Julia

Thank you for the instructions, I’ve started writing and have some questions

Today 16:42

John

Shoot! 😊

Today 16:43

Julia

Do you think I can quote some of the old texts in the article or is that too boring?

Today 16:43

John

Well, that depends. A short, punchy one-liner should be fine.

Today 16:44   

Julia

OK, here’s a few I was thinking about using:                                         

Today 16:45

Julia

“Thoughts stand in the same relation to the brain as urine to the kidneys” (Vogt,1846)

Today 16:46

Julia

“No thought without phosphorus” (Moleschott ,1852)                        

Today 16:46

Julia

“The brain creates a conscious field just as the stomach and digestive tract create digestion.” (Searle ,2005)

Today 16:47

John

Holy moly! Last one’s a bit long, but those are certainly fine!

Today 16:48   

Julia

Yeah, I was doubting that last one, but I wanted to show how we still think in those same terms about the brain and the mind  😊

Today 16:49

John

They do sound similar, but are they really the same, more than a century later?

Today 16:50   

Julia

I found someone saying literally the same thing as Searle, but it’s in French:

Today 16:50

Julia

Pour se faire une idée juste des opérations de la pensée, il faut considérer le cerveau comme un organe particulier, destiné spécialement à la produire; de même que l’estomac et les intestins à faire la digestion” (Cabanis ,1802)

Today 16:52

John

OK, that is too long and too French … my high school French is quite rusty, but that does sound like literally the same, yeah. 😊

Today 16:53   

Julia

Cabanis is basically saying that the brain produces though like the stomach produces digestion, so …

Today 16:54

John

You could just reference it, without the whole quote.

Today 16:54  

Julia

I guess that would work too.                                                                    

Today 16:55

John

Good find, those quotes are quite thought provoking. So are you arguing against progress in neuroscience?

Today 16:56   

Julia

Oh no, not at all! Just that there’s some very basic assumptions we’ve kept since the beginning. 😊

Today 16:57

John

OK, even more looking forward to your draft!

Today 16:58

Julia

Dear Sir, my professor has told me to contact you wrt an internship at your magazine

Today 16:42

John

Hello Julia! Yes, Cho told me about you. Please just call me John! 😊

Today 16:43

Julia

Hi John! So what can you tell me about the summer internship?

Today 16:43

John

We have a deal with the university where you get both paid and credit for working with us

Today 16:44   

Julia

That’s great! Just what I was looking for! 😊                                          

Today 16:45

John

Cho told me you wrote a great paper about Mind and Brain, and that is exactly what we are looking for.

Today 16:46   

Julia

I saw that your article referenced it, that was so cool!  😊                 

Today 16:46

John

Yep, but then there’s the boring part too: we need an intern to also do some basic copyediting, fact checking, and data entry

Today 16:47   

Julia

I understand that the internship is a lot of menial work too, getting to learn the ropes etc.

Today 16:47

John

Indeed, writing for a large public is different from writing essays

Today 16:48   

Julia

I look forward to your feedback and comments then!                        

Today 16:49

John

Happy to oblige! Do you already have an idea for an article?

Today 16:49   

Julia

Well, I really liked the philosophy of mind class, so now I’m looking into the history and philosophy of neuroscience

Today 16:50

John

I saw there was something of that in your essay already

Today 16:51   

Julia

Yes! Some of the early stuff is really fascinating and still very similar to what we do now

Today 16:51

John

Sounds interesting, I’ll send you a some instructions and look forward to your draft!

Today 16:52   

Julia

That’s great!  😊

Wounds of this organ … are almost as easily cured, as those of most of the other

Cho and John are talking about the following article:
Organoids to Rebuild the Brain

Cho

So which new brain-things are your going to discuss  😉                   

Today 15:42

John

Some medical technology, but mainly BCI’s

Today 15:43

Cho

BCI’s???   😯                                                                                                 

Today 15:43

John

Cho

I know what it means, I was just surprised  😄                                     

Today 15:45

John

Why? 😊

Today 15:44   

Cho

There’s a limited number of legitimate applications in medicine, like brain-controlled prosthetics, but for now it is mostly hype

Today 15:45

John

What do you mean?

