In this episode, I explore the history, science, and clinical promise of psychedelics. This was actually my Master's Thesis topic so very fun episode for me! We cover everything from how the psychedelics actually work, by acting brain (serotonin) receptors to increase neuroplasticity (make your brain more malleable), disrupt rigid brain patterns, and increase brain "entropy"... and, more importantly, why those effects may help us treat conditions such as PTSD and treatment‑resistant depression. The episode also discusses the current clinical evidence (including a critical appraisal of its robustness), logisitcal and ethical challenges, and the importance of use within therapeutic / research settings only.

In this episode we talk about "having great genes", but also weird ones, ancient viral ones, and even one named after Sonic Hedgehog (look it up!). W dive into how your DNA is more like a script with a dimmer switch than a fixed destiny. From epigenetics and retroviruses to schizophrenia research, stem cells, and the pitfalls of 23andMe, we explore the science written into your genome. Thank you to Aitana Padilla for coming on the show. Aitana is a neuroscientist in training with a deep focus on the genetics of mental health. She currently investigates how human endogenous retroviruses (remnants of ancient viral infections embedded in our DNA) may influence schizophrenia!   Further reading and references: Human Endogenous Retroviruses as Pathogenic Factors in Schizophrenia: Slokar G, Hasler G.

Welcome to the Consciousness episode, part of Science Savvy with Carmen. In this episode, I explore what it really means to be conscious and how self-awareness shapes who we are. With my background in pharmacology and biomedical engineering, I break down the science behind consciousness and unpack how it shows up in your daily life. This episode covers everything from classic philosophical ideas like Descartes’ “I think, therefore I am” to modern neuroscience frameworks such as Crick’s Astonishing Hypothesis and Tononi’s information integration theory. We explore how brain chemistry, genetics, and personal experience come together to influence identity, self-esteem, and the feeling of being a self at all. Whether you’re curious about how the brain creates your sense of self or interested in the science behind awareness and emotion, this episode offers clear and engaging insights grounded in real research. Science Savvy helps you understand the systems shaping your thoughts, health, and behavior. If you're ready to explore your body and brain with a little more clarity, you're in the right place.
