Neural correlates of attention and arousal: insights from electrophysiology, functional neuroimaging and psychopharmacologyJ T Coull
Wellcome Department of Cognitive Neurology, Institute of Neurology and University College London, UK
Prog Neurobiol 55:343-61. 1998..g. attentional orienting), the dopaminergic system is associated with more 'executive' aspects of attention such as attentional set-shifting or working memory...
Differential activation of right superior parietal cortex and intraparietal sulcus by spatial and nonspatial attentionJ T Coull
Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London, WC1N 3BG, United Kingdom
Neuroimage 8:176-87. 1998..Finally, PPC activations in spatial WM tasks are likely to be due to a combination of spatial perception, attention, and WM, rather than to any of these individually...
Monitoring for target objects: activation of right frontal and parietal cortices with increasing time on taskJ T Coull
Wellcome Dept of Cognitive Neurology, London, UK
Neuropsychologia 36:1325-34. 1998....
Noradrenergically mediated plasticity in a human attentional neuronal networkJ T Coull
Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London, WC1N 3BG, United Kingdom
Neuroimage 10:705-15. 1999..More generally, the results illustrate the dynamic plasticity of cognitive brain systems following neurochemical challenge...
Orienting attention in time: behavioural and neuroanatomical distinction between exogenous and endogenous shiftsJ T Coull
Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London, UK
Neuropsychologia 38:808-19. 2000..These findings suggest that distinct brain areas are involved in redirecting attention based upon sensory events (bottom-up, exogenous shifts) and based upon cognitive expectations (top-down, endogenous shifts)...
The noradrenergic alpha2 agonist clonidine modulates behavioural and neuroanatomical correlates of human attentional orienting and alertingJ T Coull
Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London WC1N 3BG, UK
Cereb Cortex 11:73-84. 2001..Furthermore, we have demonstrated lateralized neuroanatomical substrates for the noradrenergic modulation of human attentional orienting in the spatial and temporal domains...
The predictive value of changes in effective connectivity for human learningC Buchel
The Wellcome Department of Cognitive Neurology, Institute of Neurology, 12 Queen Square, London WC1N 3BG, UK
Science 283:1538-41. 1999..The time course of these plastic changes was highly correlated with individual learning performance, suggesting that interactions between brain areas underlie associative learning...
Dissociating neuromodulatory effects of diazepam on episodic memory encoding and executive functionJ T Coull
Wellcome Department of Cognitive Neurology, Institute of Neurology, London, UK
Psychopharmacology (Berl) 145:213-22. 1999..Deficits in tests of executive function are also reported. In this study, we ask whether the latter effects are secondary to mnemonic impairment, or reflect specific and distinct effects of benzodiazepines on executive function...
