Comparing motor activity with decision activity in the brain

In this Researcher Spotlight episode, Professor Redmond O'Connell describes using electroencephalography (EEG) to compare motor signals and decision signals in the brain.
In 2012, Redmond and his colleagues Simon Kelly and Paul Dockree published a paper describing their discovery of the centroparietal positivity (CPP), an event-related potential (ERP) relating to perceptual decision making. The CPP differed to known motor signals such as the lateralised readiness potential, for instance in its build-up rate.
Watch this short explainer from Redmond demonstrating how the two different categories of brain signals can be distinguished.

Research in the O'Connell lab focuses on the neural mechanisms underpinning high-level cognition. This work comprises both basic and translational research, employing pscyhophysics and computational modelling in combination with a range of psychophysiological techniques including EEG, fMRI, autonomic system measurement and transcranial stimulation. The teams' primary research interests include perceptual decision making, performance monitoring, and attention.
