7: 09 Pain is not a benefit. Pain is so bad that it is itself hurting. There wouldn t be any word like hurt if there was no pain. By that kind of evolutionary reasoning pain should be able to be kind of switched of or ignored when there is no chance of removing the threat or what is causing the damage. But there isn t because evolution doesn t care about you. What may actually be a fair point though, although it wasn t raised, is that pain tolerance may be an evolutionary advantage. The causes she mentioned essentially indicate how vulnerable you are and the more vulnerable you are the more dangerous anything which can cause pain is.

Great video! Would love to see more on neurology.
I had a recent visit to the dentist that required local, and the injection hit a nerve in the lower right quadrant. it felt like lightning in my face and head. And ever since, even just a light touch to my chin will send an echo through my lip and gums. It's bizarre! I wish I could get some scientific explanation on that.

7: 00 That's literally not true. Meta analysis of acupuncture research has consistently shown acupuncture to be ineffective as anything other than a placebo. Some biased researchers have tried presenting their data as if it works by including sham-acupuncture as if it's acupuncture. Acupuncture is pure pseudo science.

31 pairs of spinal nerves. how many fibers in each?
Is digestion caused and regulated by brain cells?
Does the brain decide went to replace 6 yo heart muscle cells? .by sending macrophages to kill them?
Red blood cells get replaced, 3 million per second 24 / 7. do neurons play a role?

Why does the camera cut so much on zoom in and zoom out. Drives me nuts. I understand when it has to in order to cut down on information but zoom in and out after every sentence? Drives me nuts. Every video.
Great and fun info otherwise but I can't stand the camera

Oh man I've gotten brain zaps when stopping medication it's horrible. It feels like a weird electricity (btw I only stopped the medication when the pharmacy wouldn't fill the prescription on time due to the insurance company)
reply

In Dutch it's (literally translated) telephone bone. I always liked that name, it does feel like electricity surging through after hitting it if you ask me.
But, I can't deny a good dad-joke, so funny-bone is pretty nice too

reply

at least twice ive hit my funny bone and started laughing uncontrollably until i was sore and after i couldnt breath. I always thought THAT was why its called the funny bone and that it was a reflex like when you tap your knee
reply

She was helpful, but I didn't learn ANYTHING as I already knew these. Who's writing these questions? can you like, next time pick better questions, I mean, these are questions we knew back in school
reply

In German the funny bone is called the Musikknochen (music bone) which is pretty fitting imho, because people tend to kinda sing when they hit it: D
reply

The tickling question - But where on the brain lights up when you're tickled and you feel panic or anger? ZERO park of being tickled makes me laugh.
reply

I'm currently taking a molder dysfunction and control class this semester and it is so fascinating to learn how our brain can mediate movement
reply

What do you mean when you say ''Not remembering anything'' in regards to general anesthesia? What is there to remember? Am I not unconscious?
reply

In German, the funny bone is called Musikantenknochen which translates to musician s bone. I guess because it makes you sing when you hit it.

I'm not saying she's brilliant at explaining everything, but after watching this I went to get the mail and I received a diploma.
