In this episode, my guest is Nolan Williams, M.D., a triple board-certified psychiatrist, neurologist and professor of psychiatry and behavioral sciences at Stanford School of Medicine. He is also the Director of the Stanford Brain Stimulation Lab. We discuss clinical applications for brain stimulation, behavioral protocols and novel drug treatments to halt and reverse mental health disorders, including depression and post-traumatic stress disorder (PTSD). We first discuss the neural circuits for self-identity and mood and stress control. We discuss Dr. Williams’ work using transcranial magnetic stimulation (TMS) to depression, trauma, PTSD, and other mood disorders. We then dive deep into the history, biology, modern use, and safety margins of the various psychedelics, including MDMA, LSD, ketamine, ibogaine, ayahuasca, and psilocybin, as well as cannabis and the use of SSRIs in both adults and children. Finally, we discuss behavioral treatments for mental health disorders, including sleep and sleep deprivation, light exposure, exercise, and training to control the brain-heart-rate pathways. Regardless of age, all those interested in mental health should benefit from the incredible breadth and depth of Dr. Williams’ knowledge and the clarity with which he conveys that information.

Dr. Nolan Williams shares his research on depression and mood disorders, focusing on the use of transcranial magnetic stimulation (TMS) and other experimental treatments such as ibogaine, psilocybin, MDMA, cannabis, and DMT. They discuss the history of each drug and their current status for clinical use and legality.
Researchers are investigating a direct link between the areas of the brain related to emotion and heart rate, to understand and better treat depression, which can be as disabling as suffering from a heart attack.
This podcast episode discusses the link between dorsolateral prefrontal cortex stimulation, heart rate deceleration, and alleviating symptoms of depression, questioning why this is the case.
The connection between heart rate and depression lies in the body's ability to regulate its own nervous system, rather than the actual heart rate itself. While a lower heart rate is not necessarily protective against depression, there are other ways to slow one's heart rate down through techniques like exhale-emphasized breathing or deliberately slow cadence breathing.
Researchers have identified a specific area in the brain involved in the cognitive control of hypnosis, the left dorsal lateral prefrontal cortex, and found that inhibiting this area leads to an increased susceptibility to hypnosis.
The overactivity of the anxiety-generating conflict-detecting cingulate in depression generates spontaneous and semi-volitional content that could also, surprisingly, create a present moment sort of experience in contrast to the perceived stressfulness of living with depression.
Scientists performed a study to investigate the effect of opioid properties of Ketamine on the Antidepressant Effect. They went on to research how Mood Regulation has a connection with the Opioid receptors.
Turning brain regions on can help in treating depression more than just relying on drugs that block the reuptake of serotonin to combat the widely held, but possibly incorrect, theory that the central issue with depression is a lack of serotonin.
The highly plastic state induced by psychedelics such as Ibogaine and MDMA may have therapeutic effects, as memories are reconsolidated and broader areas of the brain become co-active. Purity and sourcing is key for clinical trials, as contaminants like methamphetamine can have neurotoxic effects.
Psilocybin's therapeutic effect may be linked to the idea of "letting go," where patients allow themselves to assume a state they've been fighting the whole time, allowing a new perspective to overcome negative thoughts and memories. This theory is particularly relevant to patients with depression, addiction, or OCD, as well as anyone seeking psychological relief through psilocybin therapy.
The speaker emphasizes the importance of talking about mental health and normalizing conversations around it, instead of ignoring it due to societal pressures.
A straight scientific examination of psychedelics today would lead to the conclusion that they are a huge breakthrough in psychiatry with the ability to combine the benefits of SSRIs and psychotherapy. While it is important to approach their use with caution, there is a need to recognize the therapeutic potential of these substances.
The likelihood of cannabis causing or treating psychosis depends on the proportions of CBD to THC. High doses of THC have been linked to pro-psychotic symptoms but it is not clear if cannabis can be considered bad for people overall.
Dr. Jennifer Martin discusses the relationship between sleep and mental health, including the impact of sleep deprivation on depression and the effects of alcohol on both sleep and mental health.
This podcast episode explores the different types of neuromodulation therapy and their therapeutic potential for treating sleep disorders. Devices such as transcranial magnetic stimulation and transcranial direct current stimulation can provide targeted stimulation to specific brain regions to ultimately improve sleep quality.
A new technique has been developed to send memory signals into the brain and "take it out of the hippocampus's hand" for those with serious memory impairments. By using a high-powered magnet, trials are taking place in which real versions of the signals are being tested, helping to improve memory access and concentration.
