The work that is sent to this journal must be original, not published or sent to be published elsewhere; and if it is accepted for publication, authors will agree to transfer copyright to International Journal of Psychological Research.
To give up copyright, the authors allow that, International Journal of Psychological Research, distribute the work more broadly, check for the reuse by others and take care of the necessary procedures for the registration and administration of copyright; at the same time, our editorial board represents the interests of the author and allows authors to re-use his work in various forms. In response to the above, authors transfer copyright to the journal, International Journal of Psychological Research. This transfer does not imply other rights which are not those of authorship (for example those that concern about patents). Likewise, preserves the authors rights to use the work integral or partially in lectures, books and courses, as well as make copies for educational purposes. Finally, the authors may use freely the tables and figures in its future work, wherever make explicit reference to the previous publication in International Journal of Psychological Research. The assignment of copyright includes both virtual rights and forms of the article to allow the editorial to disseminate the work in the manner which it deems appropriate.
The editorial board reserves the right of amendments deemed necessary in the application of the rules of publication.

Resumen
Un asunto importante en neurociencia social-cognitiva del desarrollo tiene relación con la naturaleza y la función de los enlaces neuronales entre la percepción de la acción y la producción de la misma en el desarrollo temprano del ser humano. Aquí documentamos un patrón somatotópico de la actividad de la EEG del Ritmo Mu sensorimotor en bebés de 14 meses de edad. La EEG fue registrada durante ensayos interactivos en los cuales los bebés activaron un objeto nuevo utilizando sus propias manos o pies (ensayos de "ejecución") y vieron a un experimentador usar sus manos o pies para lograr el mismo objetivo (ensayos de "observación"). En los electrodos centrales que cubren las áreas sensoriomotoras correspondientes a la mano (C3/C4), el poder del Ritmo Mu se redujo (indicando una mayor activación cortical) durante la ejecución por los bebés de actos de la mano en comparación con actos del pie. Para los electrodos centrales que cubren el área sensoriomotora correspondiente al pie (Cz), el poder Mu se redujo durante la ejecución de actos del pie versus actos de la mano. Sorprendetemente, patrones somatotópicos similares fueron encontrados tanto en la ejecución como en la observación de la acción. Tenemos la hipótesis de que estos patrones somatotópicos indican un mapeado intracorpóreo de las partes del cuerpo correspondientes entre uno mismo y los otros. Además, proponemos que la capacidad de los bebés para identificar equivalencias respecto a las partes del cuerpo entre ellos mismos y el otro es la base de la imitación infantil y es un bloque de construcción ontogenético para los sentimientos de intersubjetividad que experimentamos cuando nos comprometemos socialmente con otras personas.
