Adaptive circuit dynamics across human cortex during evidence accumulation in changing environments
Murphy PR, Wilming N, Hernandez-Bocanegra DC, Prat-Ortega G, Donner TH (2021). Adaptive circuit dynamics across human cortex during evidence accumulation in changing environments. Nature Neuroscience. By Peter Murphy & Tobias Donner. The neurobiology of perceptual decision-making has witnessed an impressive
Brainstem Modulation of Large-Scale Intrinsic Cortical Activity Correlations.
van den Brink RL, Pfeffer T & Donner TH. 2019. Frontiers in Human Neuroscience. 13:340. doi: 10.3389/fnhum.2019.00340. Brain activity fluctuates continuously, even in the absence of changes in sensory input or motor output. These intrinsic activity fluctuations are correlated across brain regions and
Confidence predicts speed-accuracy tradeoff for subsequent choices
Desender K, Boldt A, Verguts T & Donner TH. (2019) Confidence Predicts Speed-accuracy Tradeoff for Subsequent Choices. eLife. 8: e43499. By Kobe Desender & Tobias Donner. Humans can provide precise judgments of the accuracy of their choices. When we feel confident in
Choice history biases subsequent evidence accumulation
Urai AE, de Gee JW, Tsetsos K, Donner TH. (2019) Choice history biases subsequent evidence accumulation. eLife, 8:e46331. By Anne Urai & Tobias H. Donner. To study the mechanisms of decision-making, researchers often treat individual decisions as isolated events. However,
New piece in Science Breaker
We just published a lay summary of the Current Biology 2018 Report by Talluri et al on confirmation bias in Science Breaker.
New paper out in Current Biology: Confirmation bias through selective overweighting of choice-consistent evidence
Confirmation bias through selective overweighting of choice-consistent evidence, Current Biology, 28, 1-8 (2018). By Bharath Chandra Talluri & Tobias Donner. Confirmation bias is the tendency to interpret new information such that it agrees with one’s pre-existing beliefs. This cognitive bias is
New paper out in Scientific Reports: Task-evoked pupil responses reflect internal belief states
Task-evoked pupil responses reflect internal belief states, Scientific Reports (2018) By Olympia Colizoli, Jan Willem de Gee, Anne E. Urai & Tobias Donner Pupil diameter is a reliable marker of central arousal states and neuromodulatory responses. The pupil dilates whenever
New paper out in J Neuroscience: Amplification and Suppression of Distinct Brain-wide Activity Patterns by Catecholamines
By Ruud van den Brink & Tobias Donner. A class of neurotransmitters known as catecholamines (norepinephrine and dopamine) play an important modulatory role in brain function. These catecholamines are synthesised by neurons clustered in small nuclei of the brainstem, which
New paper out in J Neuroscience: Surprise About Sensory Event Timing Drives Cortical Transients in the Beta Frequency Band
By Thomas Meindertsma & Tobias Donner. The brain continuously tracks the statistical structure of the environment to anticipate behaviorally relevant events. Deviations from such predictions cause surprise, a violation of the agent’s expectation about an event, which might be indicative
