That airport traffic control tower that's in our hypothalamus, it actually is connected to the rest of your brain and the rest of your body through the hypothalamic pituitary adrenal axis and the autonomic nervous system. Consider it the airport traffic control tower of your brain.
And we go into the brain, and we can expand this bit of the brain here, the hypothalamus. This is the pituitary gland here. This would be the optic nerve connecting to the eyes.
But the other thing that caffeine does is that it stimulates more neural activity in the brain. And when your pituitary gland notices this increase in neural activity, it thinks that there's some sort of an emergency happening. And so it triggers your adrenal glands to start releasing adrenalin.
You have in your midbrain, hypothalamus and pituitary gland. And the pituitary gland is sending out messages to all the other target glands of the endocrine system.
exploded the pistachio, and we know all the molecules, and you can buy them and maybe even mix them together to create your own pistachio. The other one's the pituitary gland, and that's sitting in our bloodstream.
It's 1 out of 4 or 5 women have that disease. And it's a miscommunication between the hypothalamus and the pituitary gland and the ovary. And so you don't end up ovulating or menstruating.

Number one, how many of you people have injured your musculoskeletal system and waited to see if it will go away and heal? The moment the woman gets hit, the pituitary gland shuts the progesterone off.
So empathy is part of gaining power. This is your stress system, the hypothalamic pituitary adrenal axis.
Because what happens is if the amygdala sees that there's a tiger on the loose, all of a sudden the amygdala can communicate with the hypothalamus, which communicates with the pituitary gland that talks to the adrenal gland. And all of a sudden the adrenal gland is spitting out cortisol and epinephrine.
And we're just going to go through the parts. You have in your midbrain, hypothalamus and pituitary gland. Think of them like the person who listens to the voice mail and then the switchboard operator.
Getting angry, even just irritated, getting nervous about something, feeling depressed, feeling ashamed or inadequate or alarmed in any way, shape, or form triggers the fight/flight response systems through the sympathetic nervous system and HPAA stands for hypothalamic pituitary adrenal axis; the endocrine system in other words, because the nervous system and the endocrine system work together in terms of stress response. It's pernicious.
It sends a signal through the vagus nerve up into the chest, through the neck, up to the brain. And it tells your brain, the hypothalamus and the pituitary glands, tells your brain to release the hormone oxytocin. Now I'll bet a lot of you have heard of oxytocin because it's often labeled the hormone of love and affection and empathy.
And while we were doing that, we were assessing the peripheral manifestations of these two principal stress response systems in the human brain, the cortisol system, which is the hypothalamic pituitary adrenocortical axis, which is responsible for the output of the stress hormone cortisol. It is this powerful stress hormone that has major effects on the immune system all over the body, the cardiovascular system.
So empathy is part of gaining power. When you see danger in the world, the amygdala triggers act as a signal to the hypothalamus, goes to the pituitary glands, drops
He's led on to the valley floor by an attendant. And the thinking is that he has what's called acromegaly, which is the condition caused by a benign tumor on your pituitary gland that causes overproduction of human growth hormone.
And one of them, you had to take off the top of the skull to weigh the brain and so forth. But also, one of the teaching hospitals in London had a-- not a scam going, but an arrangement that if people like me would remove the pituitary from the back of the brain and put them in a jar, for every 100 pituitaries you got, you'd be given, I think, five pounds or something.

So I became, as a consequence of that, reasonably knowledgeable of the human skull, although not of these
