Waking Up Your Spiritual Brain: Part 1
Psychologist Lisa Miller presents scientific research showing that spirituality is an innate human capacity with measurable neural correlates that protect against mental illness, depression, and suicide. She argues that sustained spiritual practice—prayer, meditation, service—literally thickens the cortex in brain regions associated with transcendent awareness and that spirituality and depression are two sides of the same coin.
Summary
Host Shankar Vedantam interviews Dr. Lisa Miller, a Columbia University psychologist, about her 30 years of research on the neuroscience of spirituality. The episode opens with Thomas Hood's poem about losing childhood wonder and explores whether that sense of transcendence can be recovered in adulthood.
Miller recounts formative experiences from her clinical work. She describes treating Ileana, a 12-year-old girl traumatized by her father's murder, who experienced a breakthrough after her family held a Dominican spiritual ceremony honoring her deceased father. When Ileana subsequently met a boy with her father's unusual name at a school dance, she interpreted this as a sign that her father was watching over her—a spiritual understanding that dramatically improved her psychological state after conventional therapy had stalled.
Miller also describes organizing an informal Yom Kippur service on a psychiatric inpatient unit despite institutional resistance. The service had remarkable effects: a typically explosive patient became a spiritual leader, guiding the prayers; a depressed woman realized she could be forgiven; and all participants experienced profound peace. A Catholic patient later asked Miller to pray with her before being transferred to another facility, demonstrating how spiritual support transcended denominational boundaries.
Miller explains that she witnessed similar spiritual illumination in the subway—an Orthodox Jewish man davening (praying) with bright, joyful eyes—contrasting sharply with the widespread low-grade depression (dysthymia) she observed in her peers and in society. She and her partner, despite achieving success as a lawyer and psychologist respectively, experienced this same dysthymia—a feeling that achievement-focused lives lacked meaning.
Miller describes the scientific basis of her research: using MRI studies, she identified four neural circuits involved in spiritual awareness. The first quiets the default mode network (similar to mindfulness); the other three comprise the "awakened brain." These are: the bonding network (feeling loved and held); the ventral attention network (shifting from narrow, anxious focus to broad openness and guidance); and the parietal region (recognizing oneself as both distinct and interconnected with all life). Importantly, these circuits activate identically across all faith traditions and in non-religious spiritual practitioners.
Miller's research shows that spiritual capacity is one-third innate and two-thirds environmentally formed—highly malleable through practice. When people sustain a strong spiritual life over time, their cortex thickens in these same brain regions—the exact regions that show reduced thickness in people with recurrent major depression. This suggests spirituality and depression are neurologically opposite states.
Miller presents major protective findings: adolescents with strong spiritual lives are 82% protected against completed suicide and 80% protected against addiction onset. She distinguishes spirituality (innate capacity for transcendent relationship, universal across traditions) from religion (environmentally transmitted, culturally specific), noting that bad acts done in the name of religion are inconsistent with natural spirituality's core operating principle: being loving, guiding, and never leaving anyone alone.
Miller discusses the resistance her work has faced from the scientific and medical establishment. Early in her career, a supervisor told her never to mention the Yom Kippur service on her resume—spirituality was seen as incompatible with scientific medicine. However, by carefully embedding one spiritual variable into otherwise methodologically conventional studies using familiar datasets and peer review, she published approximately 200 peer-reviewed articles in top journals. Despite rigorous science, initial responses were confused silence; younger generations of researchers and clinicians have shown greater openness to exploring spirituality.
Finally, Miller contrasts two modes of consciousness: achieving awareness (strategic, planning-oriented, how we're trained in school) and awakened awareness (intuitive, receptive, guided by perception of what life is showing us). She argues both are necessary—awakened awareness sets our direction (North Star), while achieving awareness executes the plan. Contemporary culture overemphasizes achieving awareness, leaving people strategically competent but directionless.
About this episode
Food, safety, and strong relationships are essential to our survival. Psychologist Lisa Miller says our brains also crave something else: transcendence. She suggests that spirituality is a universal human capacity, and that feeling connected to something larger than ourselves may be essential to a fulfilling life.
Key Insights
- Lisa Miller found that adolescents with strong spiritual lives are 82% protected against completed suicide, the leading cause of death in Gen Z, suggesting spirituality operates at a scale of protection comparable to pharmaceutical interventions.
