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.

Resumen
En la Anorexia Nervosa se observa un fenómeno que es la supresión del apetito. Poco se conoce sobre los factores biológicos y psicológicos (top-down) que mantienen este estado patológico. De cualquier modo la Anorexia Nervosa es un modelo biológico, psicológico y social de donde la principal característica conductual es la inhibición de la conducta alimentaria. Objetivo: Explorar las áreas cerebrales asociadas a la apetencia de los alimentos mediante la Resonancia Magnética Funcional en mujeres con Anorexia Nervosa. Métodos: Los sujetos fueron cinco mujeres con Anorexia Nervosa Restrictiva y cinco mujeres controles de similar edad y de bajo peso. Los sujetos fueron introducidos al resonador magnético mientras observan imágenes evocadoras de apetencia, en estado de ayuno y bajo la instrucción de imaginar que estaban comiendo lo que se les presentaba. Resultados: Al comparar las diferencias en las áreas de activación entre los sujetos cuatro regiones difirieron significativamente el cingulo anterior, la región frontal medial izquierda y derecha e izquierda del mesencéfalo Conclusiones: Las pacientes con anorexia nervosa presentaron áreas de actividad cerebral diferentes que los controles durante la exposición visual de comida en estado de hambre y con la evocación de pensamientos con el comer; estas regiones pudiesen estar implicadas con el reforzamiento y el auto-control.
