In a significant advancement for neuroscience, researchers have unveiled new insights into how the human brain creates and retrieves memories. The research, led by Dr. Tomás Ryan at Trinity College Dublin, highlights the pivotal role of “engram cells”—a group of neurons that capture and store experiences through their connections. This discovery represents a paradigm shift from traditional views that memories reside within individual neurons. Instead, the focus is now on the dynamic and structural connections between these neurons, potentially transforming how we understand memory processing.

In an intriguing development, scientists are uncovering the intricate workings of the brain that signal when we need to eat or drink. A recent study conducted by the Max Planck Institute for Biological Intelligence, in collaboration with the University of Regensburg and Stanford University, has found critical insights into how specific neurons within the brain’s amygdala may drive our basic urges to eat and drink. This discovery not only adds depth to our understanding of these essential functions but also opens new avenues for tackling conditions like obesity, anorexia, and even addiction.
