The study reveals that emotional pictures are recalled better than neutral ones, and this recall is associated with increased activity in the amygdala and hippocampus. The researchers propose a synergistic mechanism where emotion triggers recollection, creating a loop that could help understand traumatic memory recall in PTSD patients.
Researchers found that brain activity in the hippocampus and perirhinal cortex predicts accurate or false memories. Weak prefrontal cortex activity during misinformation phase indicates poorly placed details, creating false memories.
A study by Patricia West and colleagues found that writing stories about paintings boosts writer's preference for a painting. Stories focusing on the author also show improved recall and enjoyment of the task. The authors argue that this effect applies to various consumer goods, such as clothing and family vacations.
A new fMRI study found that autobiographical memories engage different parts of the brain, even when recalling the same content. The study used 'diary' method to collect memories, revealing the frontal lobes involved in self-awareness and visual memory are more strongly activated for episodic memories.
A study published in Psychological Science used MRI technology to investigate how people form false memories. The researchers found that brain activity in specific areas, such as the precuneus and right inferior parietal cortex, was greater for words that were later falsely remembered as having been presented with photos. This suggests...

The researchers discovered a significant correlation between activity in emotion- and memory-related brain regions during emotional memory formation.
Researchers at UCL's Institute of Neurology found that memories are distributed across different brain regions, not just one area. This means that a single sense can reactivate a memory, rather than requiring all aspects to be recreated.
Researchers found that the piriform cortex was activated when subjects saw objects previously associated with odors, confirming models of memory recall. The hippocampus draws on these sensory components to reconstruct rich memories.
New research suggests two distinct brain areas, the hippocampus and subiculum, work together to process and store information for short-term memory. This finding broadens understanding of how memory works and could lead to more sensitive tests and treatments for conditions like Alzheimer's disease.
Researchers have discovered that the anterior cingulate cortex plays a crucial role in storing and retrieving lifelong memories. The study, led by Dr. Paul Frankland, found that older memories are transferred from the hippocampus to the cortex over several weeks, likely during sleep.
Researchers at UCLA deciphered the mystery of distant memory recall using a three-pronged experiment. They found that the anterior cingulate plays a special role in keeping early memories alive, while kinase II is critically involved in preserving our oldest memories.
Researchers have discovered that a brain electrical signal can predict an individual's visual working memory capacity, which varies from 1.5 to 5 objects. The study found that the signal levels off when the number of objects exceeds the subject's capacity, while those with higher capacity show large increases in brain activity.

The study suggests targeting cognitive 'stress tests' to detect early dementia symptoms and discourages chronic use of medications with anticholinergic effects.
Researchers found a significant bias against recovered memories, with an average rating of 3.6 compared to 4.0 for continuous memories. This bias may be caused by imprecise terminology and misleading media reports, which can harm victims of child abuse.
Scientists have identified a biological basis for suppressing unwanted memories, contradicting human intuition that people ruminate on unpleasant thoughts. The study found that controlling memory is associated with increased activation of the frontal cortex and reduced activation of the hippocampus.
Researchers found that unwanted memories can be suppressed using brain areas similar to those used during physical action control. This process reduces hippocampal activity, leading to forgetfulness. The study provides a novel neurobiological model for motivated forgetting, which may demystify how repression occurs.

Researchers have made advances in understanding false memories by identifying brain areas activated in true versus false memories. The right fusiform area was found to be more active in encoding objects that were later labeled as the same as those seen earlier, but less active when they were only similar or actually the same.
A study by Ohio State University researchers found that participants were more likely to incorrectly identify a similar image as part of the original set, even though it was not present. This suggests that visual false memories can be induced using context, challenging our perceptions and memory recall.
Researchers have found that the right fusiform area is more active when participants recognize objects as similar to those seen earlier, but less active when they correctly label them as new. This suggests that the right fusiform area plays a role in encoding specific visual details and may help reduce false memories.
Researchers at Weizmann Institute have identified a new principle guiding brain memory systems, explaining inconsistencies in previous studies. This discovery may lead to the development of new methods for wiping out unwanted memories and treating psychological trauma.

A Hong Kong study found that music instruction aids verbal memory, with trained students recalling significantly more words and retaining them longer than untrained peers. Verbal learning performance improved in proportion to musical training duration.
Researchers found that active involvement in forming an idea, known as generative learning, reduces false memory. Participants were more likely to accurately remember words from a list they created themselves than those presented by others.
A study by W. Richard Walker and colleagues found two causes for positively biased recollection of the past: pleasant events outnumber negative ones and memory treats pleasant emotions differently from unpleasant ones. This fading affect bias allows people to cope with tragedies, celebrate joyful moments, and look forward to tomorrow.
Researchers found that musicians remembered music better when they heard it during learning, regardless of whether they heard the music when replayed it later. This contradicts matching theories and suggests that auditory feedback plays a crucial role in music memory.
Researchers have identified a phenomenon where TV viewers misremember facts from news stories, often due to stereotypical thinking. To combat this, they suggest using semantic elaboration to promote critical thinking. By displaying the wrong-doer's face before or alongside the news anchor, false memories can be corrected.
A study found that heavy drinkers with fragmentary blackouts misremember drinking experiences while expecting positive outcomes. This phenomenon can contribute to problem drinking by reinforcing distorted beliefs about alcohol's effects.

This finding has implications for the treatment of traumatic brain injuries, highlighting the potential benefits of brain imaging studies in tracking changes and understanding recovery.
Researchers at Baylor College of Medicine found that the CA3 region of the hippocampus is essential for 'pattern completion', allowing memories to be recalled from partial representations. The study involved genetically engineered mice with impaired NMDA receptor function in the CA3 region, which displayed deficits in memory recall.
The study suggests that objects are recalled by uniting different brain regions, with the thalamus regulating electrical rhythms to connect these areas. This theory may help explain why some memories are clear while others are fuzzy.

The positive effects on memory are explained by an evolutionary perspective, suggesting specific types of food energy enhance specific aspects of brain function.
Research suggests that people with left-handed families tend to have superior episodic memory due to increased inter-hemispheric interaction. This is because their brain hemispheres work together more actively to process and store memories, leading to improved recall of events.
