Dr. Sanjay Gupta travels to Cuba to investigate one of the most complex and controversial brain mysteries in recent years known as "Havana Syndrome." First reported by two dozen U.S. officials in Havana, Cuba starting in 2016, these unexplained health incidents have since multiplied to include hundreds of reports of concussion-like injuries around the globe. Despite various government investigations, American officials have yet to make clear what is behind these injuries and whether a directed energy weapon may be to blame. Dr. Gupta sets out to explain the truth behind "Havana Syndrome," the extent of its impact on the brain, and the potential continuing threat facing government officials at home and abroad.

When psychedelics were first studied more than 50 years ago, researchers noticed that they were useful in helping people explore a greater sense of self. Now, after a half-century hiatus, scientists are studying psychedelics like MDMA, psilocybin, and ketamine as treatment for depression, PTSD, anxiety, and other mental health conditions. So, what promise do they hold as therapeutics? Albert Garcia-Romeu, a researcher at John’s Hopkins University, joins Dr. Sanjay Gupta to talk about how psychedelics can alleviate mental suffering and what the path forward might look like.

For the past couple of months, we’ve explored the senses and how each one affects our health and well-being. In our last episode of this season, we examine a trait known as synesthesia – in which the senses intertwine, like seeing colors when you hear music or tasting flavor when you feel texture. Neurologist and author, Dr. Richard Cytowic, joins Dr. Sanjay Gupta to explain what happens in the brain when the senses blend. We’ll also hear from musical artist, Christen Lien, about what it’s like to live and perform with synesthesia. To learn more about how CNN protects listener privacy, visit cnn.com/privacy

Close your eyes and just listen. Even if you aren’t actively thinking about the noises happening around you, your brain is constantly processing sound. That’s because, unlike your eyes, your ears never close. In fact, Northwestern neurobiology professor Nina Kraus, says listening is one of the hardest tasks we ask our brains to do. On today’s episode, Kraus explains how the sounds we’re surrounded by everyday – like a noisy leaf blower or the soothing sound of music – really matter and can impact our physical and mental health. Plus, she shares tips for building a healthy “sonic world.” To learn more about how CNN protects listener privacy, visit cnn.com/privacy
