  • Liked old episodes better

    I preferred the earlier narrated format—it was concise and engaging. I’d love to hear more episodes in that style. The newer interview-style episodes feel longer and less interesting.

  • Podcast awesome… Eric Weinstein, unbearable

    I love this podcast and generally like the guest that Dr. Eagleman interviews. The conversations are informative and typically well balanced between more dense jargon and everyday language. However the February 2026 episode with Eric Weinstein was so hard to listen to because Weinstein seems so pretentious, condescending, and out of touch with what it means to be a “good person”. His perspective on Jim Watson suggests that he looks up to Watson even though Watson is a terrible human. Weinstein s... more

  • Painfully annoying bg music

    Just listened to the Sam Harris interview and found it almost impossible to listen to due to the horrendous music playing in the background. Why, oh why, would anyone feel the need to ruin a perfectly good podcast by playing bad music over the guest’s voice?

Talking Points

Recent interactions between the hosts and their guests.

Ep154 "Can a Depressed Brain Find Its Way Out?" with Jon Nelson
Q: What did you do after TMS, and how did you come to the decision to try deep brain stimulation (DBS)?
After failed medications and therapies, and a pivotal moment in which DBS was offered, he chose to undergo DBS at Mount Sinai under Dr. Helen Mayberg, which ultimately led to remission of suicidal thoughts and the brain disease.
Ep154 "Can a Depressed Brain Find Its Way Out?" with Jon Nelson
Q: Did you try transcranial magnetic stimulation (TMS) as a treatment, and what happened with that?
He explains starting TMS during a residential program, feeling initial hope as it seemed to help, but facing insurance denials and eventually no lasting relief.
Ep154 "Can a Depressed Brain Find Its Way Out?" with Jon Nelson
Q: Okay, Jon, so you have always been a people guy, super enthusiastic and so on. At some point in your life, you started realizing that you were in a funk. Tell us about that experience, about realizing that and about what this was like for you.
Jon describes a sudden, disorienting shift from a high-energy, extroverted life to a persistent funk that drained motivation, strained family life, and made him question his identity, ultimately recognizing it as depression rather than just a temporary mood.
Ep153 Can You Unlearn Anxiety? with Judson Brewer
Q: Explain to us what cognitive behavioral therapy is and how it relates to treating anxiety as a habit?
CBT aims to catch maladaptive thoughts, check their validity, and change them. Brewer explains that while CBT helps, his approach reframes anxiety as a habit driven by reinforcement learning, emphasizing attention to the body and the habit loop rather than purely cognitive change.
Ep153 Can You Unlearn Anxiety? with Judson Brewer
Q: Okay, Jud, so when somebody walks into your office and says, I have anxiety, what does that mean?
Anxiety can mean different things for different people, but it's often described as fear of the future. The core idea is that the brain simulates possible futures and can get stuck looping on them, which perpetuates worry.
