Where is it marked that it is with an 3D printer?

I think it's the video that's rigged.
The index finger in front of the mirror is much too high and curved compared to that in the mirror.
The two thumbs should not be visible as shown in the mirror (observe the nails, the thumb of the left hand is clearly too low to be still visible in the mirror).

There are plenty of other places, notably at 0 "33s the object cannot be reflected by the mirror, because it is too" out of view "to be reflected.
Just as the shadows in the mirror are located the opposite of where they should be ....

But if you don't look at these details you don't notice anything, it's very well done. Morphing no doubt?

It's not April 1st !! This news is quite impressive! From the team: http://bluebrain.epfl.ch/

Researchers Reveal The Multi-Dimensional Universe Of The Brain

The human brain is a convoluted labyrinth of passages in constant flux - routes are being created, strengthened, and deconstructed on a daily basis. On top of this, there are billions of neurons communicating with each other all day, every day via these ever-changing passages. At their junctions, there are synapses - about 1 quadrillion of them. If this all sounds complicated enough, then add a mind-boggling 11 dimensions to the mix.

Get ready, this new research is set to be a head-twister.

The study, published in Frontiers in Computational Neuroscience, uses algebraic topology to reveal the multi-dimensional architecture of the brain. This branch of mathematics harnesses abstract algebra to study topological spaces, such as spheres, knots, and tori.

The team from Blue Brain Project primarily focused on “cliques” and “cavities” to paint a picture of the structures and spaces within the brain. When neurons form a clique, they connect to every other neuron in the group in a way that forms a precise geometric object. The more neurons there are in a clique, the more connections there are, and the greater the dimension of the object.

“We found a world that we had never imagined,” said neuroscientist Henry Markram, director of Blue Brain Project, in a statement, “there are tens of millions of these objects even in a small speck of the brain, up through seven dimensions. In some networks, we even found structures with up to eleven dimensions. ”

The purpose of such work is to try to peel back the relatively flat representation of the brain we have and reveal the multi-dimensional internal workings of the brain.

A representation of the neurons and connections that, in terms of the model, make up multi-dimensional "cliques". Above is a 5-dimensional simplex. Blue Brain Project When the team then added a stimulus into the virtual brain, progressively higher dimensional cliques assembled and enclosed holes, or cavities. Much of these developments, however, were ephemeral.

Co-author Ran Levi paints it in a simpler fashion: “The appearance of high-dimensional cavities when the brain is processing information means that the neurons in the network react to stimuli in an extremely organized manner. It is as if the brain reacts to a stimulus by building then razing a tower of multi-dimensional blocks, starting with rods (1D), then planks (2D), then cubes (3D), and then more complex geometries with 4D, 5D , etc. The progression of activity through the brain resembles a multi-dimensional sandcastle that materializes out of the sand and then disintegrates. ”

The team did their best to verify their findings by testing the results on real brain tissue. They state that their virtual discoveries were biologically relevant and suggest that the brain constantly rewires itself during development to construct a high-dimensional structure.

It is key to note that the objects in this study are not more than three dimensions outside the space of this model, it's just that the mathematics used to describe the intricacy can have more dimensions.

Researchers reveal the multidimensional universe of the brain

The human brain is a labyrinth coiled with passages in constant flow: the roads are created, reinforced and deconstructed daily. In addition, there are billions of neurons that communicate every day, every day, through these ever-changing passages. At their junction, there are synapses: about 1 quadrillion of them. If all this seems complicated enough, add incredible 11 dimensions to the mixture.

Prepare yourself, this new research should be a head-twister.

The study, published in Frontiers in Computational Neuroscience, uses an algebraic topology to reveal the multidimensional architecture of the brain. This branch of mathematics exploits abstract algebra to study topological spaces, such as spheres, nodes and tori.

The Blue Brain Project team mainly focused on "clicks" and "cavities" to paint a picture of structures and spaces in the brain. When the neurons form a click, they connect to all the other neurons in the group so as to form a precise geometric object. The more neurons there are in a click, the more connections there are and the larger the size of the object.

“We have found a world we never imagined,” said neurologist Henry Markram, director of Blue Brain Project, in a statement, “there are tens of millions of these objects, even in a tiny bit of end of the brain, through seven dimensions. In some networks, we have even found structures with up to eleven dimensions. "

The goal of this work is to try to eliminate the relatively flat representation of the brain that we have and to reveal the multidimensional internal functioning of the brain.

A representation of neurons and connections which, in model terms, constitute multidimensional "cliques". Above is a 5 dimensional simplex. Blue Brain Project When the team then added a stimulus to the virtual brain, progressive cliques gradually assembled and closed holes, or cavities. Much of these developments, however, were fleeting.

