Costumero, Víctor; Barrós-Loscertales, Alfonso; Bustamante, Juan Carlos; Fuentes-Claramonte, Paola; Rosell Negre, Patricia; Ventura Campos, Mercedes; Avila, Cesar Springer (2014-04)Existing evidence suggests that the presence of reward cues modifies the activity in attentional networks, however, the nature of these influences remains poorly understood. Here, we performed independent component analysis ... -

Costumero, Víctor; Rosell Negre, Patricia; Bustamante, Juan Carlos; Fuentes-Claramonte, Paola; Adrián-Ventura, Jesús; Palomar-García, María-Ángeles; Miró-Padilla, Anna; Llopis, Juan José; Sepulcre, Jorge; Barrós-Loscertales, Alfonso Wiley (2021-11)Previous investigations have used global graph theory measures in order to disentangle the complexity of the neural reorganizations occurring in cocaine use disorder (CUD). However, how these global topological alterations ... -
Individual differences in the behavioral inhibition system are associated with orbitofrontal cortex and precuneus gray matter volume
Bustamante, Juan Carlos; Costumero, Víctor; Fuentes-Claramonte, Paola; Avila, Cesar; Barrós-Loscertales, Alfonso; Rosell Negre, Patricia Springer-Verlag (2012-09)The Behavioral Inhibition System (BIS) is described in Gray’s Reinforcement Sensitivity Theory as a hypothetical construct that mediates anxiety in animals and humans. The neuroanatomical correlates of this system are not ... -
