How Scientists Found a New Neuron Hiding in Our Brains

Good news. We all have a new brain cell. And it’s looking like this particular kind
of brain cell could be unique to humans!. Do you feel smarter yet? Well you’re about to, ‘cause we’re gonna
talk about your brain. Which, it turns out, science actually knows
very little about. We’re JUST starting to scratch the surface,
and mapping the brain is a far greater challenge even than mapping the human genome. But let’s go over some basics:
Your brain is full of cells: neurons, and glia. We’re going to focus mostly on neurons,
which are the messengers of information. Neurons communicate with each other and with
the rest of your nervous system through electrical and chemical signals, and are supported by
glial cells. There are three main kinds of neurons: sensory
neurons, which communicate information from your senses to your brain; motor neurons,
which help you control your body’s movements, and interneurons, which help motor neurons
and sensory neurons talk to each other. Within these categories, neurons can be either
excitatory or inhibitory. As their names suggest, excitatory neurons
pass information along to other neurons, while inhibitory neurons can slow down excitatory
action and stop other neurons from firing, controlling the flow of information in the
brain. And the big news is that we’ve found a new
kind of interneuron, called the rosehip cell–sittin’ right there in this vast, unknown universe
that lives inside our own heads. What’s particularly exciting about this
new research is that scientists are starting to use novel methods to delve into the brain. Recent advances in RNA analysis techniques
called transcriptomics allow to see more detail than ever before about how the brain works. A group at the Allen Institute for Brain Science
in Seattle used these RNA sequencing techniques to identify unique gene expression patterns
in frozen brain tissue. Meanwhile, a partner research team in Hungary
used more traditional slice and dice lab imaging techniques–on live brain tissue taken from
brain surgery patients–to see evidence of a cell that matched the genetic markers found
by the Seattle group. Ta da–brand new brain cell type, observed. So how does it affect human behavior? We’re not quite sure. Yet. The rosehip neuron appears to act as an inhibitory
neuron. It’s called the rosehip neuron because it
looks like the plant, and its specialized shape, with rosehip-like bulges on its axons
may help it act on the brain in a particular way. Lots more research is needed to discover the
effect of rosehip neurons on human behavior and cognition, but there are early hopes that,
as a neuron that controls information flow in the brain, it could be a key part of understanding
intellectual disability and neuropsychiatric diseases like schizophrenia. Perhaps the most important part of this discovery
though is that so far, we haven’t been able to find the same kind of brain cell in the
mouse brain. We rely on mice to study everything from cancer
to pharmaceutical development to alzheimer’s, so this lack of an analogous structure in
the rodent brain highlights how different the two really are. This discovery in particular points out important
gaps that may result from trying to study human brain function in mouse models. We’re making valuable progress in the vast
unknown frontier of our brains, but there’s still a heck-of-a long way to go. Does your brain hurt from all the knowledge? Subscribe to Seeker so we can guide you through
all the brain learnin’. And fun fact, there’s a project in the US
called the BRAIN Initiative, which stands for Brain Research through Advancing Innovative
Neurotechnologies, and is dedicated to improving our understanding of the human brain. Thanks for watching.

  1. I have the number of the internet, I'll call the internet to verify this information before I believe you. I'll believe the internet first.

  2. Lol and biologist always say we arent special. I knew my consciousness was right, I always had an unexplainable feeling that I am not the same as every other animal. As if every other species is in a box, yet the human is outside the box looking in

  3. in time the brain computer interface will restore our health without us knowing it or without our consent. if our body is deficient in red blood cell serum, the host computer will govern our brain to activate liver function to increase or decrease blood cells according to their portion. And the human immune system will be controlled by the host computer. Cell regeneration will also continue to replace every damaged cell, even though the environment is contaminated with toxins.

  4. Pardon me, I seem to have misplaced a few vital neurons due to mom's choice of substituting breast feedings, with MilkDuds and her trusty slingshot from across the room, and sometimes she missed the mark. So, am going to require the use of loaners please, to run off some copies with that machine over there, seeing as how nobody has created the Dyslexia++ programming environment of which to further develop with. 💻

  5. So basically the people who graduated this year with a neurobiology degree are all undertrained in their field 😂

  6. Bachelor's of Science, Biology and Environmental Science & then from then on it's just Science Communication. You wouldn't call Biology a hard science exactly nor does Science Communication gives you the hard science in other branches of science.

    I get it, it's becoming more cringe-y to be associated to a certain somebody, specially one being attacked personally & worst,  professionally, by pompous academics, who themselves secretly wish they could distinguish themselves, at the very least.

  7. If it’s unique to humans then that means chimps and other primates don’t have it, and that’s a pretty significant difference between us and some of our closest relatives.

