Neuroaesthetics expert Dr. Oshin Vartanian explains how your brain responds to the spaces around you, why curves feel safe, why high ceilings free your thinking, and why so much of your reaction to a room is happening in the oldest, most primal parts of your brain.
This is Part 1 of a two-part series on neuroaesthetics. Here we cover the foundations - the primal brain, evolution, and the design features your brain reacts to before you're even aware of it. In Part 2, Dr. Vartanian goes deeper into the nervous system, creativity, emotional regulation, and therapeutic design.
In this episode we explore the neuroscience of the built environment with Dr. Oshin Vartanian. We get into how the brain computes beauty, why our preferences are rooted in survival, and what that means for designing homes that genuinely support how we think and feel.

In this episode:
- Why your preference for a beautiful space is driven by the brain's ancient reward circuitry.
- "Prospect and refuge": why we're drawn to spaces that let us see out while feeling protected.
- Why even newborns and great apes prefer curves, and why angles can read as threat.
- The study showing the same talk raises cortisol more in an enclosed room than an open one.
- How high ceilings invite mind-wandering and more abstract, creative thought.
- Why natural contrast and complexity register in your brain before you consciously notice.
- Why there's no universal "right" design, individual history always shapes the response.
Guest: Dr. Oshin Vartanian is a leading voice in neuroaesthetics, a Professor at the University of Toronto, and President of the International Association of Empirical Aesthetics (IAEA). His research uses brain imaging to study how design, curvature, ceiling height, openness, contrast, shapes human cognition, emotion, and wellbeing, bridging psychology, neuroscience, and architecture.
