To understand the ability to orient ourselves in space, UCL neuroscientist John O'Keefe studied the movements of rats and signals from nerve cells in the hippocampus, an area located in the centre of the brain. He found that cells in the brain formed a kind of internal map, an internal GPS. For this work he was awarded the Nobel Prize in Physiology or Medicine in 2014.

John O'Keefe received a PhD in physiological psychology at McGill University in Montreal, Canada in 1967, and then moved to England to do research at University College London. He stayed in London and in 1987 was appointed professor of cognitive neuroscience at University College. John is currently director of the Sainsbury Wellcome Centre for Neural Circuits and Behaviour at University College.
This talk was filmed at the Ri on 29 March 2019.

This guy won a Nobel Prize, Im gonna listen to what he has to say.
When I worked at a community college, I was once "accosted" by an older man who asked how to get to a certain classroom. I gave him what I thought were simple instructions as a right and a left turn to get to a different hallway to find the room. He was completely baffled. I took a different approach. I grabbed one of the building maps that were posted near every door. I showed him on the map where he was and where he was going, and used a yellow highlighter to highlight the route to the classroom. His face showed mild panic, and he said, "I don't know how to use this." It was then that I realized that this man had some sort of impairment to his ability to orient himself and navigate in space. I walked him to his classroom.
When my mom got a concussion it was really hard for her to orientate in space
@@jacobperry7637 I immediately thought of this incident while I was listening to Dr. O'Keef's fascinating presentation. It really explained what was going on with this man. I hope that your mother is doing better.
Good for you! It's mighty noble to help an elder. It would take many like you to help the average high school graduate. They could learn much from the elder, and much from you. Kudos.
This lecture is a-maze-ing ;)
if by amazin you mean boring then, yes, snugglepuff
Abraham Lincoln is a neuroscientist? Sweet!
If you look closely, he is car model.

Aha, Ok, I see he is the most expensive one too, the "Navigator"
It feels like you telepathically robbed my brain and beat me to it,
I was going to say - "he could be a descendent, because he has emulated A.L's facial hair styling."
Or,
I suppose he could have visited a barber shop that was selling "The Lincoln" for a special discounted price.
Ab's brain mapped the theater. :)
C. Everett Koop practically was; John O'Keefe might be their test-tube clone. 🤔
So awesome. Love the topic.
I knew this guy, he knew left from right but would call me in the middle of the night because he was lost as a pedestrian. First thing I had to tell him to do is to tell him to go to the nearest corner and look at a house number to see if he was North or south of the main east West avenue and East or West of main street North and south. Some times he would walk two or three miles the wrong direction before he called me and would be discouraged at the 2 or three extra miles he would have to back track. This only happened after dark. The sun was gone so he got lost. Could I get him to buy a compass and carry it? Nope. Half the day it was not needed. He couldn't figure out Google maps of course but he could remember my phone number.
I like the summary at the end
Fascinating and exciting about of have the Brain handle navigation and «where am I and where am I going»😊
You know this reminds me of how maps are made for tomahawk missiles. Except the missile has the map made from a 3d map referenced from a side looking multimode radar slaved to a ring laser gyro system. My dad was a cartographer in the Army Corp of Engineers while he was in WW2. He was stationed in Jenson. The town / base was named after the general that was the administrator. On his maps that he helped make the town was called Inchon. Yep, South Korea. MacArthur used some of his maps six years later.
Octagonal rooms mess me up quickly. I am also a ride share driver... I haven't been in octagional rooms since I started.

I felt the urge to applaud my monitor at the end of the video. Do I have some kind of spatial cognition impairment?
seems more like and affect inhibotion-thingy to me.
I often stiffen up if someone in a movie is falling ...
I know! It was a strange start, but I got hooked. Sad when it was over, I could have listened longer!
what kind of maps of meaning is this?
the navigation part of my brain throws errors all the time
Perhaps Kant is correct. Your DNA and biology play a part in how you perceive and react to the current conditions that surround you. It is okay to admit that.
Great video thanks. I've seen a couple of videos on how human's make maps. Having spent a couple of years in the northern hemisphere , vs 60 odd down south, I've always wondered why the human brain can't translate the hemispheres properly. I mean east is in the same position and north, south and west relative to light cues. However at home in the dark in unfamiliar places I almost always know where northish is, around 10 - 15 degress NE or NW of Nth. Go to the northern hemisphere and I have no clue , even after two years, unless I can see the sun. Regularly head east by going west.
I'd love to see what changes when I do that

