- Maladie d’Alzheimer : une découverte majeure de l’Inserm ()
Cette découverte peut être majeure dans la lutte contre la maladie d’Alzheimer. L’Inserm de Lille a mis en évidence l’un des mécanismes qui annonce le développement de la maladie. Les chercheurs ont tracé le rôle des tanycytes, des cellules déterminantes dans le diagnostic. https://www.youtube.com/watch?v=F1KZN1kFLRU
- Silent Neurons… ()
Researchers have discovered that memories we thought were lost are often not destroyed but stored in “silent” brain cells. These neurons stop responding to normal recall cues, yet they still retain the memory. By using a technique that activates specific neurons, scientists were able to turn on these dormant cells and bring back memories that […]

Brain engineering will really help the cryonics world over time, and brain engineering is just begining.. Knowledge about and playing with the brain will help us all.
- The MICrONS Project ()
An unprecedented dataset of high resolution anatomical images of individual cells in mouse visual cortex, mapped on to their responses. This integrated view of function and structure lays a foundation for discovering the computational bases of cortical circuits. A cubic millimetre might not sound like much — roughly the size of a grain of sand […]
- Brain Scans of Infants Reveal the Moment We Start Making Memories ()
A giggling toddler in a pink dress and matching headphones lies down on her back in front of a gigantic whirling machine. A pillowy headrest cushions her head. She seems unfazed as she’s slowly shuttled into the claustrophobic brain scanner. Once settled, a projection showing kaleidoscope-like animations holds her attention as the magnetic resonance imaging […]
- Scientists have found a way to help the brain learn faster using AI to guide brain activity directly. ()
Scientists have found a way to help the brain learn faster using AI to guide brain activity directly. Researchers from the University of Rochester, Yale, and Princeton have developed a method that uses real-time brain scans and neurofeedback to help the brain learn new things without any effort, practice, or study. It’s like giving your […]
- SCIENTISTS SAY NEW MATERIAL CAN RECONNECT SEVERED NERVES ()
n news that could be significant for patients with brain or nerve issues, researchers at Rice University have developed a new material that they say can stimulate neural tissue in a less invasive manner than previous treatments, and also allow nerve signals to flow again despite a severed connection. The research team at Rice says […]
- Why human brain cells grow so slowly ()
Some human neurons take years to reach maturity; an epigenetic ‘brake’ could be responsible. Growing human neurons in the lab can be a time-consuming process. Some cortical cells take years to reach maturity – many times slower than the equivalent cells in a mouse. Researchers have been exploring some of the mechanisms that could be […]
- Unique Flow of Information Identified in The Human Brain ()
Information doesn’t make its way around our brains in the same way as it does in the brains of other animals, according to a new study, and it could teach us something important about the way our species has evolved. A team led by researchers from the Swiss Federal Institute of Technology in Lausanne (EPFL) […]
- Electrical Zaps Woke Up Dormant Neurons to Help Paralyzed People Walk Again ()
What was science fiction is now scientific reality: with a series of targeted electrical zaps to the spinal cord, nine paralyzed people immediately walked again with help from a robot. Five months later, half of the participants no longer needed those zaps to walk. Does the sentence sound a bit familiar? By themselves, the results—while […]
- The brain undergoes a great “rewiring” after age 40 ()
In the fifth decade of life, our brains start to undergo a radical “rewiring” that results in diverse networks becoming more integrated and connected over the ensuing decades, with accompanying effects on cognition. The networking changes likely result from the brain reorganizing itself to function as well as it can with dwindling resources and aging […]
- New Brain Maps Can Predict Behaviors ()
Rapid advances in large-scale connectomics are beginning to spotlight the importance of individual variations in the neural circuitry. They also highlight the limitations of “wiring diagrams” alone. A 3D model of closely bundled pyramidal neurons running through cortical layer 5 of a mammalian brain; the neurons have been colored differently to distinguish them. Researchers have […]
- Subminiature multifunctional brain chip analyzes brain activity from multiple aspects ()
Neurotransmitters play a key role in the signal transmission process between neurons in the brain. If the concentration of neurotransmitters is higher or lower than normal, it triggers brain diseases for which neurotransmitters are injected as treatments. Therefore, the accurate measurement of neurotransmitter concentration is crucial for investigating the cause or during the treatment of […]
- An expanding molecular toolbox untangles neural circuits ()
Life is full of nervous reactions — a head snaps towards a voice, leg muscles tense at the sound of a starting gun and thirsty mice scamper towards a squirt of water when trained to respond to a certain tone. The mechanisms behind such reward-related behaviours are notoriously difficult to unpick. Nerve cells often snake […]
- Learning from imaging data to model brain activity ()
In this article, we introduce VanDEEPol, a hybrid AI/mechanistic model to predict brain activity and structure from imaging data. The model significantly boosts predictive accuracy compared to previous methods. By predicting brain activity from relatively sparse imaging data, VanDEEPol may eventually help to detect medical disorders or design brain-computer interfaces. Intricate interactions among billions of […]
