Matt dives deep into the science of memory with renowned neuroscientist Dr. Charan Ranganath, author of Why We Remember: Unlocking Memory's Power to Hold On to What Matters in today’s episode. Together, they explore the complex relationship between memory and the brain, touching on the roles of emotional significance, context, and even neuromodulators like dopamine in helping our brains decide which memories to retain and which to discard.

Dr. Ranganath shares his unique journey into memory research and insights from his pioneering work at the Dynamic Memory Lab at UC Davis, where his studies have reshaped our understanding of human memory. He also explains the diversity within memory types—such as episodic, semantic, and procedural memories—and why they’re all processed differently. Delving into extraordinary memory phenomena, he discusses hyperthymesia, false memories, and cases of severely deficient autobiographical memory, illustrating the varied ways people experience memory. This episode is a rich journey into the science and experience of memory, concluding with a refreshing reminder: sometimes, forgetting can be just as beneficial as remembering, offering us a balanced perspective on our memory's true role in daily life.

In Matt’s latest installment of his "Ask Me Anything" series, he once again joins forces with Dr. Eti Ben Simon to address a wide spectrum of listener questions. Beginning with a dive into the fascinating connections between sleep and medication effects, they unpack the ways various medications can impact sleep quality and patterns, from increasing alertness to potentially triggering vivid dreams or insomnia. Eti also brings a unique perspective on how different medications influence REM sleep and how timing your dosage may alleviate some side effects, highlighting the importance of discussing these nuances with a healthcare provider.

Listeners can look forward to intriguing discussions on sleep-related topics beyond just meds, as our hosts go on to explore questions about circadian rhythms, the impact of light exposure on melatonin and sleep health, and the potential benefits of sleeping naked for body temperature regulation and stress reduction. The episode also touches on the quirks of pet behavior in bed, why snoring happens, and the curious ways some animals experience sleep. Packed with science-backed insights, this AMA episode invites listeners to consider how everyday factors shape their sleep and overall well-being. And remember, if you have a sleep question, be sure to send it in to Matt or Eti as soon as possible!