Really interesting lecture, enjoyed it!
Also, i didn't expect to find so much stupidity in the comments...
29:15 is this loss
16,118 views right now and 56 comments. Only 56 comments!!! How can so many have so little to say?
Sadly, most of the comments are about the video game mentioned for like five minutes or who this guy looks like. A few more comments were jerks saying rude things about the presenter. I can't believe how pitiful the comments section is and why some people even bother. Would any of these jerks come up and say those things to his face after the lecture? Scared little keyboard warriors... Modern day children don't grow up, they just get older. Let's move on from the stupidity.
This was a great topic and an interesting presenter. I was sad when it was over as I could have listened longer. I could tell he was nervous. He obviously has great respect for the RI and the desk he stood behind. I fear great traditions like this will be lost in favor of some compilation of funny vines. Long live the RI and it's though provoking lectures!
I always wondered how the brain navigated the world. Sometimes we have directions but no mental map, other times we have a map but no directions. It's amazing what has be learned by this and other researchers on this topic. The cells the fire at specific locations or boundaries are amazing discoveries. The connections with disease detection early on hits home as my grandfather has Alzheimers.
They spent all that time removing stuff instead of asking the Duke nukem team for console commands? Lol
gamers unite
Mans looks like Abraham Lincoln haha
20:00
Thanks for this very interesting video. I saw, that they did not exclude all guns in the game: looking at the map, I saw a gun: the street not at a right angle is the handle of the gun. And the other streets followed the outlines of a gun or pistol. Do other people see this gun too?
Son of a gun!
The 1 guy who disliked this doesn't have a brain
Then there were 3, who couldn't get past the first 15mins.
I was wating for a talk about the construction of the world outlook and navigating reality... It's about mapping the territory, not the world =(
The active brain part has to be most primitive?
The modified game at 16:25 appears to be Duke Nukem 3D.
Indeed it looks like that ;)
Come get some!
Abraham Lincoln reincarnated
Dont forget the military way : "This direction, 700" (including pointing with an movement of the complete arm (eliminating errors) and ignoring obstacles between the standpoint and the target ( as obstacles are unforseeable and rely(trust) on the ability (which is unknown to the giver of the information) of the receiver to overcome it ) ) 🙂 just sayin. Doesnt relate to the neuro topic.
Thank you, Capn' Ahab !
Would have been cool if there are space-time cells as Einstein tells us the world is :)
I had to click this just to check if the guy was real. From the thumbnail he looked like an animated character.
With three spatial dimensions, the third dimension applies to the first two. If you have height and width then depth applies to both of them. The third unit (dimension) is the first two combined as per the numbers 1, 2, and 3 (3 being 1 plus 2). If we live in a fractoholographic reality running on quantum computations as a simulation, then the same fundamental trinary geometry is being used at all scales. Quantum computers use the 'zero' and the 'one' as well as the third unit which is the qubit (zero and one together undifferentiated). This would offer an explanation as to why Kant was correct about the brain knowing three dimensions before it intakes data. Reality could be a three-dimensional construct designed from trinary units. This would, of course, include the atom.
heinous?
No lie thought thumbnail was a wax figure
Abraham Lincoln
I wouldn't be so keen to get into any theater if I were him
I wouldn't be so keen as to be rude to someone who's worked so hard and for so long on a difficult topic. I'm sure he was dumbing it down enough for most knuckle draggers on TH-cam to comprehend. Notice most of the comment are about the video game or that he resembles Abe Lincoln... so sad. I watched it all the way and he did a good job. I learned a lot from him, not so much from your comment. Try and contribute a little bit more next time.
@@ToxicityAssured appropriately named "Toxicity Assured"
Who ever lectures in the RI and starts with...
It's a pleasure and honor to stand behind that desk...will always get my thumb up for a start.
All those who don't should find another job and flip burger.
Can you believe all the comments about what game it is or who he looks like! It's like people didn't even watch it for the actual topic. I also liked early because his respect for the RI and that theater is obvious. He was nervous, but did a great job. I was sad when it ended, I could have listened longer.
Lincoln reborn :)
He seems to be mixing up digital worlds/cgi with VR.
Tom Franco You seem to be confusing the concept of VR with the specific technology of VR headsets.
Abe?
Immediately thought this is proof of immortals!
I notice that the lecturer uses the metric system to measure walking distance instead of yards and feet. The British Roman measuring system is more intelligible for everyday use of Yards, Feet and Inches. Meters, Centimeters being British have no real understanding of measurement because a foot being 12 inches is similar to ones foot and a Yard as three feet is readily understood as ones step in walking.
Why go to all that bother to get rid of monsters in a FPS game? Just run it with the -nomonsters flag. Problem solved!
This nigha know he abein it up.
So Rudolf has a big red nose because nobody would play reindeer games with him!
Reincarnation could have some truth to it.
And what point in the video led you to that? Could you specify a time please? Could and couldn't are just two sides of the same coin. Reincarnation could make you fart a lot for the first few months in your new body or it could just be a lie.
I though Abraham Lincoln was dead
Trying way too hard to look like Abe Lincoln

Did you read the title before you clicked? Maybe a vines compilation is more your academic speed.
