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
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
Linking pupil dilation to neural activity in the locus coeruleus
By Anne Urai and Thomas Meindertsma. Last week, we read the latest paper from Josh Gold’s lab: Joshi et al. Relationships between Pupil Diameter and Neuronal Activity in the Locus Coeruleus, Colliculi, and Cingulate Cortex. Neuron (2016). The pupil dilates
