How YourBrain Worksa 200-million-yearsuccess storyLoretta G. Breuning, PhD
Humans inherited brain structuresfrom earlier animals and added on.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
You have 3 brainsLoretta Graziano Breuning, PhDInnerMammalInstitute.org
They’re all goodEach of your brainshas successfullypromoted survivalfor millions of years.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
They promote your well-beingby working togetherLoretta Graziano Breuning, PhDInnerMammalInstitute.org
Each brain seeks in survival its own wayhumanmammalreptileLoretta Graziano Breuning, PhDInnerMammalInstitute.org
The mammal brainseeks survivalthrough social bonds.The reptile brainseeks survival byreacting to threats.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
The human cortexseeks survivalby learningfrom experience.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Working together,your three brains use experienceto build social bonds and avoid harm.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
But it’s not easy.Your three brains are not on speaking termsbecause the animal braindoesn’t think in words.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
It thinks by releasing neurochemicalsinto the body. Humans experiencethese chemicals as emotions.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
When the animal brain sees somethinggood for survival, it releases chemicalsthat humans experience as a Graziano Breuning, PhDInnerMammalInstitute.org
Something bad for survival triggerscortisol in the animal brain.Humans perceive it as anxiety.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Neurochemicals are powerfulenough to trigger urgent survivalbehaviors in the state of nature.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Our neurochemical responses are hardto put into words, but it’s easy to seethe behaviors they trigger in animals.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Your human cortex learnsabout survival from experience.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Experience builds real physicalpathways in your brain.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Your cortex builds pathways in 2 ways:from emotion and from repetitionLoretta Graziano Breuning, PhDInnerMammalInstitute.org
Emotion instantlyimproves a neuron’sability to triggeranother neuron.Loretta Graziano Breuning, PhDRepetition graduallyimproves a neuron’sability to triggerother neurons.InnerMammalInstitute.org
Your brain can “learn” behaviors thatare not really good for your survival.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Your animal brain seeks whatever feltgood in your past.Your cortex may think it’s not good foryour future.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
The electricity inyour brain flowslike water,finding the paths ofleast resistance.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
Electricity easily flows into pathways builtfrom past emotion and repetition.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
You can create new neural pathwaysby repeating new experiences.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
But it’s not easy.The more you know abouthow your brains works,the better you can promoteyour own well-being.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
200 million years ago,mammals began evolving brain systemsthat support group life.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
More of their babies survived as a result,and the successful brains got passed on.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
You have inheritedthe brains of successful survivors.Loretta Graziano Breuning, PhDInnerMammalInstitute.org
