Did you know?
Neurons typically fire 5 – 50 times a second, with millions and even billions of them pulsing in harmony with each other many times a second; the electrical currents of that pulsing are revealed as brain waves in an EEG.

In the half second it takes you to clap your hands, billions of synapses have activated in your brain.

Most brain activity is lightning fast and forever outside of awareness. The slower, more congealed turgid stuff that we call thought is just the observable tip of an iceberg of lightning quick electrical, chemical – and possibly quantum – activities.

In the deepest sleep, and even in such a deep coma that artificial life support is needed, the brain is always humming away, always “on,” with billions of neurons firing every minute, in order to keep your body alive and ready for immediate survival activities.

Consequently, your brain – about 2% of the weight of a typical person – consumes about 20% of the oxygen and glucose circulating in your blood.

She has spoken on these issues to clinicians, educators, and researchers around the world.

Her work has been featured at SxSW, TEDx, and on a wide range of media platforms including Red Table Talk, the Today Show, Oxygen, Investigation Discovery, and Bravo, and she is a featured expert on the digital media mental health platform MedCircle.

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.

He’s one of the world’s leading experts on the impact of trauma in childhood, and his work on the impact of abuse, neglect, and trauma on the developing brain has impacted clinical practice, programs, and policy across the world. His work has been instrumental in describing how traumatic events in childhood change the biology of the brain.

Dr. Perry is also the author, with Maia Szalavitz, of The Boy Who Was Raised As A Dog, a bestselling book based on his work with maltreated children, and Born For Love: Why Empathy is Essential and Endangered.
