Includes: Theoretical Considerations, Psychophysiological Networks, Benefits of Psychophysiological Coherence and its Measurement, A Typology of Psychophysiological States, how vagal afferent traffic inhibits pain perception and affects cognitive performance, difference between respiration and positive, emotion-driven coherence and the heart's roles in emotional experience and processing.  More info »

The Psychophysiology of Positive Emotions and Optimal Functioning
This scientific monograph gives an overview of the physiological correlates of positive emotions and personal performance. The heart's association with positive emotions, wisdom and intelligence is central to most cultures, and now the latest research offers scientific validation for this relationship. Steps and applications of HeartMath’s Freeze Frame® and Heart Lock-In® techniques are provided to help engage the heart in transforming stress and sustaining coherence.  More info »

Bioelectromagnetic Interactions Within and Between People
A fascinating monograph that explains the bioelectromagnetic interactions in and between people. Did you know your physiological systems constantly interact with each other in subtle ways, that the electromagnetic signal produced by your heart is registered in the brain waves of people around you? Discover why scientists believe the heart's electromagnetic field acts as a central synchronizing signal within the body and a carrier of emotional information.  More info »

Changing Your Emotions – a New Approach to Stress Management
Until recently, stress research and treatment has largely derived from a belief that mental processes alone govern or activate the stress response. This scientific monograph explains in layman’s terms the latest stress research showing that emotions, more than thoughts, activate the physiological changes comprising stress responses. It describes how HeartMath’s simple tools engage positive emotions to permanently self-manage stress and break the cycle of recurring negative emotional patterns.  More info »

The Central Role of the Heart in Generating and Sustaining Positive Emotions
Learn about the science behind heart coherence, the psychophysiological state marked by calm, emotional balance and alertness that improves cognitive capability for problem-solving, decision-making, long-term memory and more. It explains the heart’s role in the emotional process and how intentionally experiencing positive emotions such as care, compassion and love can help you achieve heart coherence.  More info »

Neurocardiology: Anatomical and Functional Principles
This technical monograph discusses the heart’s intrinsic nervous system, also known as the "heart brain." The anatomical organization and function of the intrinsic cardiac nervous system and its complex neuronal processing and memory capabilities  are described. Learn how the heart brain, independent of the central nervous system, can process information and make decisions about its control.  More info »

The Making of Emotions
Explore recent scientific advances that clarify a number of central controversies in the understanding of emotion, including the relationship between intellect and emotion. A discussion of the critical role of ascending input from the heart and body to the brain in the generation of emotions culminates in a detailed presentation of a new model of emotion in which the brain functions as a complex pattern-matching system.  More info »

Both the layperson and science professional will appreciate its simplicity and thoroughness.  More info »

Exploring the Human-Earth Connection
Classical physics for millennia has defined reality as a vast array of solid objects separated by empty space. Scientists today, however, suggest an unseen thread ties all things together, what the authors of the 34-page e-book call a “holistic web of interconnectedness.” They explore the emerging field view of reality and the four central hypotheses that drive HeartMath’s Global Coherence Initiative research, including that Earth’s magnetic fields carry biologically relevant information that connects all living systems. You’ll learn about the potential for increasing collective consciousness as people begin to better perceive their personal biofields and manage the energy they radiate  More info »
