After treatment, the mice’s memories were essentially shunted back into a younger state. The researchers found that reprogrammed engrams displayed molecular behavior of more youthful cells. Using a ...

Age can make memory feel like something that only moves in one direction. A name slips away. A route you know well turns ...

Parvalbumin (PV) interneurons act as the brain’s rhythm keepers. By regulating local circuit activity and maintaining excitation–inhibition balance, they help stabilize cortical network function. When ...

Scientists exploring how the brain responds to stress discovered molecular changes that can influence behavior long after an experience ends. They also identified natural resilience systems that help ...

Our brains may work best when teetering on the edge of chaos. A new theory suggests that criticality a sweet spot between order and randomness is the secret to learning, memory, and adaptability. When ...

The human brain has 86 billion neurons connected by roughly 100 trillion synapses, making it one of the most complex objects in the known universe. Each year neuroscientists make fascinating, ...

Maternal immune activation reprograms the fetal brain, increasing alcohol-seeking behavior after adolescent exposure. Prenatal antioxidants act as a key preventive.
