The answer to how your brain knows when you’ve had enough to drink and can stop feeling thirsty may have been found in a new UC San Francisco study. Until recently, scientists believed that a brain region called the hypothalamus makes us thirsty when it detects a drop in the hydration of our blood. But… Read more

MIT neuroscientists have uncovered a cellular pathway that allows specific synapses to become stronger during memory formation. The findings provide the first glimpse of the molecular mechanism by which long-term memories are encoded in a region of the hippocampus called CA3. The researchers found that a protein called Npas4, previously identified as a master controller… Read more

The ventrolateral prefrontal cortex (VLPFC), part of the prefrontal cortex, is located on the inferior frontal gyrus, bounded superiorly by the inferior frontal sulcus and inferiorly by the lateral sulcus, being attributed to the anatomical structures of Brodmann’s area (BA) 47, 45 and 44 (considered the subregions of the VLPFC – the anterior, mid and… Read more

The ‘sonic hedgehog’ gene, best known for controlling embryonic development, also maintains the normal physiological state and repair process of an adult healthy lung, if damaged, according to new research from the Perelman School of Medicine at the University of Pennsylvania. Tissues are not all created equal in their ability to regenerate. Skin and blood… Read more

What gives the world’s most elite sprinters—those that compete in the 100, 200, 400, and 800-meter races—their speed? It’s all in the knees. Researchers were interested to know why Jamaica, with a population smaller than that of Los Angeles, is home to so many of the world’s elite sprinters. Previous research had shown that the… Read more
