Title: "Exploring and explaining biological motion processing with neural networks"


Seeing movement drives survival. It results from an uncertain interplay between evolution and experience, making it hard to isolate the drivers of computational architectures found in brains. In this presentation, I will show how artificial neural networks can be used to derive, and test, understanding of motion (mis)perception at the computational-, neural-, and perceptual-levels. I will demonstrate how diverse motion characteristics are largely explained by the statistical structure of natural images, rather than motion per se. Further, I will describe how causal inference can be solved using the activity of multisensory neurons to produce separate estimates of self- and object-motion while navigating through the environment. More broadly, I will demonstrate the conceptual value of marrying artificial systems with biological characterisation, moving beyond ‘black box’ reproduction of an architecture to advance understanding of complex systems like the brain.



About Neuroscience Seminars

Neuroscience seminars at the QBI play a major role in the advancement of neuroscience in the Asia-Pacific region. The primary goal of these seminars is to promote excellence in neuroscience through the exchange of ideas, establishing new collaborations and augmenting partnerships already in place.

Seminars in the QBI Auditorium are held on Wednesdays at 12-1pm, which are sometimes simulcast on Zoom (with approval from the speaker). We also occassionally hold seminars from international speakers via Zoom. The days and times of these seminars will vary depending on the time zone of the speaker. Please see each seminar listed below for details.
