How we recall the past

Neuroscientists discover a brain circuit dedicated to retrieving memories. When we have a new experience, the memory of that event is stored in a neural circuit that connects several parts of the hippocampus and other brain structures. Each cluster of … Continue reading

Blocking a key enzyme reverse memory loss

In the brains of Alzheimer’s patients, many of the genes required to form new memories are shut down by a genetic blockade, contributing to the cognitive decline seen in those patients. MIT researchers have now shown that they can reverse … Continue reading

Expectation may be essential to memory formation

A theory that links memory encoding to expectations of future relevance may better explain how human memory works, according to a team of Penn State psychologists. Modern psychology posits two major theories to explain the mechanisms of how memories are … Continue reading

The Age-Related Memory Decline

A new study reports increased levels of STEP in the hippocampus is linked to mild cognitive impairment. In mice, rats, monkeys, and people, aging can take its toll on cognitive function. A new study by researchers at Yale and Université … Continue reading

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
