I ask periodically but haven't found an answer yet. My partner has dyslexia, and I definitely don't have that (I can easily help her spell any word she asks), but I when typing I transpose S/2/5, 1/L and of course 0/O. I also substitute words like suitcase/briefcase. I also reverse the order of letters. When reading, numbers in particular, the digits seem to shift around, and if a digit is repeated I struggle to count how many times it is repeated. Is there a name for this? #actuallyAutistic #dyslexia #brain #neuroscience

When I read research papers that are the result of very expensive work (experiments or simulations) I always want to know: how could this project have possibly ended with a null result? And is there an argument in this paper that compares the actual result to this null? If not, I'm very suspicious.

Actually this is a good question to ask about any paper, but the high stakes of super expensive research make it particularly important to ask the question. In my experience, it is surprisingly rarely answered in the paper and I find it hard to believe in these results.

When I transitioned from cognitive to computational neuroscience, I found myself in a bit of a bind. I had learned calculus, but I had progressed little beyond pattern recognition: I knew which rules to apply to find solutions to which equations, but the equations themselves lacked any sort of real meaning for me.

So I struggled with understanding how formulas could be implemented in code and why the code I was reading could be described by those formulas. Resources explaining math “for neuroscientists” were unfortunately quite useless for me, because they usually presented the necessary equations for describing various neural systems, assuming the presence of that basic understanding/intuition I lacked.

Of course, I figured things out eventually (otherwise I wouldn’t be writing about it), but I’m 85% sure I’m not the only one who’s ever struggled with this, and so I wrote the tutorial I wish I could’ve had. If you’re in a similar position, I hope you’ll find it useful. And if not, maybe it helps you get a glimpse into the struggles of the non-math people in your life. Either way, it has cats.

A very senior faculty member once told me that "back in the day" (when they were young) an interesting research finding would first get published as a brief note in Nature, and then a year later the lengthy, detailed manuscript with all the data and methods would appear in the Journal of Neurophysiology. And that one wasn't considered a serious scientist if the latter wasn't published, for the former was but the news splash with barely enough substance to understand what the claim was.

Tragic that this separation of concerns has been lost, with everyone now giving more weight to the flashy bit ("significance of findings"), to the point of not bothering to publish the lengthy, detailed, reproducible study ("strength of evidence").

These two axes are what eLife's assessment aims at capturing in a pithy paragraph.

#Zoomposium with Prof. Dr. #Dieter #Birnbacher "The #human #image of #neuroscience"

However, the focus of the interview will not only be on ethical questions concerning the current findings of #cognitive neuroscience, but we will also go into the possibilities of a "modern #neurophilosophy" or an "inductive #metaphysics" in the sense of #Schopenhauer.

We were pleased to welcome teachers and careers leaders yesterday to SWC, together with the Central London Careers Hub.

After touring our facilities, meeting staff and students to discuss diverse #neuroscience careers, they took part in an ‘escape room’ activity workshop.

It began with a rabbit: Unraveling the mystery of memory. 🐇

From @KnowableMag: "Half a century after the discovery of long-term potentiation, we’re still learning how the brain remembers."

Why nothing matters

It took centuries for people to embrace the zero. Now it’s helping neuroscientists understand how the brain perceives absences

50 years ago, Tim Bliss and Terje Lømo worked in the Oslo lab of the late neuroscientist Per Andersen, where they made a momentous discovery: the fact that when a neuron signals to another neuron frequently enough, the second one will later respond more strongly to new signals for hours afterwards. The phenomenon is called long-term potentiation (LTP) and it’s fundamental to how we learn and remember. @KnowableMag talked to Bliss and Lømo about their discovery, and to other neuroscientists about how they’re applying knowledge about LTP to their research about memory disorders, chronic pain and more.

Take home, or to school, message. Feeling safe, I.e., not threatened, is the best physiological \ environmental condition or environment, to learn in.

Chasing Consciousness: Dr. Stephen Porges PHD - POLYVAGAL THEORY EXPLAINED

Spotify for CreatorsDr. Stephen Porges PHD - POLYVAGAL THEORY EXPLAINED by Chasing ConsciousnessWhat's the importance of safety to health?  In this episode we’re going to be talking about the neuroscience of safety and how our sense of safety can be hugely important to the way we communicate and learn. Research shows that when we perceive threat, we go into a hyper-vigilant state and certain circuits of the brain shut down to focus on self-protection. If we can become aware of this as it’s happening we can not only use certain tools to mediate it, but we can also help others not end up in that state too. We are extremely lucky today to go straight to the horses mouth so to speak of this research, speaking with the founder of Polyvagal Theory himself, Dr Stephen Porges. Dr. Porges is the founding director of the Traumatic Stress Research Consortium at Indiana University. He is Professor of Psychiatry at the University of North Carolina, and Professor Emeritus at both the University of Illinois at Chicago and the University of Maryland. He has published more than 300 peer-reviewed papers across several disciplines including, biomedical engineering, neurology, neuroscience, obstetrics, pediatrics, psychiatry, psychology, and substance abuse. In this episode we’ll be unpacking his Polyvagal Theory, a theory that links the evolution of the mammalian autonomic nervous system to social behaviour. The theory is leading to innovative treatments based on insights into the mechanisms operating in several behavioural, psychiatric, and physical disorders. He is the author of several books which we’ll be mentioning in the interview and you can find links to in the show notes. What we discuss in this episode? 06:29 What’s going on inside people’s heads? 09:00 If your body is in a state of threat you can’t access certain areas of your brain 12:49 What does the Vagal nerve do? 17:00 Facial expression and tone of voice broadcast our physiological state via the Vagal nerve 22:30 Co-regulation between parent and child 24:00 Polyvagal Theory explained by its founder 28:00 Bidirectionality: feedback between physiological state and mental state 32:00 Trauma, making ourselves numb, disassociation and turning off your body 35:00 Co-regulation VS co-exacerbation between individual and collective systems 40:30 Dan Siegal’s ‘window of tolerance’ 43:00 Error in thinking about trauma, of focusing on event and not on bodily reaction and feelings 45:30 Stephen’s new book ‘Polyvagal safety: attachment, communication, self-regulation’ 48:00 Physical and mental illness are the same, but medical professionals aren’t taught this 51:45 Vagal metrics to help explain ‘medically unexplained symptoms’ 57:00 Moving beyond Paul McLean’s outdated concepts of the Triune brain and the Limbic system 54:00 ‘Neural exercise’ (play and social interaction) should be a fundamental part of a healthy education 1:04:34 Being listened to is crucial to feeling safe 1:07:30 Voice cues for safety have been critical to man’s survival 1:07:40 The ‘Safe and Sound’ protocol for inducing clam and safety 1:12:00 Tools from Polyvagal theory for bypassing trauma triggers 1:13:45 Listen to your body don’t hack it.

ScienceDailyPossible foundations of human intelligence observed for the first timeA study has demonstrated how neurons in the human brain generate memories and establish narratives. Contrary to previous beliefs, individual neurons represent the concepts we learn, regardless of the context in which we encounter them. This allows humans, unlike other animals, to establish higher and more abstract relationships, which lays the foundation of human intelligence.

🧠 Melbourne start-up launches 'biological computer' made of human brain cells
—ABC News

｢ The neurons can be "taught" via small amounts of random or patterned information provided by the chip. The incorrect response receives random information, while the correct one receives patterned data. Eventually, the neurons start to learn what the correct response is ｣
