TRANSCRIPT: 

Thank you everyone.

I have brought for you a human brain. So this is a real human brain. And when I look at this brain, I am reminded that we are neurocircuitry. We are neurocircuitry, and every ability we have — we have because we have cells that perform that function.

We know more about the human brain than we’ve ever known before. And we’ve learned things in the last 10 to 20 years — most of your life span — that has completely shifted the way neuroscientists think about this organ and our relationship with it.

When I was in school back in the ‘80s, we were taught that the brain cells you were born with are the brain cells you’re going to die with, and you are not going to get anymore along the way. We do know that our brain is capable of growing some new neurons, and this is neurogenesis.

We are capable of growing new neurons, particularly in response to trauma. In addition, neuroplasticity is the ability of our brain cells to rearrange who they are communicating with. What this means is that the brain you walked in with this morning, is not identical to the brain that you are going to take home with you tonight.

In addition, we understand that we are capable of mindfulness. Mindfulness is our ability to observe the neurocircuitry we are running inside of our heads. But on top of simply observing our neurocircuitry, we are capable of changing our thoughts and changing our brain. We have the ability to pick and choose what’s going on inside of our heads.

So we typically run three types of neurocircuitry. We think thoughts, we stimulate emotions and feel emotions, and we run physiological responses to what we are thinking and what we are feeling. I have the ability to think a thought, stimulate an emotional circuit, and then run a physiological response to what I am thinking.

From the moment I think a thought that stimulates my anger circuit, to the time that I run my physiological response where I dump noradrenaline into my blood stream, it flushes through me and flushes out of me. From the beginning of the thought, to the time where my blood is clean of that chemistry, takes less than 90 seconds. And I call this the 90-second rule.

Now, how many of you have the ability to stay angry for longer than 90 seconds? What you are doing, is you are rethinking the thought that is restimulating the anger circuit, which is restimulating the physiological response, and we can stay mad for days.

Now the bottom line is, I am neurocircuitry. We are neurocircuitry. And my neurocircuitry is my neurocircuitry, and you do not have the ability to stimulate and trigger my circuitry without my permission. You cannot make me angry, unless I stick my trigger out there for you to pound on and stimulate my neurocircuitry. If I give you the power to trigger my neurocircuitry, then I have given you my power. And if I give you my power, then I become vulnerable to you through manipulation, through advertising, through marketing, through peer pressure and through abuse.
