Infantile amnesia: Gauging children's earliest memories
Previous research has established that adults experience infantile amnesia -- an inability to recall the earliest years of their lives. Now a new longitudinal study of 140 children ages 4 to 13 explores infantile amnesia in children. In the study, children were asked to recall their earliest memories. Younger children showed more change in recalling earliest memories over time; older children showed more consistency in recalling earliest memories over time. (2011-05-11)

New research shows reactivating single memory does not affect associated memories
Researchers at a trio of universities have found that reactivating a specific memory does not affect associated or related memories, adding to our understanding of how memories are stored and influenced. The study appears in the latest issue of the Proceedings of the National Academy of Sciences. (2006-02-13)

Research identifies a way to block memories associated with PTSD or drug addiction
New research from Western University could lead to better treatments for Post-Traumatic Stress Disorder (PTSD) and drug addiction by effectively blocking memories. The research by Nicole Lauzon and Steven Laviolette has identified a common mechanism in a region of the brain called the pre-limbic cortex, which can suppress the recall of memories linked to both aversive, traumatic experiences associated with PTSD and rewarding memories linked to drug addiction, without permanently altering memories.

Seeing it both ways: Visual perspective in memory
Think of a memory from your childhood. Are you seeing the memory through your own eyes, or can you see yourself, while viewing that child as if you were an observer? (2019-08-27)

False memories of crime appear real when retold to others
People are no better than chance at identifying when someone else is recounting a false or real memory of a crime, according to a new UCL study published in Frontiers in Psychology. (2020-04-08)

Scientists show hippocampus's role in long term memory
A team of scientists led by NYU Professor of Neural Science Wendy Suzuki have proven that the hippocampus is involved in the retrieval of long-term memor by recording the activity of individual hippocampal neurons in animals. The research forms the necessary first steps towards developing treatments for devastating memory-related diseases such as Alzheimer's. (2004-05-12)

Study reveals fundamental insight into how memory changes with age
New research from King's College London and The Open University could help explain why memory in old age is much less flexible than in young adulthood. Through experiments in mice the researchers discovered that there were dramatic differences in how memories were stored in old age, compared to young adulthood. (2019-10-17)

Brain rehearsal time ensures lasting memory performance
University of Alberta researchers have established that the ability of the brain to rehearse or repeat electrical impulses may be absolutely critical in order to make a newly acquired memory more permanent. (2012-02-14)

Scientists identify that memories can be lost and found
A team of scientists believe they have shown that memories are more robust than we thought and have identified the process in the brain, which could help rescue lost memories or bury bad memories, and pave the way for new drugs and treatment for people with memory problems. (2015-08-04)

Discovery of two opposite ways humans voluntarily forget unwanted memories
If only there were a way to forget that humiliating faux pas at last night's dinner party. It turns out there's not one, but two opposite ways in which the brain allows us to voluntarily forget unwanted memories, according to a study published by Cell Press October 17 in the journal Neuron. The findings may explain how individuals can cope with undesirable experiences and could lead to the development of treatments to improve disorders of memory control. (2012-10-17)

Microglia regulate forgetting in the adult brain
The ability to forget our memories -- for better or worse -- is dependent on microglia and their inclination to weaken and eliminate the synapses connecting engram neurons, according to a new study in mice. (2020-02-06)

Activation of a protein solidifies fear memory in the brain
When activated, a specific protein in the brain enhances long-term storage of fearful memories. (2006-01-23)

Sleep makes your memories stronger
Scientists have found that sleep helps consolidate memories, fixing them in the brain so we can retrieve them later. Now, new research is showing that sleep also seems to reorganize memories, picking out the emotional details and reconfiguring the memories to help you produce new and creative ideas, according to the authors of an article in Current Directions in Psychological Science, a journal of the Association for Psychological Science. (2010-11-12)

How odors are turned into long-term memories
Neuroscientists from the Ruhr-Universität Bochum have investigated which brain area is responsible for storing odours as long-term memories. Some odours can trigger memories of experiences from years back. The current study shows that the piriform cortex, a part of the olfactory brain, is involved in the process of saving those memories; the mechanism, however, only works in interaction with other brain areas. (2017-12-22)

Memory strategy may help depressed people remember the good times
New research highlights a memory strategy that may help people who suffer from depression in recalling positive day-to-day experiences. The study is published in Clinical Psychological Science, a journal of the Association for Psychological Science. (2013-02-25)

Disrupted REM sleep can derail memory formation
A new study in mice provides direct causal evidence that rapid eye movement or REM sleep helps to consolidate memory in the brain. (2016-05-12)

Familiar songs act as strong memory cues, K-State researcher finds
Memories associated with music are strong. So strong that even the mere mention of a song's title or a glimpse of the album cover can bring the recollections of a time or place flooding back. (2005-05-26)