- Miller identified four discrete neural circuits that activate during spiritual experience: the default mode quieting network, the bonding network, the ventral attention network, and the parietal region—circuits that activate identically regardless of the person's religious tradition or non-religious spirituality.
- Miller argues spirituality is one-third innate and two-thirds environmentally formed, meaning spiritual capacity is highly developable through practice such as prayer, meditation, and service, unlike fixed traits like IQ.
- Miller's research shows that sustained spiritual practice literally thickens the cortex in the exact same brain regions that show reduced thickness in people with recurrent major depression, suggesting spirituality and depression are neurologically opposite states.
- Miller distinguishes spirituality (innate capacity for transcendent awareness, universal across all traditions) from religion (environmentally transmitted, culturally specific), and argues bad acts in religion's name indicate inconsistency with natural spirituality's core principle of being loving, guiding, and never leaving anyone alone.
- Miller developed a strategy to publish spirituality research in top peer-reviewed journals by embedding one spiritual variable into otherwise methodologically conventional studies that used familiar datasets and statistics, allowing approximately 200 publications despite initial institutional resistance.
- Miller describes two modes of consciousness—achieving awareness (strategic planning, how schools train people) and awakened awareness (intuitive, receptive perception of what life is showing)—and argues contemporary culture over-develops achieving awareness while neglecting awakened awareness that provides life direction.
- Miller's breakthrough with patient Ileana demonstrated that spiritual interpretation of events (meeting a boy with her deceased father's name after a family ceremony) produced psychological recovery where conventional trauma therapy had failed, suggesting spiritual frameworks can facilitate healing in ways standard psychotherapy cannot.

This is Hidden Brain. I'm Shankar Vedanta. Thomas Hood was a 19th century English poet known for his elegant, often melancholy verse. His 1826 poem, I Remember, I Remember, captures a feeling that is familiar to many adults, especially its wistful last lines. I remember, I remember, the fir trees dark and high. I used to think their slender tops were close against the sky. It was a childish ignorance, but now there's little joy to know I'm farther off from heaven than when I was a boy. Thomas Hood's poem gestures to the reality that as grown-ups many of us lacked the effortless sense of connection and awe that we felt as kids. Was that intimate bond with the…

Stepping Out of the Shadows
The episode explores the concept of negativity bias and disgust, emphasizing how our brains prioritize negative experiences over positive ones. Psychologist Allison Ledgerwood discusses how focusing on the negative shapes our perceptions and responses, while David Pizarro analyzes the nature of disgust and its cultural implications.
A Secret Source of Connection
This Hidden Brain episode explores the psychology of kindness and human connection, examining why people fail to extend help despite wanting to, and why feeling seen and valued is essential to human well-being. Psychologist Amit Kumar's research reveals that givers systematically underestimate the impact of their kind acts, while psychologist Gordon Flett explores how the human need to 'matter' affects physical and emotional health.
Who Are You, Really?
This Hidden Brain transcript covers two main topics: Eric Oliver's exploration of the self as a multifaceted, ever-changing process rather than a singular fixed identity, and Scott Barry Kaufman's critique of IQ testing as a narrow measure of human intelligence. Both guests argue against reductive labels and fixed notions of who we are, advocating for broader, more nuanced understandings of human potential.
Unleashing Your Creativity
This Hidden Brain episode explores the science of creativity and inspiration, featuring psychologist Ap Dijksterhuis who explains how unconscious thought processes generate creative breakthroughs. The episode draws on historical examples like Kekulé and Poincaré to illustrate how insights emerge not during intense focus but during relaxed, distracted, or sleeping states. Research suggests that setting goals and then allowing the mind to wander — rather than forcing conscious analysis — produces more creative and accurate outcomes.
The Past is Never Dead
Anthropologist Joseph Henrich joins Hidden Brain to explore how historical events, cultural practices, and institutions from centuries past continue to shape modern psychology, behavior, and even biology. The discussion covers the invention of mechanical clocks, the Catholic Church's transformation of European family structure, and the concept of WEIRD (Western, Educated, Industrialized, Rich, Democratic) psychology. Henrich argues that what we consider natural human behavior is often the product of specific historical choices made by identifiable actors with particular goals.
