Corrigendum: EEG-based spectral analysis showing brainwave changes related to modulating progressive fatigue during a prolonged intermittent motor task

In the published article, there was an error. Equation (2) is incorrect.

A correction has been made to Data Analysis, Statistical Framework, Paragraph Two. This sentence previously stated: Therefore, the ERSP analyses and the results reported here are based on the log-transformed ERSP in Equation (2) and its time-averaged quantity in Equation (3), both expressed in decibels (dBs):

$$\begin{array}{r}\text{ERSP}(f,t)=10{log}_{10}\left[\text{ERS}(f,t)-{\text{B}}_{\text{AVG}}(f)\right]\end{array}$$ (2)

$$\widetilde{\text{ERSP}}(f)=\frac{1}{r}{\displaystyle \sum _{\underset{\_}{t}\in R}\text{ERSP}(f,\underset{\_}{t})}$$ (3)

where

$$\begin{array}{r}{B}_{\text{AVG}}(f)=\frac{1}{pq}{\displaystyle \sum _{k=1}^p}{\displaystyle \sum _{\overline{t}\in Q}}{\left|S_k(f,\overline{t})\right|}^2\end{array}$$ (4)

and r denotes the cardinality of the set R of steady- or post-contraction time points.

The corrected sentence appears below: Therefore, the ERSP analyses and the results reported here are based on the log-transformed ERSP in Equation (2) and its time-averaged quantity in Equation (3), both expressed in decibels (dBs):

$$\begin{array}{r}\text{ERSP}(f,t)=10{log}_{10}\left[\text{ERS}(f,t)\oslash {\text{B}}_{\text{AVG}}(f)\right]\end{array}$$ (2)

$$\widetilde{\text{ERSP}}(f)\text{ }=\frac{1}{r}{\displaystyle \sum _{\underset{\_}{t}\in R}\text{ERSP}(f,\underset{\_}{t})}$$ (3)

where

$$\begin{array}{r}{B}_{\text{AVG}}(f)=\frac{1}{pq}{\displaystyle \sum _{k=1}^p}{\displaystyle \sum _{\overline{t}\in Q}}{\left|S_k(f,\overline{t})\right|}^2\end{array}$$ (4)

⊘ denotes Hadamard division, and r is the cardinality of the set R of steady- or post-contraction time points.
