- Brain Waves Move in Opposite Directions For Memorizing And Recalling ()
Our squishy gray matter conducts its activities through an orchestra of waves. With many tasks operating in tandem, how our brain keeps distinct oscillations from tangling has long been a puzzle. Now US researchers have found the direction of traveling brain waves align with their type of task, with learning processes flowing one way and […]
- Forgetting: Not a Flaw, But a Brain’s Hidden Feature of Memory ()
Summary: Recent studies suggest that forgetting might not just be a mere oversight of our brains, but a dynamic response to our changing environments. Neuroscientists propose that as environments shift, forgetting irrelevant memories can foster adaptability and better decision-making. Experiments revealed that even after certain memories in mice seemed forgotten, they could be retrieved with […]
- Brain networks encoding memory come together via electric fields, study finds ()

- Organizing memories for generalization in complementary learning systems ()
Memorization and generalization are complementary cognitive processes that jointly promote adaptive behavior. For example, animals should memorize safe routes to specific water sources and generalize from these memories to discover environmental features that predict new ones. These functions depend on systems consolidation mechanisms that construct neocortical memory traces from hippocampal precursors, but why systems consolidation […]

- Most detailed map of brain’s memory hub finds connectivity puzzle ()
The most detailed map ever made of the communication links between the hippocampus—the brain’s memory control center—and the rest of the brain has been created by Australian scientists. And it may change how we think about human memory. “We were surprised to find fewer connections between the hippocampus and frontal cortical areas, and more connections […]
- A memory prosthesis could restore memory in people with damaged brains ()
A unique form of brain stimulation appears to boost people’s ability to remember new information—by mimicking the way our brains create memories. The “memory prosthesis,” which involves inserting an electrode deep into the brain, also seems to work in people with memory disorders—and is even more effective in people who had poor memory to begin […]
- How does the brain store memories? ()
Memory is one of the building blocks of the brain. It can help keep us safe — that red stove burner is hot, don’t touch it! — and forms the basis of our identities and narratives about our lives. So how does the brain store memories and retrieve them? The simplest answer is that the […]
- Scientists Watch a Memory Form in a Living Brain ()
While watching a fearful memory take shape in the brain of a living fish, neuroscientists see an unexpected level of rewiring occur in the synaptic connections. Imagine that while you are enjoying your morning bowl of Cheerios, a spider drops from the ceiling and plops into the milk. Years later, you still can’t get near […]

- How Our Environment Affects What We Remember ()
Summary: When successive experiences occur in the same environment, they become more deeply imprinted in our brain. Source: University of Amsterdam It is a common experience that, when you share memories with a friend, you can recount some events in much more detail than others, while other times, you mix up memories. But why do […]
- New Map of Meaning in the Brain Changes Ideas About Memory ()
Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory. In 2016, neuroscientists mapped how pea-size regions of the cortex respond to hundreds of semantic concepts. They’re now building on that work to understand […]
