    Nico Bunzeck
    UCL Institute of Cognitive Neuroscience, University College London, 17 Queen Square, London WC1N 3AR, UK
    Curr Biol 19:1294-300. 2009
    ..Thus, under the contextual influence of reward motivation, behaviorally relevant novelty signals emerge much faster than previously held possible in humans...
  2. pmc A common mechanism for adaptive scaling of reward and novelty
    Nico Bunzeck
    Institute of Cognitive Neuroscience, University College London, London WC1N 3AR, United Kingdom
    Hum Brain Mapp 31:1380-94. 2010
    ..These findings demonstrate a new mechanism for adjusting gain and sensitivity in declarative memory in accordance with contextual probabilities and expectancies of future events...
  3. pmc Anticipation of novelty recruits reward system and hippocampus while promoting recollection
    Bianca C Wittmann
    Wellcome Trust Centre for Neuroimaging, Institute of Neurology, University College London, 12 Queen Square, London, UK
    Neuroimage 38:194-202. 2007
    ..In more general terms, the data suggest that dopaminergic processing of novelty might be important in driving exploration of new environments...
  4. pmc Dopamine modulates episodic memory persistence in old age
    Rumana Chowdhury
    Institute of Cognitive Neuroscience, University College London, London, WC1N 3AR, United Kingdom
    J Neurosci 32:14193-204. 2012
    ..This lasting improvement even for weakly encoded events supports a role for dopamine in human episodic memory consolidation, albeit operating within a narrow dose range...

    Emrah Duzel
    Institute of Cognitive Neuroscience and Department of Psychology, University College London, 17 Queen Square, London WC1N 3AR, UK
    Neurosci Biobehav Rev 34:660-9. 2010
    ..We propose that maximizing the use of this mechanism by maintaining mobility and exploration of novel environments could be a potential mechanism to slow age-related decline of memory...

    Lluis Fuentemilla
    Institute of Cognitive Neuroscience, University College London, London, UK
    Curr Biol 20:606-12. 2010

    Institute of Cognitive Neuroscience, University College London, 17 Queen Square, London, WC13 NAR, UK
    Trends Neurosci 32:321-8. 2009
    ..We outline how systematic investigation of the functional parcellation of the SN/VTA in animals, new developments in fMRI analysis and combined PET-fMRI studies can narrow the gap between fMRI and dopaminergic neurotransmission...

    Marc Guitart-Masip
    Institute of Cognitive Neuroscience, University College London, London WC1N 3AR, United Kingdom
    J Neurosci 30:1721-6. 2010
