الوصف: The aim of this thesis is to analyse and describe the neurobiological basis of the systems derived from Reinforcement Sensitivity Theory (RST). To do so, we assessed the reactivity of these systems (the Behavioural Activation and Inhibition Systems and the Fight-Flight-Freeze System) by means of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ), as well as its brain correspondence through fMRI, both structurally and through resting state connectivity. Results confirm the frontostriatal and limbic involvement in approach (SR) and inhibition (SP) behaviours, respectively. We also observed differences linked to demographic (sex) and methodological (eyes open/closed at rest) aspects. In conclusion, results show stable brain patterns associated with the personality dimensions derived from RST. These data extend the knowledge about RST and its applicability in humans as a framework to study the predisposition toward different psychopathological disorders.
Description (Translated): El objetivo de esta tesis es analizar y describir las bases neurobiológicas de los sistemas derivados de la Teoría de la Sensibilidad al Refuerzo (TSR). Para ello, evaluamos la reactividad de estos sistemas (los Sistemas de Activación e Inhibición Conductual y el Sistema de Lucha-Huida-Congelamiento) mediante el cuestionario de Sensibilidad al Castigo y a la Recompensa (SCSR), así como su correspondencia cerebral a través de RMf tanto a nivel estructural como de conectividad en estado de reposo. Los resultados confirman la implicación frontoestriatal y límbica en conductas de aproximación (SR) e inhibición (SC), respectivamente. También observamos diferencias ligadas a aspectos demográficos (sexo) y metodológicos (ojos abiertos/cerrados en reposo). En conclusión, los resultados muestran rasgos cerebrales estables asociados a las dimensiones de personalidad derivadas de la TSR. Estos datos amplían el conocimiento y aplicabilidad de la TSR en humanos como marco para estudiar la predisposición a diferentes trastornos psicopatológicos.
