\begin{abstract}
Hi Reddit! I'm David Moreau and I'm a cognitive neuroscientist in the
department of Psychology at the University of Auckland, New Zealand. My
research focuses on the dynamics and plasticity of cognitive function,
that is, how the brain changes and adapts to its environment. Before
moving to Auckland in 2014, I've worked at Princeton University, New
Jersey, where I developed, tested and validated the idea of combining
physical and cognitive demands to elicit improvements in brain function.
This type of intervention, blending brain training and physical
exercise, allows preserving the ecological components of naturalistic
activities, and has ramifications both for clinical (e.g. children with
neurodevelopmental disorders, adults with dementia and patients in
post-stroke recovery) and non-clinical populations. I'm here to answer
questions about a recent paper my group published in the journal eLife
(https://doi.org/10.7554/eLife.25062), where we showed that short,
intense bursts of exercise can induce meaningful improvements in brain
function, or queries related to anything in my area of expertise more
broadly. I'll start answering questions at 3pm EST. AMA!%
