• Methods and Results: 2200 words; inclusion of n (exact number of cases per group), F, t, df, and p values is mandatory, as well as number of replications (minimum of 2 attempts) of each independent experiment (if necessary add this information to the figure legend), randomization and exclusion criteria. Inclusion of species and strain, age, weight, sex, as well as ethics committee approval (when applicable) is also mandatory.
• Discussion: 400 words.

Upon acceptance, the authors will be instructed to format the manuscript according to the journal’s template.

Figures and tables: limited to 3 (half-page each), must be inserted at the end of the same file, above the respective legend. Illustrations should be accessible to color-blind readers; thus green and red combination should be avoided (we suggest magenta and green instead). We recommend that authors proof the images in “color blind mode” by changing the coloring of the image to simulate common forms of color blindness. In ImageJ software, that can be done in: Image > Color > Dichromacy, or Image > Color > Simulate Color Blindness. In Adobe Photoshop CC 2019, go to View > Proof Setup > Color Blindness. Redundant coding, such as different symbols or textures in addition to the color code, is also appreciated.

Citations: must be numbered as they appear, and references follow the Vancouver style (output styles for Zotero and Endnote).

Data availability: all data/code used in the manuscript must be available in open repositories (we suggest Zenodo or FigShare) and in open format (TSV, CSV, JASP, R or python, for example) from the initial submission under CC-BY 4.0 license.

Conflict of Interest: state all relevant conflict of interests from any of the authors in the manuscript. Inform the names of outlisted referees in the 'Comments for the Editor' box.

Keywords: add the keywords in the submission system and press 'Enter' to register them.

Pre-registration of attempts and reporting guidelines: we are committed to good practices in the scientific publication, therefore we recommend the pre-registration of attempts in OSF or any other platform. For reporting experiments using animals, we also suggest to authors to follow the ARRIVE guidelines, please find the PDF form here.

Peer review: articles and reviews will be submitted to single-blind peer review by default. However, if the authors request double-blind peer review, please remove or redact the names and affiliations in the submission file, and avoid explicit mentions of previously published material in the main text.

Plagiarism: accepted articles can be checked for plagiarism using Urkund.
