20 More Amazing Facts About Your Brain
The human brain is amazing and the more I read about it the more fascinated I become with not only it’s limitations, but also it’s immense power.
Since I originally wrote the post 30 Amazing Facts About Your Brain I have been on the look out for more amazing tidbits.
Here are another 20 for you to wrap your head round, but don’t make the mistake of thinking they don’t apply to you, because they do.
1. Your neocortex (the weird looking bit on the outside of your brain) is only about as thick as a dinner napkin and is made up of 6 layers.
However, if you were to pull yours out and stretch out all the folds it would be over 3 feet square. Unfortunately your planning skills would diminish rapidly and your ability to put it back in properly would be less than assembling a chest of drawers from Ikea.

2. Very strangely you are about 4 times more likely to marry somebody with the same last name as yourself than someone who has a different name.
Your brain just loves continuity and it loves familiarity, so even though you may consciously think your partners name had zero to do with you falling in love and it was really their perfectly formed personality, you’d be wrong.
3. If you were to get up off the couch and sprint hard for 20 seconds or so you would increase the workload on your muscles by about 100x.
However, if you sat down with Gary Kasparov after recklessly challenging him to a chess match after one too many beers, no matter how hard you concentrated you’d only require your brain to increase its workload by about 1% before being humiliated with fools mate.
Mmmm, Chocolate Cake
4. You’re 40 – 60% more likely to buy food you can reach out and touch than food somebody describes to you or places behind a glass counter.
That’s why the old fashioned sweet trolleys really do generate more sales and top restaurants know this.
5. Your sensory system sends about 11 million bits of information to your unconscious brain per second. However, the conscious part of your brain is not aware of more than 16 to 50 of those bits and the lightweight can only deal adequately with about 4.
6. You’re completely unaware of about 95% of the activity that is going on inside your brain. If you weren’t your brain would freeze up quicker than a Windows PC running ME
7. You’re far more likely to give a large tip to a waiter or waitress if it’s a sunny day because the chemicals released by your brain because of the sunshine make you feel happier and more generous.
And The Winner is…….Roland The Rat
8. The reason why rats can sometimes beat humans in certain laboratory tests is because they have no prefrontal cortex to plan with.
Therefore, they listen exclusively to their unconscious mind and the associated electrical responses or gut feelings, whereas humans can get all wrapped up in trying to plan their best way out of the maze and end up cheeseless and very, very embarrassed.
9. There are over 100,000 miles of blood vessels in your brain.
If you pulled all yours out you could stretch them round the earth over 4 times. Unfortunately, you’d die and wouldn’t be around to see your amazing feat, but you probably would make the Darwin Awards and that’s no mean achievement.

10. If you exercise your brain with puzzles, memory games and reading self development blogs (especially this one) etc you can continue to grow new neurons all your life.
Unfortunately most people don’t know this and thus presume aging equals cognitive decline and create a self fulfilling prophesy.
11. Your brain doesn’t want you trying to fly when you’re asleep shortly after you went to see Spiderman at the movies, so in effect it paralyses your body with a hormone designed to keep you from living out your dreams and dying a splattery death.
12. A piece of brain tissue the size of a grain of sand contains approximately 100,000 neurons and 1 billion synapses.
Your Brain Doesn’t Like Junk Food
13. What you eat effects the efficiency of your brain. A study of New York students showed that those who ate food filled with additives and artificial flavors were out performed by about 14% by those who ate more healthily.
14. Whereas 30% of your brain is given up to vision and all that goes with that such as spatial awareness, depth perception and recognition etc, your sense of smell is still the easiest way to create conditioned responses or anchors.
Smells enter the brain completely unfiltered by your belief system unlike other senses which is why smelling salts work so effectively.
The reason blind people often have other enhanced senses is because their brain thinks “Huh. I guess we’re not using that 30% for vision after all, we may as well use it for something else” and thus builds new neural pathways for the other senses.
Cerebellum Killjoy
15. The reason you can’t tickle yourself is because your cerebellum knows it’s you doing the tickling and send a message to the rest of your brain to ignore the sensation and refuses to laugh, the miserable bastard.
16. Don’t be too hard on the cerebellum though because it controls your balance and without it you’d make a drunken 3 legged donkey look like an Olympic gymnast.
17. If you get really angry your limbic system has taken over your critical thinking and it can actually become literally impossible to access higher reasoning.
Which is why some people can go postal and nothing anybody can say can calm them down.
Fortunately, if you remove the source of their anger the Limbic system returns to normal after about 20 minutes. So don’t count to 10 when you’re mad, count to 1,200!
What The F?
18. Unless you have done this test before you’ll probably fail miserably at counting the F’s in the following sentence:
FINISHED FILES ARE THE RESULT OF YEARS OF SCIENTIFIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS.*
19. Your brain is so soft that you could probably spread it on toast if you were completely insane and liked eating human brains and dying all at the same time.
20. It’s possible to be blind at a conscious level, but your brain is still able to see at an unconscious level. This is a phenomenon called Blindsight and has stopped many a blind person avoiding an open man hole cover much to their amazement (presuming somebody told them that is!)
20a. Your brain loves to connect to others and share information, therefore if you tweet or share this post on Facebook not only will I love you, but your brain will too. Win/Win!


