by Zhu, M., and Gong, Q. (2023). Front. Neurosci. 17:1254423. doi: 10.3389/fnins.2023.1254423

In the original article, there are two references cited incorrectly.

One is in the section 2.5 EEG data collection and pre-processing:

“To minimize potential interference from alcohol, coffee, cola, and tea on EEG recordings (Barry et al., 2011; Foxe et al., 2012; Vanneste and De Ridder, 2012b).” It should be To minimize potential interference from alcohol, coffee, cola, and tea on EEG recordings (Barry et al., 2011; Foxe et al., 2012; Vanneste and De Ridder, 2012a).

The reference is:

Vanneste, S., and De Ridder, D. (2012a). The use of alcohol as a moderator for tinnitusrelated distress. Brain Topogr. 25, 97–105. doi: 10.1007/s10548-011-0191-0

The other is in the section 4.1 Whole-brain spectral analysis:

“qEEG (Van Der Loo et al., 2009; Vanneste and De Ridder, 2012a; Meyer et al., 2014) and MEG studies··” It should be qEEG (Van Der Loo et al., 2009; Vanneste and De Ridder, 2012b; Meyer et al., 2014) and MEG studies··

The reference is:

Vanneste, S., and De Ridder, D. (2012b). The auditory and non-auditory brain areas involved in tinnitus. An emergent property of multiple parallel overlapping subnetworks. Front. Syst. Neurosci. 6:31. doi: 10.3389/fnsys.2012.00031

In the published article, for the keeping consistency of the whole article, the font of some words should be consistent, either in orthography or italics. Specifically as follows:

(1) Page 05, Section 2.7 Microstate analysis

The original sentence:

$\begin{array}{l}GFP(t)=\sqrt{\frac{{\left[{\displaystyle {\sum }_i^N}(Vi(t)-Vmean(t))\right]}^2}{N}}\end{array}$

Where N represents the number of electrodes in the EEG data (i = 1: 60), V represents the electrical potential measured over the scalp. Vi(t) represents the instantaneous electrical potential at electrode i and time t, and Vmean(t) represents the average electrical potential at all electrodes at time t.

The corrected sentence appears below:

$\begin{array}{l}GFP(t)=\sqrt{\frac{{\left[{\displaystyle {\sum }_i^N}(Vi(t)-Vmean(t))\right]}^2}{N}}\end{array}$

Where N represents the number of electrodes in the EEG data (i = 1: 60), V represents the electrical potential measured over the scalp. Vi(t) represents the instantaneous electrical potential at electrode i and time t, and Vmean(t) represents the average electrical potential at all electrodes at time t.

(Authors considered that formula and text should keep consistency in font, it's either all in orthography or all in italics)
