Memories are thought to be stored in sparse groups of neurons called engrams. These are the cells that switch on during learning and can later switch on again during recall. In physiological aging and ...

The hippocampus serves as the primary learning and memory center of the brain, but this is not where our memories are held. Rather, memory traces or engrams are represented by the connections between ...

Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their ...

These distinct tests enabled the scientists to observe specific hippocampal activity during learning and then memory replay and consolidation in sleep. Because of the way our pupils change in response ...

Researchers at Google have developed a new AI paradigm aimed at solving one of the biggest limitations in today’s large language models: their inability to learn or update their knowledge after ...

Researchers found that older adults learned a memory task best after practicing multiple related tasks, suggesting that diverse cognitive training supports mental sharpness as we age. When Ilber ...

Memories can form outside of the brain, according to new research. Non-brain cells exposed to chemical pulses similar to the ones that brain cells are exposed to when presented with new information ...

When Michelle D. Miller leads faculty workshops, she often does what she calls a “party trick” that she uses on the first day of class with her students: learning everyone’s names. As professors have ...

Your implicit memory helps you remember how to do things without consciously thinking about it. It includes skills and habits, like how to ride a bike and how to get around your house. It also ...

Retrograde amnesia is the inability to remember past experiences. It's different than anterograde amnesia, which is the inability to form new memories. Types of retrograde amnesia have different ...