Tim, you pointed out some very interesting facts about the brain… I also read your previous 30 facts. ;)
I’d like to say that I did not encountered a problem with counting the Fs in that sentence. Maybe that rule you mentioned applies only to native English speakers?
Yeh that could indeed be true. Either that or you’re a genius ;-)
I’m just reading through all these comments …. what a fantastic place it would be to get all these rather daft and very interesting people into 1 room to see a presentation of this ebook! Barking and all! Would put many a dog show to shame :-) … waiting in anticipation over the next 6 weeks.
I’ve already started Leigh and my goal is to get it finished before I move into temporary accommodation on 28th September.
Hi Tim,
Now known as Brianiac!
What have you now let yourself in for :O)
I for one would love to see this new ebookO you have ticking away in your brain… but I do hope the world is ready for it.
At my age where do I park all this new information?¿?¿… ah… under miscellaneous… where else.
Go for it Tim…
Looking forward to a good read.
Regards
Vic

I’ve already started Victor!
I’ve met a lot of Barking people lately..
You know the wife’s and my family then?
Another one I forgot to add earlier… A study done just a year or two ago shows that reading retention/comprehension (tested with several groups given the same material in different fonts) is higher when a font that is still readable but is not the usual Arial, TNR, Courier type of font is used for the printed notes or reading material. It is easier for us to skim something printed in the fonts we see most often. A new font requires our brains a little extra work to do the pattern matching, and it seems (along the way) that causes better retention of what we’re reading. Making the font too busy/complicated to read means a drop in retention.
Now that makes sense. Also we are more likely to pay higher prices in restaurants if the font is fancy.
We’re just plain weird.
Not quite so, Dave. Studies have shown several things about language studies. We CAN learn to speak a language at any age, but it is more difficult to reproduce the sounds not used in our own language after a certain age…I want to say it was somewhere around 12 or so. Babies are born making every sound imaginable…every sound that might be used in language, but they STOP reproducing the ones they don’t hear on a regular basis. It is theorized that they stop, because they focus on sounds they believe will get them an interactive response. Some language specialists suggest playing music from around the world and/or learning tapes made to engage babies in other languages to keep the sounds fresh in their minds for a longer period of time, with the aim of making relearning them in language lessons easier later.
Agreed and thanks for explaining so well Brenna.
Just found your stuff Tim. Fascinating. Can’t leave comments on the ’30 Amazing Facts’ one now so I’ll leave one here about no 28, I thought that not needing to pronounce the sounds of our language in their language was a factor, but as the brain is constantly developing and we have the ability to learn anything at any age.. We are all lazy as a race, (human race, not just Chinese) I still put it down to that. I wasn’t born a King Charles Spaniel but if I worked at it I’m sure I could master it’s bark.
No you couldn’t Dave!
Brenna answered better than I could below.
Always enjoy reading your posts. Would love to read the ebook! Just been behind, as usual. Thanks for all your hard work.
The book is coming Paula, give me about 4 – 6 weeks.
I still understood it, Tim. Doesn’t matter how difficult you make the words, it seems.
Yeh but you couldn’t read it anything like as quickly.
That was easy to read. Doesn’t hurt my head at all.
Brenna
Good, head hurting is never desirable.

Is this true? Wow, I’m never doing that again, it was murder on this little brain of mine!
Anyway, love your stuff and can’t wait for the ebook!

PS. Excuse my weirdness. “Men are from Mras” you know!
Wow, that was tough to read! I think there was something else involved in that exercise other than just the first and last letters but I forget what now.

