[Pilot] How Our Brains Predict and Shape Everyday Life
This is one of our early episodes. We shared a mic and the audio is a bit raw, so feel free to check out our latest episodes for a more polished experience.
Welcome to the first episode of Science Savvy with Carmen. In this episode, I explore how our brains work as prediction machines to help us make sense of the world around us. With my background in pharmacology and biomedical engineering, I break down the science behind how the brain constantly anticipates and adapts to everyday experiences.
This episode dives into how your brain predicts everything from the next note in a song to the social signals in a conversation. I unpack key theories in neuroscience and explain how the brain’s ability to make sense of uncertainty shapes your emotions, perceptions, and actions. If you’ve ever wondered how your brain seems to be one step ahead, this episode offers a practical and research-backed look at why prediction is at the core of everything we do.
Science Savvy is about understanding the hidden systems that guide your thoughts, your feelings, and your health. If you're curious about how your brain works and how that knowledge can empower your everyday life, you're in the right place.
