Functional significance of the emotion-related late positive potential.
Stephen B. R. E. Brown,Henk van Steenbergen,Guido P. H. Band,Mischa de Rover,Sander Nieuwenhuis +4 more
TL;DR: Preliminary evidence that the LPP reflects a global inhibition of activity in visual cortex, resulting in the selective survival of activity associated with the processing of the emotional stimulus is provided.
Noradrenergic and Cholinergic Modulation of Belief Updating
Marieke Jepma,Marieke Jepma,Stephen B. R. E. Brown,Peter R. Murphy,Peter R. Murphy,Stephany C. Koelewijn,Boukje de Vries,Arn M. J. M. van den Maagdenberg,Sander Nieuwenhuis +8 more
TL;DR: A role for the noradrenergic and cholinergic systems in belief updating is suggested and the importance of studying interactions between different neuromodulatory systems is underlined.

Effects of arousal on cognitive control : Empirical tests of the conflict-modulated Hebbian-learning hypothesis
TL;DR: The goal of this research was to test a recent hypothesis about the mechanism underlying such associative-learning effects, the conflict-modulated Hebbian-learning hypothesis, which proposes that the effect of conflict on associative learning is mediated by phasic arousal responses.
The accessory stimulus effect is mediated by phasic arousal: A pupillometry study.
TL;DR: Results provide the first evidence that the AS effect is mediated by AS-evoked phasic arousal, and variation in reaction times on AS trials was selectively associated with pupil dilation during the early time window within which the AS had an effect.

Effects of clonidine and scopolamine on multiple target detection in rapid serial visual presentation.
Stephen B. R. E. Brown,Heleen A. Slagter,Martijn S. van Noorden,Erik J. Giltay,Nic J.A. van der Wee,Sander Nieuwenhuis +5 more
TL;DR: It is suggested that clonidine and scopolamine may impair temporal attention through a decrease in tonic alertness and that this decrease in alertness can be temporarily compensated by a phasic alerting response to a salient stimulus.