Co-author Ran Levi paints it in a simpler way: “The appearance of high-dimensional cavities when the brain processes information means that the neurons in the network react to stimuli in an extremely organized way. It's as if the brain reacts to a stimulus by building and then destroying a tower of multidimensional blocks, starting with rods (1D), boards (2D), then cubes (3D), then more complex geometries with 4D, 5D, Etc. The progression of activity through the brain resembles a multidimensional sandcastle that materializes out of the sand and then decays.

The team did their best to verify their results by testing the results on real brain tissue. They claim that their virtual discoveries were biologically relevant and suggest that the brain constantly replaces itself during development to build a large-scale structure.

It is essential to note that the objects in this study are not more than three dimensions outside the space of this model, it is simply that the mathematics used to describe complexity can have more dimensions.

We may have found an alternative to alcohol and drugs to better ... flirt : Cheesy:

The neurons of dominance

By artificially activating a particular brain area, researchers have transformed a fearful male into a dominant swollen confidence ... in mice.

What if it was enough to activate a few neurons to transform a fearful introvert into a dominant male, swollen with confidence? In any case, this has been achieved with Tingting Zhou mice from the Shanghai Biological Sciences Institute and his colleagues.

By recording the brain activity of pairs of rodents placed face to face in a tube, the researchers detected neurons that were more active when dominant behaviors (such as pushing each other). Using so-called optogenetic techniques, they then artificially activated these neurons in dominated males, who then imposed their law, forcing their congener to retreat into the tube.

The neurons discovered are located in the dorsomedial prefrontal cortex, an area involved in the evaluation of costs and benefits, as well as in that of the efforts required. This type of more or less conscious analysis could therefore well underlie the adoption of dominant behaviors.

A whole new kind of optical illusion makes us see, in places, curvatures, angles or both. It is called the illusion of curvature blindness. A professor in experimental psychology shows us a telling example.

A CNRS study has just appeared, it shows the link between too much sugar in adolescence and depressive phenomenon and decrease in neurogenesis in adults ... for rats at least ...

http://www.cnrs.fr/insb/recherche/parut ... cador.html

Too much sugar in adolescence: risk of depression in adulthood?

Adolescence is a critical time for the developing brain. Neuroscientists from the University of Bordeaux have shown that unlimited consumption of sucrose in rats during adolescence disrupts brain plasticity, motivation and emotional behavior in adulthood. The changes observed are corrected by chronic treatment with an antidepressant. These results raise the question of the potential deleterious effects of overconsumption of food or sugary drinks on brain maturation and mental health in adulthood.

The brain during adolescence is still maturing and therefore particularly sensitive to the environment. However, adolescence is characterized by an often excessive consumption of drugs, alcohol, but also foods very rich in sugar (sodas, industrial foods), the latter can represent up to 20% of the daily portion in calories. . However, the consequences of overconsumption of sugar during adolescence on the brain remain very poorly understood.

Researchers from the INCIA Addicteam team (CNRS) have developed a preclinical project over the past few years on the long-term effects of sugar consumption during adolescence. They have shown, in collaboration with NutriNeuro (INRA), that unlimited access to a sugar solution (5%) during adolescence in rats produces in adulthood a decrease in motivation, an increase in type behaviors anxiety and immobility in the forced swimming test as well as a decrease in neurogenesis in the hippocampus. These alterations are classically interpreted as a signature of a “depressive” type condition in pre-clinical models.

In addition, chronic treatment with an antidepressant (imipramine) helps prevent the onset of neurobehavioral changes associated with overconsumption of sugar water during adolescence. The researchers are now interested in elucidating the neural circuits involved. These works have important societal implications since they suggest that an excessive consumption of foods rich in sugar (very rewarding) during adolescence modifies the cerebral development trajectory and favors the appearance of a depressive state in adulthood. .

“Teenage” rats (30 to 46 days old) had free access to two bottles: a bottle of water and a bottle of 5% sugar water. The preference for sugar water is immediate and the quantities drunk are very large (up to 4 times more than the usual consumption of water). In adulthood, rats that have consumed sugar water are less motivated to obtain a palatable reward, more anxious and more immobile in the forced swimming test. These effects are suppressed by chronic treatment with an antidepressant administered at the end of adolescence. In addition, in the brain, overconsumption of sugar in adolescence decreases adult hippocampal neurogenesis which is also normalized by the antidepressant.

An easier but certainly very effective illusion to prevent children (and older children) from running in the corridor of this hotel!