Today 15:45   

Cho

Like the Neuralink, and getting a brain implant so you can change the channel on your TV

Today 15:46

John

That’s not actually how it is marketed you know … and not all BCI require surgery

Today 15:47   

Cho

Fine, I’m just a bit skeptical about it for now. 😏                                  

Today 15:47

John

That’s OK, we’re writing about the future possibilities, so we’re allowed a bit of science fiction here

Today 15:48   

Cho

So, learning stuff overnight without having to study and augmentation

Today 15:48

John

A little bit of that, but also some very different stuff

Today 15:49   

Cho

Such as?                                                                                                       

Today 15:49

John

Besides BCI’s we talk about possibilities for healing the brain through stem cell transplants

Today 15:50   

Cho

OK, that is something quite different indeed …                                    

Today 15:51

John

Or using brain organoids to replace pieces of the brain affected by a stroke or cancer removal

Today 15:51   

Cho

Now those are indeed very interesting to me! Send me the article and I’ll happily go through it

Today 15:52

John

Sending as we speak! 😉

Today 15:53

Nietzsche Human all too Human, 580

Cho and John are talking about the following article:
The Abyss

In this post the dialogue is realised by an interaction of virtual characters, for more information please check the page “Virtual characters

John

The last topic I wanted to discuss with you is brain damage and diseases

Today 15:41   

Cho

I suppose you also have the classics here … Gage, Tan, HM, Clive Wearing

Today 15:42

John

Not so fast! Yes, Phineas Gage we have, “Tan” … that’s Louis Leborgne , right?

Today 15:43

Cho

Right, and “HM” is Henry Molaison 😉                                                   

Today 15:43

John

Oh, of course, we have him! Everyone knows him now because of the movie “Memento”.

Today 15:44   

Cho

I liked that movie because it is surprisingly accurate 😊                    

Today 15:45

John

Can I quote you on that? 😊

Today 15:44   

Cho

Sure, most blockbusters deal with memory loss in totally implausible ways, so … 👍

Today 15:45

John

We actually have him in the article for multiple reasons.

Today 15:45   

Cho

Obviously: like Leborgne, he too suffered from epileptic seizures, and his memory loss was due to the operation to “cure” them

Today 15:46

John

Indeed! We go into detail about why splitting the brain in half sometimes works

Today 15:47   

Cho

Yeah, it isn’t really a “cure” though 😏                                                          

Today 15:47

John

That’s what we try to point out, but it is similar to brain cancer: better to cut it out

Today 15:48   

Cho

I see your point, the lesser evil, but it is frustrating                             

Today 15:48

John

What is? 

Today 15:49   

Cho

Not actually being able to heal it, only to treat it with such coarse interventions

Today 15:49

John

The next article actually is about the future and the brain

Today 15:50   

Cho

Meaning new medical technologies?                                                      

Today 15:51

John

Yes and no … 😉

Brainless Myths

Brainless Myths

Brainless Myths

What I have just said of the network, on its structure and, above all, on the fact that all the parts of the central nervous system make up a part of it, proves the anatomical and functional continuity between nerve cells.

John

There are some really silly myths about the brain 🤣 

Today 15:41   

Cho

I know, whenever I teach an intro class that’s what my first lecture is about 😄

Today 15:42

John

We’ve got some oldies in there, for context, like the Reticular Theory

Today 15:43

Cho

I must confess I don’t know that one … 🤨                                  

Today 15:43

John

Oh, this is from the 19th century, before we could clearly make out single neurons and synapses ..

Today 15:44   

John

people like Golgi thought it was one giant network without gaps

Today 15:44   

Cho

Wow, I did not know that …  😯                                                      

Today 15:45

John

We use some of the old misconceptions to show that people seriously believed stuff we now know is nonsense 

Today 15:44   

John

so that the readers might get that some of the things they seriously believe …

Today 15:44   

Cho

… may very well turn out to be nonsense as well. 😊                

Today 15:45

John

We do all the classics: left vs right, male vs female, the brain works like a computer, etc.

Today 15:45   

Cho

That last one is so very annoying! Lots of students think that. 😊    

Today 15:46

John

We actually don’t go into the whole “artificial neural network” thing, but just point out that the brain isn’t organized like the PC on your desk.

Today 15:47   

Cho

That’s helpful, but as long we keep talking about “intelligent” machines, the metaphor will keep working both ways.

Today 15:47

John

Maybe we could point out something like that in the article too …

Today 15:48   

Cho

I’d like to add a myth, if you don’t have it yet: mirror neurons  

Today 15:48

John

Aren’t they real? 😄

Today 15:49   

Cho

Sure, but they’ve been overhyped and people tried to use them to explain anything and everything

Today 15:49

John

I see. You’re right, I remember there were a lot of publication linking them to empathy, autism, learning any physical skill, etc.

Today 15:50   

Cho

That’s what I mean: hype. They exist and are interesting, but can’t explain everything.

Today 15:51

John

OK, good one, I’ll check with the other writers and likely add a paragraph about that. ☺️
