Today I present the second installment of #NeuroThursday: why your brain uses twice as much energy as your heart!
I have begun a semi-regular Twitter feature: #NeuroThursday, where I discuss some cool neuroscience-related or -inspired topic for a public audience. The inaugural topic is Neolithic trephination!
(Yes, I know today is Friday. Shhh.)
Please let me know, here or elsewhere, if you have any topics you’d like me to think about. The more ideas/requests I get, the more often I’ll be able to do this. I want to go broadly here: if you have any topic you’d like to hear a neuroscientist’s take on (from brain to behavior to ???), let me know and I’ll consider it!
My nonfiction neuroscience essay, “The Evolved Brain,” is up in the January issue of Clarkesworld!
I’d like to use this space for a bit of bonus content: the eleven links and footnotes I’d originally included. We decided to remove them during the editorial process, but if you want to see the sources for my claims, here they are for posterity:
- Dr. Marcus’ quote about what “No overarching theory of neuroscience could predict” comes from this New York Times editorial.
- For more details on the Information Processing (IP) model, this wikipedia page is a good place to start.
- The quotation “All models are wrong, but some models are useful” is generally attributed to George Box, in this book’s original 1978 edition. The variant “models have no truth value” comes from this 2013 article on Bayesian statistics.
- For “our decisions remain riddled with biases and errors” (and “sloppy and unreliable kludges”), I like to cite this wikipedia article. If you printed out that list of cognitive biases, it would stretch for 10.5 pages.
- “Moral uncertainty induces movement uncertainty” is reviewed in this article. It’s a more general phenomenon about cognitive states influencing action, but the more difficult yes/no judgment questions include ones like “is murder ever justified?” (See the “High-Level Decision Making” section, starting on page 4.)1
- “Conscious memory is an unreliable reconstruction” is a widely-known phenomenon, but there’s a good academic review here, and good wikipedia examples here (including the “see also” links at the bottom).
- The presence of separate systems for vision-for-perception and vision-for-action is a discovery of wikipedia-level magnitude.
- The way optical illusions separate vision-for-perception from vision-for-action was first confirmed here…
- …and here is the specific example of the Ebbinghaus Illusion unaffected by vision-for-action. This is one of my all-time-favorite articles, because its main thrust is about the strange interaction between the two visual subsystems and handedness. But that’s a whole separate article.
- The role of the cerebellum in movement self-prediction has been understood since at least 1998.
- The Affordance Competition Hypothesis is best described in this 2010 review, but sadly not available for free anywhere online. The 2007 original article is available, but much less readable.
- If you want to watch those neurons following the ACH, those data originally come from this 2005 study, though you can find a lovely graphical summary in the article linked in #5, as well as the 2010 article in #11.
Finally, if you haven’t read the essay “The Brain is Not a Computer” (Aeon magazine, May 2016), I recommend it. I agree with its overall direction, and I think it makes a lot of good points, but it fails because it relies on a straw-man misunderstanding of the IP model, tied to the specifics of computer architecture. The internet is full of rebuttals, and largely fair ones. That’s why I wrote “The Evolved Brain” to show not why the IP model is wrong, but instead why it’s unhelpful, if your goal is to understand the human brain and experience.
2016 is drawing to a close, and in terms of my writing, it’s been an incomprehensibly good year. I’ve had the immense good fortune to sell and publish five short stories. I hope you’ll read some of them, and enjoy them; and if you consider anything I’ve done worthy of some kind of award nomination, I would be thrilled and flattered beyond belief.
I list my stories below in approximate order of pride, so if your time is limited, I strongly recommend #1. Insofar as I’m pushing one story as award-worthy, it’s “The First Confirmed Case of Non-Corporeal Recursion: Patient Anita R.“
Only a terrible parent would show such favoritism. But thankfully, we can show love for the whole family! I speak with the utmost of blustery impostor syndrome pride when I point out that this will be my first year of eligibility for the John W. Campbell Award for Best New Writer, and if you enjoy my body of work, I hope you’ll consider me.
Thank you for reading!
- The First Confirmed Case of Non-Corporeal Recursion: Patient Anita R. (Strange Horizons, June 2016; modern fantasy, 3400 words). A ghost story, with a classic recurrent haunting, but told from the ghost’s perspective. Also the ghost used to be a scientist. About how relationships survive or change across gulfs of habit, time, space, and death. Publication notes here, audio version here.
