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.
A new study has shown that when choosing between risk and safety, two independent regions of the cortex interact in the brain. This discovery helps to better understand the nature of doubt and could lead to new methods for treating anxiety disorders.
Researchers have developed a method to reconstruct videos based on the brain activity of mice, opening up new possibilities for studying how the brain transforms visual signals into internal representations. This work provides deeper insight into the differences between objective reality and the way the brain perceives the world.
Inhaling the aroma of dark chocolate before and during strength training can increase the number of repetitions performed and reduce feelings of hunger, without causing additional fatigue. However, this effect requires further research.
A new study has shown that speaking multiple languages can slow down brain aging: for bilingual people, the brain appears up to 6 years younger, while for those who speak four languages, it can look up to 13 years younger. This effect is even stronger if language learning begins early and proficiency is high.
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.
Experiments have shown that consuming fast food at an early age disrupts the connection between the stomach and the brain in rats, leading to impaired spatial memory even after returning to a healthy diet.
A study has shown that cats can perceive the emotional tone of human speech, but they are unable to distinguish specific emotions based solely on voice. To accurately understand a person's mood, they likely also need visual cues.
A new study has shown that parental care in animals is based on ancient neural mechanisms related to hunger control. Evolution has repurposed existing feeding regulation systems to shape parental behavior.
The experiment showed that dogs are more likely to help people in order to receive a treat, rather than out of altruistic motives. The presence of the owner or a stranger had little effect on their behavior.
A new study has revealed that linguistic diversity on Earth reached its peak several thousand years ago and has been rapidly declining ever since. Today, nearly 40% of the world's languages are at risk of disappearing.
A new study has shown that both dogs and wolves are able to detect the scent of human fear, and their reactions to it are similar. This suggests that such sensitivity has ancient origins, likely developing in the common ancestor of these species.
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.
International studies have shown that the mysterious low-frequency hum heard by millions of people is most often an internal noise generated by the auditory system, rather than an external sound. This phenomenon is linked to the unique workings of human hearing.
