Scientists have developed nanoparticles that, when injected into the eye, can restore vision after retinal damage by replacing lost photoreceptors. This technology does not require surgery and is suitable for various causes of vision loss.
A new study has shown that the front and back regions of the brain develop from different types of stem cells, challenging previous beliefs. This discovery has made it possible, for the first time, to grow brainstem neurons in the laboratory and opens up new opportunities for researching and treating serious diseases.
Studies have shown that humans can recognize scents as quickly as rodents, thanks to an ancient evolutionary mechanism in the brain. This discovery could aid in the early diagnosis of diseases associated with impaired sense of smell.
A new study has shown that the APOE2 gene variant helps neurons protect DNA and slows down cellular aging, thereby reducing the risk of dementia and Alzheimer's disease. These findings open up new possibilities for therapeutic approaches, especially for people with a high genetic risk.
A new study has shown that even under deep anesthesia, the brain is still able to distinguish the meaning of heard words and analyze speech. These findings expand our understanding of unconscious perception and memory function.
Scientists have demonstrated that miniature brain models grown from the cells of patients with Alzheimer's disease can help predict individual responses to treatment and identify new disease biomarkers. This approach paves the way for more precise and personalized therapies.
American neurobiologists have demonstrated that artificially reproducing brain activity typical of sleep in awake mice can help restore memory without the need for full sleep. In the future, researchers plan to test this method on humans, but for now, it is not possible to completely replace sleep.
Scientists have identified a specific neural circuit in the brain that plays a key role in anxiety and social isolation. Restoring balance in this circuit in mice reduced symptoms of anxious and depressive behavior, opening up new possibilities for the treatment of affective disorders.
Новое исследование показало, что обонятельные нейроны в носу мышей организованы в четкие полосы по типу рецептора, а не распределены случайно. Это открытие может помочь в разработке методов восстановления обоняния у людей.
Long-term studies have shown that some people over the age of 80 maintain memory and mental sharpness at a level comparable to much younger individuals. Examining their brains and lifestyles helps us understand the mechanisms behind resilience to dementia and may lead to new strategies for preventing age-related cognitive decline.
A new study has found that depression is linked to changes in certain types of brain cells responsible for mood and immune functions, opening up possibilities for new treatment methods.
The ketogenic diet helps reduce the frequency of seizures in epilepsy by altering metabolism and brain neuron activity. Recent studies are uncovering the molecular mechanisms behind this effect and opening up new possibilities for developing innovative treatment methods.
Chinese researchers have unveiled the LightGen photonic chip, which is capable of running large-scale AI models with performance up to 100 times greater than leading GPUs, while significantly reducing energy consumption.
A new study has shown that gut bacteria from primates with large brains can activate genes in rodents related to energy supply and cognitive functions, which may have played a role in the evolution of intelligence.
Scientists have developed a minimally invasive wireless neuroimplant capable of directly transmitting sensory signals to the brain. This technology opens up new possibilities for restoring lost senses and aiding rehabilitation after injuries and illnesses.