Yes Please Tim on the ebook
David
Ok, give me about 4 – 6 weeks and it will be done.
Tim you are the man! Love this post and feel an expansion is a must! Bring it on brother!
I will do indeed mate!
Just as good as the first set of amazing facts. Having considered it, yes, an ebook would be very cool!
You’ve got it I’m definitely going to do it now!
Hey Tim. Nice list. The blood vessels one particularly surprised me.
I’m doing a 5/2 fasting diet. Apparently when you fast, it also prompts new neurons to grow in the brain. Cool, huh!
More info in this documentary: http://www.bbc.co.uk/programmes/b01lxyzc
That’s awesome, I have NEVER heard that before! And thanks for the link I’ll check that out too.
This is going to be fun!
The reason we need editors (and even editors cannot find all our mistakes) is that the human brain has the uncanny ability to complete and correct broken patterns from visual representations of them. For many years scientists focused on this with shapes (unfinished lines or dots that form a picture), but it applies to words as well. If you’ve ever taken one of the tests where the letters are scrambled or replaced with symbols and numbers, you understand it does work for many people.
This means you can see an error, but your mind may correct it before you consciously note it, in essence tricking your mind into thinking your eye saw the correct words in place, worse when the incorrect word is a sight word (not unlike the ‘of’ in your example replaced with ‘if’). The more familiar you are with what SHOULD be there, the more likely you are to make the correction and think it correct. An editor coming in fresh to the work is more likely to see the error, but there’s still a possibility he or she will not, for the same reason you didn’t. Hence the saying that no book goes out perfect.
A good way to counteract this is to switch to an auditory edit of the work. I don’t mean reading it aloud yourself. You’re just as likely to correct it and read it aloud as it should be. So is someone else reading it aloud. Instead, have a text-to-speech program read to you. You are more likely to hear the errors, especially if you are reading along with the written word at the same time.
Well that at least makes me feel better that it wasn’t my fault my first book went out with 30 mistakes in it, it was my brains ;-)
I do find how the brain works fascinating in understanding behaviour, and facts like these make it really accessible. So yes, an eBook would be fantastic. You provide so much great food for thought Tim.
Ok, I have enough people interested now so I shall do it mate!
Love reading your articles. thanks so much.
You’re very welcome Izabell.
Yes, this helps a lot and feel worth expanding.
Thanks Pramod.
By all means, do please make an ebook with 50-75 of these brain things – please include some items on optical illusions and frequency entrainment?
Thanks!
I have no idea what the latter is to be honest, but I’ll go and check in a moment, thanks!
Yes please to an expanded list of interesting facts!
Ok Helen you got it, thanks for asking.
Thanks Tim,
Interesting facts regarding the brain. Very useful when coacing clients as you can then set up structures ans strategies that take unconditioned responses into account.
A tip about changng habits: You need to have in place a short term reward if you are going after a long term target or goal. This could be an affirmative pat on the back from a friend, could be a coffee, small treat. Once the new habit is in place the reward isn’t necesssary and the act of moving forward on your goal or vision is reward enough.
Cheers
Yep, I always insist clients have sub-goals that are rewards in and off themselves to mark their progress and keep them motivated.
Hello Tim, I’ve been following your blog/newsletters for a while now. I like your no-nonsense up to the point style. It would be awesome if you could put together an eBook on all this stuff.
Cheers,
Jit
Your word is my command ;-)
Yes, Great stuff Tim
I appreciate the effort you put into your posts. It’s often posts like this when you ‘nominate’ x amount of interesting pointers on a particular subject, that grab the most attention. An e- book format would be most appreciated by me and I’m sure by many more.
Keep up the great work
be good to yourself
David
Thanks David and I’m going to do it I think.
Point #4: That is so true. Just go to the produce section of any grocery store. Moreover, it is my opinion that this goes beyond food. I get skeptical about buying clothes online or from a catalog. I want to touch the material.
As for your Ebook — I would definitely read it. I’m enjoying your one on being super confident.
Yeh my wife is like that as I suspect most people are. CD’s and books are great, anything tactile, not so much.
Ebook compiling amazing brain facts, yes.
One more vote, thanks!
Dear Tim:
Of course it would be very usefull if you send the ebook adding material.
For me, the article about the self destructing habits is fantastic. Specialy the part of the NLP Anchors, very, very interesting.
Sincerely I don’t need to be more confident, indeed, maybe my excess of confidence is part of my problem.
Sorry for my poor english, is not my main languaje.
Thanks and great job you are doing here.
Best Regards.
Juan, never apologize for your bad English I’m not even fluent in my own language never mind anybody elses.
Hey Tim,
Yes I think this is worth expanding. I’ve been watching some video’s on TED around similar types of topics and there were 1000’s in the audience and everyone was very engaged so I think if you keep your witty tone combined with pretty interesting brain kinda stuff I think you’re on to a winner.
Cheers
Leigh
TED talks are awesome, not sure I can match that level, but I’ll give it my best shot ;-)
If anybody would like me to expand on this post and make a 50 Amazing Facts about Your Brain and turn it into a free ebook, please let me know in the comments!
Tim,
I freakin’ love these posts. And hate putting together Ikea furniture with a passion. :)
Me too on both of those!
Some of these really caught me off guard, nice list. By the way I loved your geeky reference to Windows ME, made me really laugh. :)
I think this post and the previous one with some expansion could make a cool ebook. What do you reckon?
If you were to get up off the couch and sprint hard for 20 seconds or so you would… probably knock yourself out running into your living room wall :)
That’s an interesting point Chris, I need to edit and clarify ;-)
