Philippa A. Johnson

I am a postdoctoral researcher in the CoCoSys Lab at Leiden University. My research explores the causes and consequences of changes in behavioural state. I use computational modelling of behavioural data from mice and humans to reveal some of the latent dynamics present during decision-making. I am currently investigating the role of pupil-linked arousal in causing transitions between being engaged and disengaged in a task.

I previously completed my PhD in the Timing Lab at the University of Melbourne, where I investigated how the visual system compensates for the time required for transmission and processing of information during motion perception. I showed that the early visual cortex compensates significantly for these neural delays by predictively encoding the position of moving objects, and that these predictive mechanisms affect perception of moving objects.
