• Shaped by evolution, especially of emotional and relational capacities; for example, the bigger the primate social group, the bigger the brain
• 3 pounds, 1.1 trillion cells, including 100 billion “gray matter” neurons
• Always “on” – 2% of the body’s weight uses about 25% of its oxygen
• Average neuron has about 1000 connections (synapses), 100 trillion in all
• Synapses fire 1 to 100 times a second; quadrillions of synapses activate each minute
• Brain regions linked by neural pulses synchronized within a few milliseconds
• Highly interconnected network full of circular loops: awareness of awareness…
• Number of possible brain states: 1 followed by a million zeros
• The most complex object known in the universe
• Both temporarily, in electrochemical waves lasting mere milliseconds, and permanently, as existing synapses get strengthened and new ones get made
• As circuits get used, they strengthen their connections; “neurons that fire together, wire together.” Your experience matters, leaving an enduring trace behind.
• London taxi drivers have thicker regions that create visual-spatial memories.
• Mindfulness and concentration meditations activate different parts of the brain.
• Brain activity generates mental activity (mostly forever outside awareness).
• Trauma shrinks the hippocampus, which becomes less able to create new memories.
• More active left frontal lobes foster positive emotions.
• Trigger patterns of neural pulsing that produce relaxed alertness
• Activate positive emotion circuits, building resilience and resistance to depression
• Increase serotonin, a neurotransmitter that supports mood, sleep, and digestion
• Thicken the anterior cingulate, strengthening attention and self-observation
• Thicken the insula, strengthening internal sensing and empathy for others
• Stimulate the parasympathetic nervous system (PNS) for relaxed well-being
• Strengthen the immune system, improve cardiovascular health, dampen chronic pain
• Establish frontal lobe direction through forming an intention for your meditation.
• Activate the relaxing PNS through full exhalations, relaxing specific muscles, etc.
• Reduce external vigilance by evoking a sense of safety and security
• Increase concentration (and support motivation) through opening to and even calling forth positive emotions such as gratitude, happiness, contentment, or tranquility
• Register wholesome experiences in emotional memory by savoring them
• Encourage release of self through giving up conscious control of breathing
• As needed, increase stimulation by sensing the whole body breathing, walking, etc.

Dr. Stephen Porges is a Distinguished University Scientist at Indiana University, Professor of Psychiatry at the University of North Carolina, and Professor Emeritus at both the University of Illinois at Chicago and the University of Maryland. He is a former president of the Society for Psychophysiological Research and has been president of the Federation of Behavioral, Psychological, and Cognitive Sciences, which represents approximately twenty-thousand biobehavioral scientists. He’s led a number of other organizations and received a wide variety of professional awards.
In 1994 he proposed the Polyvagal Theory, a theory that links the evolution of the mammalian autonomic nervous system to social behavior and emphasizes the importance of physiological states in the expression of behavioral problems and psychiatric disorders. The theory is leading to innovative treatments based on insights into the mechanisms mediating symptoms observed in several behavioral, psychiatric, and physical disorders, and has had a major impact on the field of psychology.
Dr. Porges has published more than 300 peer-reviewed papers across a wide array of disciplines. He’s also the author of several books including The Polyvagal Theory: Neurophysiological foundations of Emotions, Attachment, Communication, and Self-regulation.
