A new glimpse into working memory

Study finds bursts of neural activity as the brain holds information in mind, overturns a long-held model. When you hold in mind a sentence you have just read or a phone number you’re about to dial, you’re engaging a critical … Continue reading

Brain waves guide memory formation

Neurons hum at different frequencies to tell the brain which memories it should store. Our brains generate a constant hum of activity: As neurons fire, they produce brain waves that oscillate at different frequencies. Long thought to be merely a … Continue reading

Molecular basis for Memory and Learning: Brain development and plasticity share similar signaling​ pathways

Learning and memory are two important functions of the brain that are based on the brain’s plasticity. Scientists now report on how a trio of key molecules directs these processes. Their findings provide new leads for the therapy of Alzheimer’s … Continue reading

An unpleasant emotional state reduces working memory capacity

Emotional states can guide the actions and decisions we make in our everyday life through their influence on cognitive processes such as working memory (WM). We investigated the long-lasting interference that an unpleasant emotional state had on goal-relevant WM representations … Continue reading

Theories of Memory and Aging: A Look at the Past and a Glimpse of the Future

The present article reviews theories of memory and aging over the past 50 years. Particularly notable is a progression from early single-mechanism perspectives to complex multifactorial models proposed to account for commonly observed age deficits in memory function. The seminal … Continue reading

Neural networks plasticity help the integration of new information

The human brain has a region of cells responsible for linking sensory cues to actions and behaviors and cataloging the link as a memory. Cells that form these links have been deemed highly stable and fixed. Now, the findings of … Continue reading

Long-term stress erodes memory

Sustained stress — such as that experienced in bad marriages or when working for a beastly boss — erodes memory, and the immune system plays a key role, according to a new study. Sustained stress erodes memory, and the immune … Continue reading

Health Check: can your brain be ‘full’?

The brain is truly a marvel. A seemingly endless library, whose shelves house our most precious memories as well as our lifetime’s knowledge. But is there a point where it reaches capacity? In other words, can the brain be “full”? The … Continue reading

How the brain consolidates memory during deep sleep

Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question … Continue reading

Your Brain doesn’t contain memories, it is Memories

Recall your favorite memory: the big game you won; the moment you first saw your child’s face; the day you realized you had fallen in love. It’s not a single memory, though, is it? Reconstructing it, you remember the smells, … Continue reading
