By Thomas Pfeffer and Tobias Donner. The catecholaminergic neurotransmitters noradrenaline and dopamine are important regulators of brain state, and their function is impaired in several psychiatric disorders. An influential account posits that noradrenaline renders inference and decision-making more variable (exploratory)
New paper published in J Neuroscience: Multiple transient signals in human visual cortex associated with an elementary decision
By Thomas Meindertsma and Tobias Donner. Even the most elementary perceptual decisions result from complex cascades of neural computations in the brain. Such elementary decisions entail responding to simple patterns of light on the retina with arbitrarily mapped motor act. Previous research has shown
New paper published in eLife: Dynamic modulation of decision biases by brainstem arousal systems.
By Jan Willem de Gee and Tobias Donner. When asked to make repeated decisions we will often choose differently each time even when we are given the same information to inform our choice. A stock trader, for example, will typically be
New paper published in Nature Communications: Pupil dilation reflects decision uncertainty and alters choice patterns
By Anne Urai and Tobias Donner. The first paper of Anne’s PhD is now out! In this project, we investigated the relationship between pupil dilation, decision uncertainty and across-trial patterns of decisions. When making decisions about the world, each choice is