Virtual brain gives insights into memory deficits in depression
During a depressive episode the ability of the brain to form new brain cells is reduced. Scientists of the Ruhr-Universität Bochum examined how this affects the memory with a computational model. It was previously known that people in an acute depressive episode were less likely to remember current events. The computational model however suggests that older memories were affected as well. How long the memory deficits reach back depends on how long the depressive episode lasts. (2018-06-08)

Drugs that weaken traumatic memories hold promise for PTSD treatment
Memories of traumatic events often last a lifetime because they are so difficult to treat through behavioral approaches. A preclinical study in mice published by Cell Press Jan. 16 in the journal Cell reveals that drugs known as histone deacetylase inhibitors can enhance the brain's ability to permanently replace old traumatic memories with new memories, opening promising avenues for the treatment of post-traumatic stress disorder and other anxiety disorders. (2014-01-16)

Brain caught 'filing' memories during rest
Memories formed in one part of the brain are replayed and transferred to a different area of the brain during rest, according to a new UCL study in rats. The finding suggests that replay of previous experiences during rest is important for memory consolidation, a process whereby the brain stabilises and preserves memories for quick recall in the future. Understanding the physiological mechanism of this is essential for tackling amnesiac conditions such as Alzheimer's disease, where memory consolidation is affected. (2016-04-18)

Differences in recovered memories of childhood sexual abuse
When a child experiences a traumatic event it may not be until well into adulthood that they remember the incident. It's unknown how adults are able to retrieve long-forgotten memories of abuse and there has been some controversy as to the authenticity of these reports. A new study suggests that there are important differences between people who gradually recover memories of abuse during suggestive therapy sessions and those who recover memories of abuse more spontaneously. (2009-02-02)

Similarity breeds proximity in memory, NYU researchers find
Researchers at New York University have identified the nature of brain activity that allows us to bridge time in our memories. Their findings offer new insights into the temporal nature of how we store our recollections and may offer a pathway for addressing memory-related afflictions. (2014-03-05)

Sleep makes our memories more accessible, study shows
Sleeping not only protects memories from being forgotten, it also makes them easier to access, according to new research from the University of Exeter and the Basque Centre for Cognition, Brain and Language. (2015-07-26)

Can sleep protect us from forgetting old memories?
Researchers at University of California San Diego School of Medicine report that sleep may help people to learn continuously through their lifetime by encoding new memories and protecting old ones. (2020-08-04)

Researchers use light to beat amnesia in mice
Memories that have been destabilized and forgotten by mice can nevertheless be retrieved by activating memory engrams, or specific patterns of neurons that fire when memories are encoded, with light, researchers say. (2015-05-28)

Sleep helps process traumatic experiences
If we sleep in the first 24 hours after a traumatic experience, this may help process and integrate the distressing memories more effectively, as researchers from the University of Zurich and the Psychiatric University Hospital Zurich demonstrate in a new study. Sleep could thus be used as an early prevention strategy for post-traumatic stress disorders. (2016-12-13)

WSU researchers see way cocaine hijacks memory
Washington State University researchers have found a mechanism in the brain that facilitates the pathologically powerful role of memory in drug addiction. Their discovery opens a new area of research for targeted therapy that would alter or disable the mechanism and make drug addiction less compulsive. (2015-03-10)

MIT team reports new insights on animal dreams
Memories of our life stories may be reinforced while we sleep, MIT researchers report December 17 in the advance online edition of Nature Neuroscience. (2006-12-18)

Remembrance of smells past
Smells trigger memories but can memories trigger smell, and what does this imply for the way memories are stored? A UCL study of the smell gateway in the brain has found that the memory of an event is scattered across sensory parts of the brain, suggesting that advertising aimed at triggering memories of golden beaches and soft sand could well enhance your desire to book a seaside holiday. (2004-05-26)

How cortisol reinforces traumatic memories
The stress hormone cortisol strengthens memories of scary experiences. However, it is effective not only while the memory is being formed for the first time, but also later when people look back at an experience while the memory reconsolidates. This has been published by cognition psychologists from the Ruhr-Universität Bochum in the journal Neuropsychopharmacology. They suggest that the results might explain the persistence of strong emotional memories occurring in anxiety and post-traumatic stress disorder. (2015-07-01)

Scientists uncover how brain retrieves and stores older memories

Artificial Intelligence beats us in chess, but not in memory
A new piece of research shows that the brain strategy for storing memories may lead to imperfect memories, but in turn, allows it to store more memories, and with less hassle than AI. The new study, carried out by SISSA scientists in collaboration with Kavli Institute for Systems Neuroscience & Centre for Neural Computation, Trondheim, Norway, has just been published in Physical Review Letters. (2021-01-15)

Where unconscious memories form
A small area deep in the brain called the perirhinal cortex is critical for forming unconscious conceptual memories, researchers at the UC Davis Center for Mind and Brain have found. (2010-12-15)
