CONFLICTS OF INTEREST
All authors are required to declare any potential conflicts of interest, including any financial, personal or other relationship with any person or organisation that might have an influence, or that might be regarded as having an influence on the scientific articles submitted to Rev Mex Neuroci. In the event there are no conflicts of interest, this fact should be expressed explicitly. The legend entitled "DECLARATION OF CONFLICTS OF INTEREST" should be part of the structure of the article and be placed after the conclusion and before the DECLARATION OF CONFLICTS OF INTEREST.
SOURCE OF FINANCING
Authors are urged to declare the source of economic financing for the execution of the research and/or the preparation of the manuscript, and to provide a brief description of the role of the financer, where applicable, in the design of the study, the collection of data, the analysis and interpretation of the information, the writing of the article and the decision to submit it to Rev Mex Neuroci. The declaration entitled "SOURCE OF FINANCING" should be part of the framework of the article and be placed after the DECLARATION OF CONFLICTS OF INTEREST and before the list of bibliographical references, in the writing of the article or the decision to submit it to Rev Mex Neuroci.
PREPARATION AND FORMATTING OF ARTICLES
We recommend consulting a recent Rev Mex Neurociencia article as means of complying with its style. Documents should feature numbered pages with double-spaced Arial, Times or Gill Sans font 11 or 12. The right margin of the document should NOT be justified for the purposes of editing. Use Microsoft Word 2.0 or later versions.
Only articles written in English (both the American and British variants) will be accepted. Rev Mex Neurociencia has no professional language editing services, reason for which the authors are entirely responsible for the accuracy and suitability of the written content.
With the exception of units of measurement, the exaggerated use of abbreviations should always be avoided. The meaning of an abbreviation should be explained the first time it appears. Original articles This is a paper on research testing a scientific hypothesis, with no more than 5,500 words (including the cover letter, the page providing information on the authors, the title page, summary, abstract, main text, list of references, tables and figure legends), with no more than six tables or figures (any combination is allowed) and no more than 40 references in the bibliographical list. The electronic article file should include the numbering of the pages and should comprise, in strict order, the following parts, separately:
Abstract: This page is dedicated to the abstract in English. This section of the article should be structured and comprise, in no more than 250 words, the following sub-sections: Objective, Methods, Results, Conclusions. A list of 3 to 5 keywords in English is required for indexing purposes.
Introduction: This page should include just one to three paragraphs (no more than 300 words in total) with a brief introduction focused on the essence and motivation of the study. Ideally, it should be based on the justification, importance, hypothesis and objective of the same. A clear justification on the approach to the issue in question should be provided if the article is a review. Literature citations begin here and should be registered in superscript Arabic numerals (for example: ...are poorly reported in numbers.21) after the punctuation mark, in the order in which the references are cited in the text (order of appearance).
Methods: This section should include a sentence specifying the type of study, the approval of the Ethics Committee and the requirement of Informed Consent (where applicable). The subject population (human or non-human), the study period, outcomes measured (dependent variables), operational definitions, the organization of the study (or experimental strategy), measurement of the variables and the collection of data all need to be clearly defined. After having provided this information, the last paragraph should deal with the statistical analysis, clearly specifying the methods of basic data description, analysis of association or inference, and the level of significance (in Rev Mex Neuroci). The level of significance should always be expressed with a non-cursive lowercase "p", always considering p< 0.05) as significant and the statistical package used (where applicable). Exact methods should be used in the analysis of categorical variables. Results should be presented as accurately as scientific values require (for example, measurements of association such as odds ratios should normally be reported to two decimal places). Except when the design of the article specifically requires, such as in non-inferiority studies, all the "p" values to be two-tailed. In general, "p" values of greater than 0.01 should be reported to two decimal places, "p" values of between 0.01 and 0.001 to three decimal places, and "p" values of less than 0.001 as "p < 0.001". The Methods section may include references to previous studies.
Results: This section should start with a description of the general characteristics of the study population. A description of both general and particular results. This section allows for the use of Charts (single-column tabulations, or in other words, listings), Tables (tabulations with more than one column and more than one row) and Figures (both single and compound illustrations, graphs and photographs). Use words first of all, use Tables if it is not possible with text only, and use Figures if this is not possible. Do NOT repeat the information contained in Tables or Figures in the text, just interpret it. If a Table or Figure is required, the text should only address the findings included in the Table or Figure superficially, do NOT repeat the same information. Do NOT refer to previous studies in this section.
Discussion: This section should first contain an interpretation of the results summarising the main findings of the scientific report, and a comparison with similar previous studies afterwards. Do not repeat numbers, percentages or raw data reported in the Results section. Discuss the results and explain to the scientific community why they are valuable and relevant for clinical practice. Provide a clear description of the limitations of the study, how the study could be improved in the future and what the future perspectives and courses of action are. This section should include references to preceding literature.

Citations and references: Insert the citations in relation to previous studies or conceptual references in superscript Arabic numerals, in order of appearance. Do NOT make citations in parentheses or brackets. A list of all the references used in order of appearance and in strict Rev Mex Neuroci style should be provided after the Conclusions section. The accuracy of the references is the responsibility of the authors. Do not place the list of references in alphabetical order. References cited in a Tables or Figures should appear in numerical order in accordance with the first reference made to the Table or Figure in the text. For example, if the last reference cited before the Table or Figure in question is reference 14, and the Table or Figure contains five references that have not yet been mentioned in the text, then the references contained in the Text or Figure should be numbered from 15 to 19; and consequently, the following unmentioned reference on returning to the text should be 20. If the references include more than six authors, the first six should be listed in MedLine style (for example: Ramírez-Castro CS) followed by "et al." The style of the references should be as follows:
Tables: Tables should appear in the article file after the list of references, starting with the title. Number the Tables with Arabic numerals in the order in which they are cited in the text. Use titles that provide a concise description of the content of the Table, thereby enabling the reader to understand the Table without having read the text. Tables may contain abbreviations but should feature a footnote with the meaning of the abbreviations. Provide the measurement units for all numerical data in the columns and rows of the Table. Place measurement units at the top of the column or at the far right of a row when the same measurement unit applies to all the data in this column or row. When preparing Tables with a grid, use a single grid for each Table, and not a separate grid for each column or row.
Figure legends: A legend should be placed above each figure and NEVER be part of the same.
Figures: High-resolution figures (at least 300 dpi/ppp) should be included on separate pages at the end of the text file, and NEVER between the Methods, Results or Discussion paragraphs. Do not include figure legends as part of the image itself. A brief title should identify each figure (for example, "Figure 1" or "Figure 2", etc.).
This is a paper on the narrative review of a neuroscience topic, with no more than 7,000 words (including the cover letter, the page providing information on the authors, the title page, summary, abstract, main text, list of references, tables and figure legends), with no more than seven tables or figures (any combination is allowed) and no more than 50 references in the bibliographic list. This specific type of article should comprise the following parts:
Abstract: This page is dedicated to the abstract. This section for this specific type of article should be non-structured (not composed of sub-sections), and should include, in no more than 200 words, a definition of the subject-matter in question, the importance of the same, the topics or sections to be addressed and a brief conclusion on the relevance of the Review. A list of 3 to 5 keywords is required for indexing purposes.
Introduction: This section should provide a clear justification for the presentation of the topic. The citations begin here, in accordance with the aforementioned guidelines.
Development: This section does not necessarily bear the title "Development". Instead, we recommend freestyle titles and subtitles, as required.
Conclusion: This section should specify the relevance of the topic in question and the future guidelines in fewer than 100 words.
