- Learning and generalization under ambiguity: an fMRI studyJ R Chumbley
The Wellcome Trust Centre for Neuroimaging, University College London, London, United Kingdom
PLoS Comput Biol 8:e1002346. 2012..These findings suggest candidate neuronal systems that may be involved in aberrations of generalization, such as over-confidence...
- A Metropolis-Hastings algorithm for dynamic causal modelsJustin R Chumbley
Wellcome Centre for Neuroimaging, Institute of Neurology, UCL, 12 Queen Square, London, WC1N 3BG, UK
Neuroimage 38:478-87. 2007..Reassuringly, we observe that the posterior is, for all practical purposes, insensitive of the choice of prior...
- Attractor models of working memory and their modulation by rewardJustin R Chumbley
Wellcome Trust Centre for Neuroimaging, Institute of Neurology, UCL, 12 Queen Square, London, WC1N 3BG, UK
Biol Cybern 98:11-8. 2008..We discuss the implications of these findings for theoretical formulations of basal and dopamine (DA)-modulated neural bump- attractor networks of working memory...
- False discovery rate revisited: FDR and topological inference using Gaussian random fieldsJustin R Chumbley
Wellcome Trust Centre for Neuroimaging, University College London, London, UK
Neuroimage 44:62-70. 2009..We describe the nature of the problem, illustrate it with some examples and suggest a simple solution based on controlling the false discovery rate of connected excursion sets within an SPM, characterised by their volume...