  8. 2:39 "So this lack of an analogous structure in the rodent brain highlights how different the two really are"!
    Really? OMG, I was totally like, Mice and Humans are totally the same and God created Mice for Humans to test medicines on…like, totally! smh…

  9. Wonderfully informative and useful….but if I may:…..your opening statement that humans still know very little about the brain and its geography?…..totally misleading and false; since nearly the 60's we have had MOST of the information about what parts of the human brain do what and how such descriptions sufficiently explain the human self-conscious experience any species-centric toad hasn't yet risen above…….so, while, yes, there are still gaps in our understanding of the human brain and the resulting phenomenom of self-awareness and living are incomplete… erroniously and dangerously help forward a false narrative that we know little about the human brain and how well neurobiology is already able to (and has been for some time) explain the perceived complexity of human experience.

    Good intentions, interesting info……TERRIBLE intro to the suject, perpetuating decades of misinformation :/

  10. It's not a new neuron… it's a newly discovered neuron. Meaning we don't know everything we need to about the brain. Soooo when a doctor gives you medications for an unknown whatever is going on in your brain, I wouldn't take it.

  11. Reading our DNA was easy, understanding it, generally impossible. Mapping all our neurons, complicated, and potentially of limited value as it's complexity may be beyond our ability to fathom without understanding the "math" in the DNA that created it in the first place. Its like an alien trying to understand an enormous human city my mapping all of its roads. Lets face it, we don't understand how a neuron works. Such a long way to go…

  12. We can't even make proper discoveries about ourselves and environment, yet we are so proud of ourselves and deny the existence of Almighty. Our pride will be threat to our race.

  13. There's a high pitch sound every 4 seconds in the video after 1 minute in. Don't know if it was on purpose so just letting you know in case it isn't.

  14. So, lets get classic then. Sentenced to death prisoners as test subjects. Or lets get scifi: human clones as test subjects.

  15. Why would you say it's new in the beginning, when in reality we've all have already had this neuron for all of our lives

  16. Why is there a hard to hear beeping, like a slow and quiet smoke alarm in this video?
    Starts at 1:02 and seems to be part of the music. Without headphones it sounds more like a beeping.

  17. Man may be divine in essence, but man is still animal in substance.
    New findings prove that the human brain has regenerative capacity.
    So good to know this.

  18. You can’t say that it is a new neuron cause it probably has been there since the evolution of mankind. Only now that they hand discovered an undiscovered neuron that’s why they called it “new”

  19. Well well mighty mouse done it again this he got a new braincel rosehip makes for a good comic plot there are still many unanswered questions but for mine thank you so much

  20. It has the similar geometry to a tree, a fractured crystal or the dark matter scaffold that contain galactic superclusters. The fractal is a clearly visible analog to the legendary stickman of aboriginal lore.

  21. years ago…while i was partially sleeping…not a deep sleep…..not dreaming any thing…I had an explosion inside my head or brain which lasted maybe 3 to 5 seconds…i dont what it means??? but i notice some difference…before i dream fantasy…now its all reality…and i remember my dreams…also other changes….i have a high tolerance for pain….etc….

  22. Wear you glasses and i will subscribe to seeker. Every morning, putting plastic in your eyes, so you can look like a 'normal' person, is stupid.

  23. It looks like it could be the northernmost spinal ganglion. It's probably some kind of an extension of the spine in the brain, with a similar function.

  24. whose brain was that fucking find out it first and then say every people have same extra new shit like u have found

    Why a “genius” scientist thinks our consciousness originates at the quantum level.
    A 2013 study by Japanese scientists added some proof to the theory by Penrose and Hameroff as researchers detected vibrations in the microtubules. Penrose and Hameroff then proposed that by focusing brain stimulation on these vibrations one could conceivably “benefit a host of mental, neurological, and cognitive conditions.” The Big WOW
    Penrose and Hameroff have developed a theory of consciousness called ORCH OR (Orchestrated Objective Reduction of Quantum Coherence in Brain Microtubules) which posits that consciousness "occurs" not at the neuronal level in the brain, and not in algorithmic processes mimicking on a grand scale the way computers work, but at the sub-neuronal level, in the microtubles (crystal-like lattice structures that help organize cell structures and enable information processing) in which quantum processing interacts with classical physics.
    Orch OR (“Orchestrated Objective Reduction”) is a theory of consciousness put forth in the mid-1990s by British physicist Sir Roger Penrose and American anesthesiologist Stuart Hameroff. Whereas most theories assume consciousness emerges from complex computation at the level of synapses among brain neurons, Orch OR involves a specific form of quantum computation which underlies these neuronal synaptic activities. The proposed quantum computations occur in structures inside the brain’s neurons called microtubules.

  26. Maren is a truly beautiful woman. She could be reading the dry text of an End User License Agreement and it would still be mesmerizing. To me, she is like the perfect wife and mother. Pretty, smart, lively, and an effective communicator. I mean, just imagine her has the mother of your children. The awesome beauty of nature manifested in human form. * Sigh *
