#074: Know Your Neurotransmitters: Dopamine

May 01, 2015
MP3

Get ready for round two of the “Know Your Neurotransmitters” series. This week Jesse taps into Prof. John Salamone’s vast pool of knowledge on the highly popular, and often misunderstood neurotransmitter, Dopamine. We learn about RDoC (Research Domain Criteria) and smarter ways of categorizing, diagnosing and treating mental disorders in the near future.

Speaking of things to come, in the Ruthless Listener Retention Gimmick, Jesse reports on some salacious statistics about whether robots are the fetish of the near-future…

Here’s wishing you all the very best in balancing the amount of Dopamine in your brain. In the case of Smart Drug Smarts, the path of excess DOES lead to the tower of wisdom. So don’t forget to subscribe to our mailing list.

    Hi. This is a great episode. I already listened twice and would need a transcript.
    Why the choice of bupropion and the older and more easily available deprenyl (selegiline), a MAOB inhibitor?

    1. Jesse Lawler says:

      Glad you enjoyed — and actually, YES, we’re working on getting a transcript made — of this and other episodes.

      I’m not quite clear on your question, but if you can re-state it (maybe reference the piece of the interview you’re referring to?), I could ping Professor Salamone and maybe get some clarification.

        Thanks Jesse. Great to hear about transcripts!
        Regarding my question, at min 13 approx. Dr speaks about bupropion to increase dopamine and thus motivation. He also comments about SSRIs decreasing motivation. I know that bupropion increases dopamine by blocking a transporter but there are other drugs like the well known selegiline (a.k.a. deprenyl) in alife extension and smart drugs communities that are also supposed to increase dopamine, in this case by inhibiting MAOB. My question is what is the difference between the effects of bupropion and selegiline in terms of effects in motivation. If they are both effective, selegiline is easier to obtain and also has less side effects. Or is it thet bupropion has a more norepinephrine increasing effect? I hope I made my point clearer.

    There’s a great book called Compass of Pleasure by David Linden. In it, he talks a lot about dopamine, as well as the research done on mice where they’ve chemically and electrically stimulated the brain to produce a pleasure response. It would be great if you did another ‘Know Your Neurotransmitter’ episode with serotonin, maybe with David as the guest!
