Resumen

La reciente utilización de técnicas de resonancia magnética ha proporcionado una información muy interesante acerca de los cambios que tienen lugar en el cerebro durante los años de la adolescencia. Estos cambios afectan fundamental a la corteza prefrontal, estructura fundamental en muchos procesos cognitivos y que experimenta un importante desarrollo a partir de la pubertad que no culmina hasta los primeros años de la adultez temprana. Otros cambios afectan al circuito mesolímbico, relacionado con la motivación y la búsqueda de recompensas, que va a verse influido por las alteraciones hormonales
asociadas a la pubertad. Como consecuencia de esas modificaciones, durante los primeros años de la adolescencia se produce un cierto desequilibrio entre ambos circuitos cerebrales, el cognitivo y el motivacional, que puede generar cierta vulnerabilidad y justificar el aumento de la impulsividad y las conductas de asunción de riesgos durante la adolescencia. Estos hallazgos y sus implicaciones prácticas para la educación y la política social son presentados y discutidos en este artículo.