- Meltwater (Strange Horizons, March 2016; science fiction, 2200 words). Love among the posthuman. The less I spoil about it, the better. Publication notes here, audio version here.
- The Time Cookie Wars (Flash Fiction Online, August 2016; science fiction, 970 words). Time travel black comedy! About all those times you blame your past self for your mistakes, and also about delicious baked goods. Publication notes here.
- Sweeter than Lead (PodCastle, July 2016; dark fantasy, 2700 words). Neo-Lovecraftian: cosmic dread in the face of a hostile universe, without the underpinnings of racism and xenophobia. About addiction, succession, and malevolent prophecies. Publication notes here, audio version here.
Let me keep the coals hot here with a quick monthly update…
- More travel. Oh god the travel. But it was fun! I ate 5 thanksgiving dinners! And now I’m back.
- Novel revisions coming along, a little behind schedule, currently hope to be done by the year’s end.
- May be shifting up my convention plans for 2017. Jumping toward the Nebulas, which may mean skipping Capricon. Still aiming for Worldcon but don’t know enough about my summer schedule.
- I wrote and submitted a nonfiction article to a major market! They accepted the concept pitch, but we’ll see about the article itself. “The Evolved Brain” is based on the second half of the talk I gave to the Viable Paradise Reunion in October.
Help support an awesome new SFF magazine thrive and grow! In its first year, Metaphorosis has published a host of beautifully-written stories by awesome folks such as Karl Dandenell, Kelly Sandoval, Mari Ness,and over 40 others (myself included). Every story goes out onto the internet for free, but Kickstarter funds will let them do fun things like add podcast narration and pay higher rates for their authors.
And if you donate at the $75 level, you might get a story critique from me!
- Attended the Viable Paradise 20th reunion, and gave a neuroscience talk on how to understand the brain. For the countless among you who missed it, fear not: I’m working on adapting my talk into a nonfiction article for various publications!
- Finished up a new short story, “The Hammer’s Prayer.” It’s in the second-draft stage, will need some more thought & revision before it’ll be ready for launch.
- Sold my first reprint, of a short story that didn’t get spread far on its first sale!
- Continuing apace with second-draft revisions of the novel. May not hit my December 1 self-imposed deadline, but I won’t be too far behind it.
- Thus, instead of doing NaNoWriMo, I’m doing NaNoFiReMo. (That’s “Finish Revising.” Or “fire,” as needed.) But no promises since I have multiple end-of-November deadlines.
- Current short story status: 11 submissions circulating, 3 of them shortlisted.
I’m pleased to announce that my first published short story, “The Wind and the Spark,” will appear as a reprint in Digital Science Fiction! This is one of my older stories, but I’m thrilled to re-release it: it’s currently only available in a paid issue of a magazine that went defunct before it published me, so not a lot of people have read it. Stay tuned for a publication date.
September was busy! September continues to be busy! (What do you mean it’s not September anymore?) Monthly update all quicky-like:
- My short story Shiplight came out at Metaphorosis!
- The text version of Sweeter than Lead (previously audio-only) went up on Podcastle!
- First draft of new short story! So far, pretty terrible!
- Novel revision status: behind schedule, but progressing! I’ve solved all the big structural problems, now I just need to implement it all.
- I attended a Social & Conceptual Issues in Astrobiology conference. Super-amazing!
- Spent today at Archon! Had my first public reading, and I was on a bunch of fun panels. Got to play the expert for a little while, and meet a bunch of excellent people.
October will include 3 weeks of travel (2 for work, 1 to visit family). Hopefully I can get a lot of revisions done meanwhile!
I spent last weekend at the Social & Cultural Issues in Astrobiology 2016 conference at Clemson University, South Carolina. A small academic conference (~30 people) discussing nonscientific issues surrounding astrobiology and space exploration, and an absolutely amazing chance to spend two days thinking through the future among some of the world’s foremost thinkers and researchers on the topic.
If you poke around the website, you can find abstracts on all 26 talks: two one-hour keynotes and 24 half-hour talks on everything from ethics to gene theory. Starting on the 3rd talk1, I livetweeted my notes and comments. For an overview of some of the top concerns and opinions around space travel, take a look through the Storifies below!
