Four Books in Print Two #1 International Bestsellers

Four decades at the intersection of neuroscience, psychology, and the healing potential of the brain.

Brant Cortright, Ph.D. spent his career as a professor and clinical psychologist at the California Institute of Integral Studies in San Francisco — one of the foremost institutions for integral and transpersonal psychology in the world. His work sits at a rare crossroads: rigorous neuroscience, clinical depth psychology, nutritional research, and a spiritual dimension that most brain health books ignore entirely.

His books span two distinct bodies of work. The brain health series — from the breakthrough Neurogenesis Diet and Lifestyle through to the revised Radiant Brain Health — translates leading neuroscience research into practical guidance for anxiety, depression, and cognitive decline. His earlier transpersonal psychology works examine the spiritual dimension of healing at depth, bridging Eastern and Western approaches to the psyche.

"Your rate of neurogenesis is key to feeling good or bad, vibrant and rejuvenated or stagnant and depressed. Brain health is key to health in every area — physical, emotional, mental, spiritual."

The brain has a remarkable capacity to heal and grow at any age — but it requires the right conditions. Ask me about the ideas in the books: neurogenesis, the four dimensions of brain health, the neurotoxic environment, or what the research suggests about anxiety, depression, and cognitive function. All answers are educational explorations of published ideas, not clinical guidance.
