Comment on TED- Ed: The Genetics of Depression- Deon by deon

Hello Sam,
Thank you for your thoughtful feedback!
Aside from genetic and psychological factors, major life events or experiences may also affect depression. However, by major life events it also includes that of positive ones. Such as moving into college, getting married, childbirth etc. Although such events seem to have a positive impact on the person, big changes like these can lead to depression due to the unfamiliarity of these events. Depression can also be influenced by how you were raised as a child. So if you grew up with close relatives suffering from depression, as a child you may view these symptoms as normal and eventually start behaving so.
That’s the best answer I can give, hopefully your question is answered!
Again, thank you for your comment!

Thank you very much for your comment.
That is a great question Jason. Although study shows that rats (a social animal) with damaged hippocampi withdrew from social interactions, this does not directly connect to depression. It is a peculiar result seeing that rats usually interact with other rats. However, it’s more likely to say that this information suggests a relationship between hippocampus volume and social interaction, rather than social interaction and depression. In other words, just because an organism has a lack of social interaction does not mean that they have depression. Simply because this species might not be social at all. All of the animal- related depression studies still does not have a solid conclusion that animals even have depression at all.
I hope this answers your question, thank you for your feedback Jason!

Hi Yuwen, thank you for your feedback!
To answer your question, ketamine has been found to increase stress resilience in rats. And this effect seemed to be long term as well. However, ketamine has not been tested on humans regarding to depression or other mental illnesses yet, so we do not know how the scientists are working to avoid substance abuse. Repurposing ketamine as a cure to depression is a very new concept and much of the research has not been done yet. For more information check out this TED talk:
Thank you for your comment Yuwen!

Thanks, Yuwen!

“Yuwen” all the others have really cheered me up with your comments! (Get it?)

As for your question, the concept wouldn’t cause students’ brains to implode. It is confusing though, and I’ll try to explain it here. I’m pretty sure there’s a part of quantum mechanics which states that particles sometimes appear randomly, one matter, one antimatter. These particles immediately destroy each other upon creation.
As for its relation to heavy elements, I’m going to quote my source here, as I personally find it hard to explain this. This is gonna be long.

“It turns out that the innermost electrons of element 173 might be in an unusual, unstable state that can evoke these “virtual” particles.
If one of these electrons gets kicked out of its shell, for example by zapping it with an X-ray, it will leave a hole behind. This hole will be filled by an electron that appears out of nothing. But for this electron to form, a positron must also form, and this will be emitted by the atom.
In other words, the electron clouds of these really huge elements might occasionally burp out particles of antimatter.”

Here’s my source, the quote is from the bottom of the article. My Source

Hope that helped you. I sorta get it, but I’m still a bit confused about it myself.

Thanks, Michelle! I really thought my TED talk was bad, but you’ve considerably cheered me up. In response to your comment, I’ve made a few… modifications to the post.
Good question about the particle accelerators. I know that they were invented in the early 1930s, so I assume scientists have been using them since then.
The first element to be synthesized was technetium, and that happened in 1937. So saying it was in the 1930’s is a safe bet.



Comment on TED Talk – Placebos by phia

Hi Sam! In regards to your question, there have been studies similar to what you’re talking about. In a study, one group was given nothing, the second group was given a placebo prescription but no other added care and attention, and the third group was given a placebo and had regular interactions with a doctor to check in with how they were doing. The second group improved more than the first, but the third group improved most. This is believed to be because they were being cared fore more than the second group, that only received a prescription but nor further care. So yes, I do think that he placebo effect can be heightened through the delivery of the message.
