As the author of Neurotransmitters in Transformational Learning: A Neurobiological Perspective on Profound Change, I am both humbled and excited to present this work, which represents a confluence of two dynamic fields: cognitive neuroscience and transformational learning. My journey into this interdisciplinary exploration began with a fascination for the profound moments of personal and intellectual transformation that reshape how individuals perceive themselves and their world. These moments, often sparked by a disorienting dilemma or a powerful insight, are not merely psychological or pedagogical phenomena, but are deeply rooted in the intricate workings of the human brain. This realization inspired me to bridge the gap between the established theories of adult education and the rapidly advancing insights of neuroscience, with a particular focus on the role of neurotransmitters-those remarkable chemical messengers that orchestrate our cognitive, emotional, and behavioral lives.
