In order to navigate the world in an efficient manner, the brain seamlessly integrates signals received across multiple sensory modalities (Butler et al., 2010, 2011, 2015). A number of mathematical models have been used to investigate unisensory decision and reaction tasks, but to date very few have been extended to include multisensory processing. We will present an extension of the Wong and Wang (2006) model, a system of non-linear differential equations, that simulates the neuronal and behavioural processes in a visual-vestibular heading speeded reaction time task. To replicate similar fin
