Alzheimer’s Disease Destroys Neurons That Keep Us Awake

Researchers and caregivers have noted that excessive daytime napping can develop long before the memory problems associated with Alzheimer's disease begin to unfold. Prior studies have considered this excessive daytime napping to be compensation for poor nighttime sleep caused by Alzheimer's-related disruptions in sleep-promoting brain regions, while others have argued that the sleep problems themselves …

Memory And Attention Difficulties Are Often Part Of A Normal Life

From young adults to people in their 60s, everyday functioning in today’s world can place high demands on our attention and memory skills. Memory lapses such as forgetting an appointment, losing our keys, forgetting a distant relative’s name or not remembering why you opened the fridge can leave us believing our thinking skills are impaired. …

Perception Is Fundamentally Linked To Visual Working Memory

perception and working memory
Perception and thought are fundamentally linked, according to research from George Washington University. "We create a false separation between our perception of the world and the way that we're thinking about it. But actually these two things occur at the same time, in the same place, and as a result they interfere with each other. …

Can We Turn Down The Emotion On Traumatic Memories?

storing a fear memory
A small structure in the brain could hold the keys to future therapeutic techniques for treating depression, anxiety, and PTSD, someday allowing clinicians to enhance positive memories or suppress negative ones, according to Steve Ramirez, an assistant professor of psychological and brain sciences at Boston University. Inside our brains, a cashew-shaped structure called the hippocampus …

Sleep Contributes To System Long-term Memory Consolidation

hippocampus
Repeated rehearsal can lead to the establishment of memory traces in the neocortex within a short timeframe, new research demonstrates. However, these traces are only sufficiently stable if a sleep phase follows learning – otherwise the brain continuously needs to call on the hippocampus to help with long-term storage of new memories, the study found. …

Garlic May Decrease Deficits In Aging Related Memory

garlic
Eating garlic helps counterbalance age-related changes in gut bacteria associated with memory problems, a new study conducted with mice indicates. The benefits come from allyl sulfide, a compound in garlic known for its health benefits. "Our findings suggest that dietary administration of garlic containing allyl sulfide could help maintain healthy gut microorganisms and improve cognitive …

Brain Ripple Oscillations Occur Before Episodic Memory Retrieval

Coupled ripple oscillations between the medial temporal lobe and neocortex
Split seconds before we recall memories of past experiences, tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval, a study of epilepsy patients suggest. "We showed for the first time that ripples may be the neural substrates through which the …
