Even before we begin exploring the world, the brain may have a kind of internal map, “like a GPS,” ready to guide us. This hypothesis, which is still under investigation, fascinates Norwegian neuroscientist May-Britt Moser, the 2014 Nobel Prize in Physiology or Medicine laureate, who has spent decades trying to unravel how we know our way around.

“It seems that we could have an internal map that is ready for us when we start moving and exploring,” Moser said in an interview with EFE, although she cautioned that the findings she is currently working on have not yet been published.
Moser refers to philosopher Immanuel Kant and the possibility that, to experience the world, the brain needs certain pre-existing structures that allow it to organize what it perceives.
"I was not always the best student… but my teachers saw something in me."

But Did Those Structures Exist?
The neuroscientist is now trying to determine whether one of these structures exists before an animal — rats, in her case — begins moving around and learning about its surroundings.
The clue comes from so-called “grid cells,” which Moser discovered with her husband, Edvard Moser. Their discovery helped the couple share the Nobel Prize with British neuroscientist John O’Keefe.
These neurons fire in a highly regular “spatial pattern.” When the locations where a single cell fires as a rat moves around are plotted, equilateral triangles can be drawn between its different activity fields.
Moser said she remains surprised by this level of precision, precisely because the brain is a biological system and, therefore, one might expect much more noise and many more errors.
“Because the brain is a biological system, you would expect many errors. And if there were many errors, we would never see a pattern like the one we observe in grid cells, where equilateral triangles can fit between each activity field as the animal moves through its surroundings. It is incredible,” she stressed.
The geometry becomes even stranger when scientists simultaneously record the activity of numerous grid cells and use mathematical tools to represent it in three dimensions.
What emerges is a “torus,” a doughnut-shaped surface across which neuronal activity appears to move, a kind of map that would not switch off even when the outside world disappears.
“This internal map is active even when the animal sleeps, so it does not need any information from the outside to keep functioning. It is simply the way the cells are connected that makes this pattern possible,” she said, adding that the question remains whether this architecture, or scaffolding, exists before exploration begins.
Moser is confident that the combination of new technologies capable of recording thousands of neurons, better mathematical theories and computational models will make it possible to achieve major advances in understanding the brain over the coming years.
"This is not biology! You can't get this in biology!"

The Mystery of Feeling Alive
“But, as Professor Geoffrey Hinton, considered the ‘godfather’ of AI, said, understanding how we can come to have that feeling of being alive, of being conscious, can be quite difficult,” Moser reflected.
Artificial intelligence could become a tool for investigating this question, in part because it makes it possible to compare how a machine and a brain perform similar functions.
Asked whether she is optimistic about AI or a “doomer” — a term for someone who takes a catastrophic view of its future — Moser said that losing hope means surrendering. “But I think we need hope,” the neuroscientist replied.
In her view, tools can be used both to do good and to cause harm, and artificial intelligence does not eliminate this long-standing human trait, although it can greatly amplify its consequences, she added.
“It becomes dangerous if evil people use the tool to become even more evil. But they can also use their brains to be evil,” she said.
Against an international backdrop that she describes as “depressing” when she watches the news, Moser champions cooperation, science and education. She also points to individuals capable of mobilizing many others, from Malala Yousafzai to Greta Thunberg and Jane Goodall.
Thus, despite this depressing situation, Moser does not see machines as having intellectual supremacy, either. “For now, I think the brain is the best tool we have,” she concluded.

On Thursday evening, the Greek parliament approved legislation banning children under 15 from accessing social media from Jan. 1, 2027.

The legislation requires social media platforms to implement age-verification measures to ensure compliance. Companies that fail to meet the requirements could face fines of up to 6 percent of their global annual turnover.
Addressing parliament ahead of the vote, Digital Governance and Artificial Intelligence Minister Dimitris Papastergiou described the measure as a necessary step that is compatible with the European Union’s (EU) existing regulatory framework.
“It would have been very easy to do absolutely nothing today and wait for the perfect European law. But the challenge is here. Children are sinking into the internet every day, and I believe a responsible government must do what it is obliged to do,” he said.

Minister of State Akis Skertsos said technology should be regulated in ways that give children greater freedom to grow up safely.
Excessive use of social media can negatively affect children’s sleep, concentration, social relationships and psychological development, said Health Minister Adonis Georgiadis, who described digital addiction as a public health challenge.
The legislation forms part of broader government efforts to protect children from harmful online content, cyberbullying and platform features that encourage excessive use. Greece aims to become the first EU member state to introduce such a ban.
The French parliament passed legislation on July 21 aimed at protecting minors from the risks associated with social media use. However, the French Constitutional Council ruled on Aug. 14 that the key provision banning under-15s from accessing social media was unconstitutional.

On Thursday, polling firm Datafolha published a survey showing far-right candidate Flavio Bolsonaro and Brazilian President Luiz Inacio Lula da Silva tied at 50% of valid votes, three days before the presidential runoff.

This is the first runoff poll to show a numerical tie between the two candidates and represents a two-point recovery for Lula compared with the survey released by the same firm last week.
In terms of voter intention, Bolsonaro has 47%, compared with Lula’s 46%, representing a one-percentage-point increase for the incumbent.
On Wednesday, another poll released by Quaest also showed a trend toward a narrowing gap between the two candidates, in this case with Bolsonaro leading by one point, 45% to Lula’s 44%.

In both polls, the results amount to a statistical tie within the margin of error, which is two percentage points for each survey. For its latest poll, commissioned by television network Globo and Folha de Sao Paulo, Datafolha interviewed 2,520 voters between Tuesday and Wednesday of this week.
Bolsonaro received the most votes in the first round of the presidential election, held Oct. 4, with 47.03% of the vote, followed by Lula with 45.16%. This was the narrowest result between two candidates in the first round of a presidential election held in Brazil, demonstrating the extreme polarization of the Brazilian electorate.
In Brazil’s recent democratic history, presidential runoffs have been held seven times, and in every instance, the candidate who received the most votes in the first round has won.
On Friday, Lula and Bolsonaro will face off in the second and final televised debate and will wrap up their respective campaigns on Saturday, the day before voters head to the polls.
