Correction to: Scientific Reports https://doi.org/10.1038/s41598-021-94456-2, published online 03 August 2021


The original version of this Article contained errors.

The legends of Figure 1 and 2 were inadvertently switched.


The legend of Figure 1:


“Timeline of the experimental paradigm. Timeline of each assessment pre- and post-thermal stimuli with primary stimulus (at 25 °C) and secondary stimulus (at 5 °C). The cold test was induced by the immersion of the right hand in the water for 30 s or until feeling the first pain sensation with both stimuli and a break of 2 min between each trial.”


now reads:


“The fNIRS' optodes montage. Black dots represent detectors, and white dots represent sources. Left prefrontal cortex—channel 1–9 plus 11 and 12. Right prefrontal cortex—channel 12–20 plus Channel 9 and 10. Right motor cortex—channel 21–30. Left motor cortex—Chanel 31–40.”


The legend of Figure 2:


“The fNIRS' optodes montage. Black dots represent detectors, and white dots represent sources. Left prefrontal cortex—channel 1–9 plus 11 and 12. Right prefrontal cortex—channel 12–20 plus Channel 9 and 10. Right motor cortex—channel 21–30. Left motor cortex—Chanel 31–40.”


now reads:


“Timeline of the experimental paradigm. Timeline of each assessment pre- and post-thermal stimuli with primary stimulus (at 25 °C) and secondary stimulus (at 5 °C). The cold test was induced by the immersion of the right hand in the water for 30 s or until feeling the first pain sensation with both stimuli and a break of 2 min between each trial.”


The Acknowledgements section was omitted and now reads:


We thank the Fundo de Incentivo à Pesquisa e Eventos (FIPE) from the Postgraduate Research Group at the Hospital de Clínicas de Porto Alegre for all the financial support and consultancy services the institution provided since the beginning of the study.


Lastly, the Funding section was incomplete and now reads:


Research funding for Brazilian agencies: (i) Committee for the Development of Higher Education Personnel— CAPES (MZ, post-doctorate scholarship). (ii) National Council for Scientifc and Technological Development— CNPq (Grant Nos. 302688/2017-0 and 420826/2018-1 to W. C.).
