Researchers have discovered how two brain areas, neocortex and thalamus, work together to detect discrepancies between what animals expect from their environment and actual events. These prediction errors are implemented by selective boosting of unexpected sensory information. These findings enhance our understanding of predictive…

Among the many ways neuroscientists think Alzheimer’s disease may strip away brain function is by disrupting the glucose metabolism needed to fuel the healthy brain. In essence, declining metabolism robs the brain of energy, impairing thinking and memory. Against that backdrop, a team of…

Sleep works magic on memory. You might’ve felt these frustrations before: Trying to learn a guitar riff, shoot a free-throw, or nail a difficult phrase in a new language, but despite hours of practice, you’re just not getting it right. Then with a good…
A new study from Cornell University reveals that sleep not only consolidates memories but also resets the brain’s memory storage mechanism. This process, governed by specific regions in the hippocampus, allows neurons to prepare for new learning without being overwhelmed. This insight opens potential…
A good night’s sleep is crucial for helping people make new memories: Neurons that capture new memories during the day reset while you sleep, researchers reported. Photo by Adobe Stock/HealthDay News A good night’s sleep is crucial for helping people make new memories, a…
While everyone knows that a good night’s sleep restores energy, a new Cornell University study finds it resets another vital function: memory. Learning or experiencing new things activates neurons in the hippocampus, a region of the brain vital for memory. Later, while we sleep,…
