You know how oil and water don't mix. Something like that is how life came to be.

Basically, something got energy, the energy spread out, created order, and the most convenient way for it to spread is by life eating stuff

All the energy of your body likely came from the sun.

Life is nothing more than a really good solar powered engine.

I agree that emotions are far more abstract than anything a single-celled organism experiences, but I tend to think they are basically super-complex versions of sensations, involving far more neurons.

I love mathematical elegance, and the math behind life is gorgeous.

I would love to know more about the math behind life.

😄

Emotions are only slightly caused by neurons.

Is cortisol a neuron?

I love the math behind physics, and any science has elegant math that can blow the mind.

How about adrenaline?

Testosterone?

Cortisol and adrenaline affect neurons, no? Else they would be less relevant to emotions, right?

You are citing neurotransmitters.

Affect and caused by are different.

And, I'm citing hormones.

Right. Neurotransmitters, which are certain types of hormones, right?

Like adrenaline and testosterone

No, different system. Endocrine system.

how is dik make hard

... What?

Okay, so noradrenaline and norepinephrine, for example, are neurotransmitters, while adrenaline refers to the hormone. I just looked it up. Is this right?

Adrenaline-epinephrine

=

man i'm hungry

Oh, noradrenaline IS norepinephrine, isn't it?

No. Your adrenaline glands are right above your kidneys.

Yes, I knew where the adrenal glands were.

Which isn't in your brain.

So for something to be a neurotransmitter, it has to be produced in the brain?

Hormones are too big to enter the brain. It's called the blood brain boundary.

In the brain or nervous system. For example, serotonin is in the nerve ganglia of the gut.

Okay

Hormones are too big to enter the brain. They act on other organs.

So how is the neurotransmitter noradrenaline related (if it is) to adrenaline?

Complex explanation. Simple one is hormones do things that make your body feel different. You feel this and interpret it as emotions the same way your brain turns photo sensetive chemicals in the eyes to sight.

Like when your anxious, you know you're anxious because your stomach tenses up, your heart speeds up, etc

Right.

You know you're hungry because your stomach feels empty.

When I'm anxious, my thoughts race too.
