  • A Brain Model of Disturbed Self-Appraisal in Depression
    Davey, Christopher G.; Breakspear, Michael; Pujol, Jesús; Harrison, Ben J. (American Psychiatric Association, 2017)
    OBJECTIVE: A disturbed sense of self is a core feature of depression. The medial prefrontal cortex, which has a central role in self-appraisal processes, is often implicated in the illness, although it remains unclear how ...
  • Abnormal Social Reward Responses in Anorexia Nervosa: An fMRI Study.
    Via, Esther; Soriano Mas, Carles; Sánchez, Isabel; Forcano, Laura; Harrison, Ben J.; Davey, Christopher G.; Pujol, Jesús; Martínez Zalacaín, Ignacio; Menchón, José M.; Fernández Aranda, Fernando; Cardoner, Narcís (Public Library of Science, 2015)
    Patients with anorexia nervosa (AN) display impaired social interactions, implicated in the development and prognosis of the disorder. Importantly, social behavior is modulated by reward-based processes, and dysfunctional ...
  • Attenuated frontal and sensory inputs to the basal ganglia in cannabis users
    Blanco Hinojo, Laura, 1981-; Pujol, Jesús; Harrison, Ben J.; Macià, Dídac; Batalla, Albert; Nogué, Santiago; Torrens, Marta; Farré, Magí; Deus, Joan; Martín Santos, Rocío (Wiley, 2017)
    Heavy cannabis use is associated with reduced motivation. The basal ganglia, central in the motivation system, have the brain's highest cannabinoid receptor density. The frontal lobe is functionally coupled to the basal ...
  • Brain imaging of pain sensitization in patients with knee osteoarthritis
    Pujol Martí, Jesús, 1981-; Martínez-Vilavella, Gerard; Llorente-Onaindia, J.; Harrison, Ben J.; López-Solà, Marina; Blanco Hinojo, Laura, 1981-; Benito Ruiz, Pedro; Deus, Joan; Monfort Faure, Jorge (Elsevier, 2017)
    A relevant aspect in osteoarthritic pain is neural sensitization. This phenomenon involves augmented responsiveness to painful stimulation and may entail a clinically worse prognosis. We used functional magnetic resonance ...
  • Mapping the self in the brain's default mode network
    Davey, Christopher G.; Pujol, Jesús; Harrison, Ben J. (Elsevier, 2016)
    The brain's default mode network (DMN) has become closely associated with self-referential mental activity, particularly in the resting-state. While the DMN is important for such processes, it has functions other than ...
  • Neural signatures of human fear conditioning: an updated and extended meta-analysis of fMRI studies.
    Fullana Rivas, Miguel Ángel; Harrison, Ben J.; Soriano Mas, Carles; Vervliet, Bram; Cardoner, Narcís; Àvila-Parcet, A.; Radua, Joaquim (Nature Publishing Group, 2016)
    Classical Pavlovian fear conditioning remains the most widely employed experimental model of fear and anxiety, and continues to inform contemporary pathophysiological accounts of clinical anxiety disorders. Despite its ...
  • Neurodevelopmental correlates of the emerging adult self
    Davey, Christopher G.; Fornito, Alex; Pujol Nuez, Jesús; Breakspear, Michael; Schmaal, Lianne; Harrison, Ben J. (Elsevier, 2019)
    The self-concept - the set of beliefs that a person has about themselves - shows significant development from adolescence to early adulthood, in parallel with brain development over the same period. We sought to investigate ...
  • The contribution of brain imaging to the understanding of psychopathy
    Pujol Martí, Jesús, 1981-; Harrison, Ben J.; Contreras Rodríguez, Oren, 1985-; Cardoner, Narcís (Cambridge Medical Publications, 2019)
    Psychopathy is a personality type characterized by both callous emotional dysfunction and deviant behavior that affects society in the form of actions that harm others. Historically, researchers have been concerned with ...
