Abstract
El Trastorno Límite de la Personalidad es un trastorno grave que genera en aquellos que lo padecen un intenso sufrimiento emocional y disfunciones severas del comportamiento. Una de las principales características de los pacientes con TLP es la existencia de una marcada inestabilidad afectiva, caracterizada por la tendencia a estados emocionales negativos tales como la ira, la ansiedad y la disforia (Lieb et al., 2004). Otros síntomas nucleares de este trastorno son los comportamientos impulsivos, las autolesiones, el abuso de sustancias y la promiscuidad sexual especialmente en el contexto de estados emocionales negativos, síntomas que también estarían vinculados a la existencia de una disregulación emocional de base (Clarkin et al., 2005). Los mecanismos neurales subyacentes a esta disregulación emocional, característica de los pacientes con TLP pueden ser estudiados utilizando diferentes tipos de técnicas funcionales, tanto a través de pruebas de neuroimagen como mediante abordajes electrofisiológicos. Los modelos dimensionales de la emoción conciben la estructura de las emociones a partir de dos dimensiones estratégicas principales, la valencia afectiva y el arousal (Lang, 1994; Bradley, et al., 2001). La valencia o polaridad emocional, es el grado de placer o desagrado, con un rango que va desde la atracción y el placer hasta la aversión y el displacer. El arousal o intensidad emocional es el grado de activación cuyo rango va desde la excitación a la calma. La dimensión valencia emocional se ha asociado con la activación de los sistemas motivacionales apetitivo o de defensa, mientras que la dimensión arousal ha sido considerada como el grado de activación de cada sistema motivacional primario o de ambos (Lang, 1995; Cacioppo y Berntson, 1994)...
Borderline personality disorder (BPD) is a severe condition causing intense emotional suffering and behavioral dysfunction. A major feature of BPD is affective instability which is characterized by a propensity toward intense negative emotional states like anger, anxiety and dysphoria (Lieb et al., 2004). Other core symptoms of borderline personality disorder are impulsive behaviors, self-mutilation, substance abuse and sexual promiscuity particularly in the setting of negative affective states (Clarkin et al., 2005). The neural mechanisms underlyng the characteristic emotional dysregulation of these patients can be nvestigated using differente types of functional techniques, including neuroimaging and electrophysiological approaches. Dimensional emotion theories consider arousal and valence as the primary components of emotions in human beings (Lang et al., 1994; Bradley et al., 2001). Valence (polarity) is the extent of pleasure or unpleasantness, and has been associated with the activation of the appetitive or defensive motivational system, respectively. Arousal (intensity) has been considered as the extent of activation of these two motivational systems (Lang, 1995; Cacioppo y Berntson, 1994).These dimensions are correlated. More negative and more pleasant stimuli are experienced as more arousing (Lang et al., 1995; Heller et al., 1997) The right temporoparietal cortex (TPC) is involved in modulating emotional arousal while the frontal lobes are the substrate of the valence dimension of emotion...
