EmOntheBrain: How to Rewire Your Reality

Trevor and Eugene sit down with neuroscientist and content creator Emily McDonald (aka EmOnTheBrain) to explore how our brains shape the way we think, feel, and behave. From the real limits (and possibilities) of neuroplasticity to the surprisingly persistent pull of old habits, McDonald breaks down what’s actually happening inside our nervous systems. Along the way, the trio dive into Emily’s own neurological journey, how elite athletes train their brains for peak performance, and even the spiritual energy of Sedona — all in an effort to understand how we change, and why our brains don’t always make it easy.

In this episode of What Now? With Trevor Noah, featuring Trevor Noah and Eugene, EmOntheBrain: How to Rewire Your Reality explores neuroscience meets spirituality: habits, perception, and self-concept rewiring your life Emily McDonald explains habit formation as dopamine-driven learning that shifts from reward to cue-based craving, which is why triggers (ads, notifications, seeing food) can compel behavior even when you don’t consciously want it.
