text{p},200\mathrm{\mu }\text{s}}>A_{\text{p},250\mathrm{\mu }\text{s}}>A_{\text{p},500\mathrm{\mu }\text{s}}>A_{\text{p},1000\mathrm{\mu }\text{s}}>A_{\text{p},2000\mathrm{\mu }\text{s}}$.

The confidence intervals of the median relative attention thresholds $A_{\text{a}}$ show:

$A_{\text{a},20\mathrm{\mu }\text{s}}>A_{\text{a},50\mathrm{\mu }\text{s}}>A_{\text{a},100\mathrm{\mu }\text{s}}>A_{\text{a},150\mathrm{\mu }\text{s}}>A_{\text{a},200\mathrm{\mu }\text{s}}=A_{\text{a},250\mathrm{\mu }\text{s}}>A_{\text{a},500\mathrm{\mu }\text{s}}>A_{\text{a},1000\mathrm{\mu }\text{s}}>A_{\text{a},2000\mathrm{\mu }\text{s}}$.

The confidence intervals of the median relative intolerance thresholds $A_{\text{i}}$ show:

$A_{\text{i},20\mathrm{\mu }\text{s}}>A_{\text{i},50\mathrm{\mu }\text{s}}>A_{\text{i},100\mathrm{\mu }\text{s}}>A_{\text{i},150\mathrm{\mu }\text{s}}=A_{\text{i},200\mathrm{\mu }\text{s}}=A_{\text{i},250\mathrm{\mu }\text{s}}>A_{\text{i},500\mathrm{\mu }\text{s}}>A_{\text{i},1000\mathrm{\mu }\text{s}}=A_{\text{i},2000\mathrm{\mu }\text{s}}$.

Table 2 shows the results of linear regression $y={\beta }_0+{\beta }_1·x$ with the auxiliary variable for the pulse width $x=1/t_{\text{p}}$.
