Brainhack Global 18 in Finland has just started with prof. Em Riitta Hari @aivoAALTO talking about the unsolved questions in neuroscience #bhg18 #bhg18fi
"how good are your data?" often theory comes before data (e.g. physics) and many labs do same experiment and results are combined #bhg18 #bhg18fi
"animal models, are we using the best species out of 8M species in the planet?" #bhg18 #bhg18fi
"Standard lab animal models were chosen because they were easy to breed" Yartsev science 2007
Paper here (2017) science.sciencemag.org/content/358/63…
(live streaming of #bhg18 #bhg18fi here )
RH "think about functional principles about brain function: evolution" #bhg18 #bhg18fi
"the brain has evolved in the real world" #bhg18 #bhg18fi
RH "During evolution we got multiple simplifying priors: circadian rhythms, gravity, etc" #bhg18 #bhg18fi
Because of our priors we are subject to (visual) illusions, mechanics are imprinted in our brains. #bhg18 #bhg18fi
"The brain is never isolated brain <-> environment <-> other's brains" #bhg18 #bhg18fi
"Connections in the brain are reciprocal between areas and levels and almost always bidirectional" #bhg18 #bhg18fi
RH "inhibition is essential" "amongst the greatest inventions in evolution" #bhg18 #bhg18fi
RH "we are good at aiming at something (motor action); selecting the proper motor action requires control" (as in feedback/feedforward I add)
(side note, check the stream @aivoAALTO 's toe writing skill is actually quite good!)
"Body and behaviour: only in fairytails the mind is independent from the body" (The Smiths: "does the body rule the mind or does the mind rule the body? I don't know") [that was my personal addition]
"mice posture was able to reconstruct movement" cell.com/neuron/abstrac… #bhg18 #bhg18fi
RH: "Complexity vs simplexity" people always say "the brain is the most complex devise in the world" "there are extremely complicated things, not just the brain" #bhg18 #bhg18fi
"To cope with environmental complexity, human and animal brains rely on simplifying principles that allow adaptive behaviour" Alain Berthoz Simplexity #bhg18 #bhg18fi
RH @aivoAALTO recommends the whole book #bhg18 #bhg18fi amazon.com/Simplexity-Sim…
And finally "Time! Timing is necessary" #bhg18 #bhg18fi "snapshots are not enough"
"Even in fMRI they are emphasizing the importance of time with Dynome cell.com/neuron/fulltex… and Chronnectome sciencedirect.com/science/articl…) #bhg18 #bhg18fi
RH take home messages:
1) functional principles
2) reciprocal connections
3) inhibition
4) body and behav
5) complexity and simplexity
6) timing

This is important. Yes, re-identification of de-identified brain MRIs is possible, but it is considered to be a crime under GDPR, implemented as “data protection” laws in EU (each country made their own laws and legal consequences).
Pseudo-anonymisation assumes that it is “highly unlikely” to re-identify the data. This means that for those cases in which it becomes trivial to reidentify a subject (eg rare case study subject), special care is needed and it should be the ethical committee with the researcher..
...to decide on benefit for science/society vs potential harm to the individual. Also: I believe that sensitive data can still be shared on a per request basis as done by human connectome project or ADNI, but legislators have still to finish their job as these relate...

😂 let’s close the internet, Michael @mfwells5 just won it!
For those who don’t know the reference:
Now I wish I didn’t have to go to sleep so I could remix the song with a robot voice that reads the 100 feelings 😂

"Suomen Akatemia | Academy of Finland followed you" 😲 ...
🤣
For the non-Finns to understand the joke, @SuomenAkatemia is a huge source of funds for research in Finland and basically every scientist is applying for a grant every September. Maybe this year will be my lucky one? 🤣😆😉

Good morning! The Last Jedi novelization comes out in PB Tuesday. I'll offer some thoughts from the writing process in roughly chronological order. Hopefully it will be of some interest/answer some of the Qs folks had. (For which thank you.) amzn.to/2zrkytY
OK, that prologue. It's *NOT* a vision of a better life for Luke. It's a warning from the Force, which has used a dream to slip through Luke's defenses. In both dream and reality, Luke's life is seemingly tranquil but evil is ascendant everywhere else in the galaxy.
Why start there? I wanted to open with Luke and step back in time; to be in Luke's head in a way that would be harder later, when we're exploring Rey's story and he's a mystery she's trying to solve; and to introduce the idea of the Force as almost a character in its own right.

0/ A plethora of #crypto- and #blockchain-related events happening within the past 24 hours!

Below, a thread I've put together to help you keep track of it all. May it serve you well.
1/ 🌉 @POANetwork [ $POA ] announced the ERC20-to-ERC20 TokenBridge!

Now, projects can leverage separate #Ethereum-based networks to communicate with one another through the transformation of #ERC20 tokens. #Blockchain interoperability growing strong! medium.com/poa-network/in…
2/ 🚢 The @EthexMarket team shipped its Ethex Trade Wallet, a unique native mobile #dApp that features hassle-free #ether and #ERC20 token trading. Compliments their existing #Ethex browser dApp nicely! medium.com/ethex-market/i…

Recently, a #tenured #prof at a grp dinner made a #sexist joke. I didn't laugh.

He pointed at me & called me out on it.

"See, I knew SHE wouldn't get it."

I reported it to an #administrator & copied a 1st yr prof also present at dinner. She corroborated my story.

Thread 1/7
Like me, she couldn't say anything during dinner as senior prof collaborated w/ our prog, which he reminded us several times. The administrator I spoke to was sympathetic & concerned, & assured us that senior prof is a well-known a**. We aren't the 1st to run afoul of him. 2/7
Hearing their responses validated my experience greatly.

The 3 of us discussed how junior prof & I would deal w/ future events. One way was to ask senior prof to clarify his "jokes."

Junior prof said this was likely to be the least destructive. Administrator agreed. 3/7

#b Excellence is overrated, competence is underrated.
Competence is knowing what to do in a situation and how to do it. It is not the same as excellence.
Excellence is dependent on other people, like judges, examiners, teachers, assessors, inspectors, auditors. But we can't control these people and whether they think we're excellent or not.

You have heard about our #AI Code and #global summit, but take a look at some of our other recommendations in the #LordsAIreport #justkeepreading: ow.ly/DnC930jyxZT
We had a lot to say about #data and #AI, and who should have access to it.
We also thought carefully about #diversity and #representation in #artificialintelligence and how we should address #bias and #prejudice

#b 'Teknik menjawab' is not a series of rituals that you carry out to secure an A in the exam. You don't get guaranteed an A just through superficial actions like highlighting keywords or drawing meniscus or inserting isi tersirat.
The problem is students and teachers treat teknik menjawab as some sort of pseudo magical ritualistic gestures that will bring a certain outcome. Draw a pentagram, slaughter a chicken, and your wish will be granted.
Some remote Pacific Islanders in 1940s came in contact with Allied and Japanese soldiers who were more technologically advanced and thought the soldiers were gods who had many "cargo" (canned food, electronics, modern stuff)
