Each neuron in the brain sends signals to 1,000-10,000 of it's nearest neighbors about 200 times per second. So what are they chatting about?
Neuron1: Hi, what's your name?
Neuron2: I'm Neuron2 of the Amygdala region. What's your name?
Neuron1: I'm Neuron1 of the Thalamus region. Nice to meet you.
Neuron2: Nice to meet you, too. What's that you're reading?
Neuron1: I'm reading Chromosome 21, chapter 11, verse 4. It says to watch for two circles, and notify anyone who's interested when I see them.
Neuron2: I'm certainly interested. Please let me know when you see that pattern.
Neuron1: I'm seeing it now, actually.
Neuron2: Really? Can you describe it?
Neuron1: Let me ask my cousin, Neuron3.
Neuron2: OK, I don't mind waiting.
Neuron1: (pause) Neuron3 reports the two circles are compressed, more like slits really. And there are some furrowed lines between them.
Neuron2: Oh, my! I've been reading Chromosome 13, chapter 3, verse 5. It tells me that if I see two slits with furrowed lines, I need to sound the alarm!
Neuron1: I'm glad I could help. Let me make an RNA note of our conversation. I'm so forgetful otherwise. If it's important, I'll store it in my DNA.
Neuron2: It could be nothing, but I'll let you know! Gotta run now. Let me know if anything changes!
Neuron1: Will do! TTYL!
