Your eyes don't see the world; your brain constructs it. But how, and what does it miss along the way?

In this episode of Neuroscience and Beyond, we speak with Prof. Nicole Rust, Professor of Psychology at the University of Pennsylvania, whose research combines behavioral experiments, #neural recordings, and #computational models to understand how we see, remember, and experience the world. Recently, she decided to embark on a new journey and apply her expertise to study the neuroscience of mood.

We explore how the brain transforms raw light into meaningful #perception, from the #retina through a hierarchy of visual areas all the way to object recognition in the inferotemporal cortex. We discuss how #attention shapes what enters #memory, why humans can recognize thousands of images seen only once, and why mood remains one of the hardest problems in neuroscience.

The conversation also unpacks the central argument of her book, Elusive Cures: that treating conditions like depression will require abandoning the "broken domino" model of disease and embracing the brain as a complex dynamical system.

In this episode, you'll learn:

• How the #brain transforms light into perception
• Why attention acts as a filter and why we miss more than we think
• How the brain stores thousands of images with striking detail after just a single viewing
• Why we still cannot look at a brain and determine what mood is
• What hinders us from developing more treatments for brain disorders
• Why we should see the brain as a complex dynamical system
