The study may also shed light on the role of protein synthesis in long-term memory.
A new protein called mBDNF has been found to play a crucial role in forming long-term memories. The discovery opens up possibilities for studying the protein in people with disorders of learning and memory, as well as developing new medications to compensate for these problems.
Researchers found that the temporoammonic (TA) projection is crucial for the dialog between the hippocampus and cortex after learning, suggesting a window of vulnerability for memory consolidation. The study opens up new avenues for exploring the role of sleep in memory formation.
Research found that infants' sighs play a significant role in helping their lungs mature and regulate breathing. The study revealed that sighs may 'reset' the breathing mechanism, improving lung function and gas exchange efficiency. This suggests a crucial link between breathing control and mechanical development.
Researchers found that suppressing CBP function in adult rodents impaired long-term memory, but administering a histone deacetylase inhibitor corrected this defect. This suggests remodeling of chromatin is essential for learning and memory, and may offer new treatment options for cognitive disorders.
Researchers discover that drugs already being tested for cancer and Huntington's disease may help restore some memory capability to patients with RTS, a heritable disorder characterized by mental and growth retardation. The study found that restoring acetylation activity alleviates memory problems in mutant mice.
Researchers recorded activity of individual hippocampal neurons as monkeys retrieved well-learned information from memory, finding stronger response to familiar stimuli. The study provides strong evidence for a memory signal specific to well-learned information and may inform treatments for Alzheimer's Disease.
The study reveals a direct activational signal from the synapse to the protein synthesis machinery, enabling neurons to boost protein production rapidly during long-term memory formation and synaptic strengthening. This discovery has significant implications for understanding psychiatric and neurologic diseases, potentially leading to ...
Researchers found that regular ecstasy users experienced mainly long-term memory difficulties and were 23% more likely to report problems than non-users. Those who also used cannabis reported up to 20% more memory problems due to the 'double whammy' effect.
Researchers found a marker for long-term immunity in CD8 T cells using the interleukin 7 (IL-7) receptor. This discovery can help scientists create more effective vaccines and develop new treatments for chronic viral infections and cancer.
A team of researchers has identified an enzyme, protein kinase C, that may play a crucial role in turning fleeting experiences into lasting memories. The study found that this enzyme helps to activate genes that express proteins involved in forming long-term memories.
A research team at NYU has identified cells in the hippocampus that signal new memory formation, shedding light on how associations are formed in the brain. The discovery is a major breakthrough in understanding the brain basis of memory and could lead to new treatments for Alzheimer's disease.
Researchers at USF and VA hospitals found that rats with intrusive emotional memories can't remember new information. They also exhibited behavioral symptoms similar to those in people with PTSD after being reminded of the traumatic experience.
Researchers at Cold Spring Harbor Laboratory identified 92 unique fruit fly memory genes that could be important for understanding human learning and memory. The study found that many of these genes have counterparts in humans and may be potential targets for developing therapies to treat Alzheimer's disease.
A study of German children found that exposure to airport noise was linked to reading deficits and impaired long-term memory. However, the effects were reversible once the local airport closed, suggesting that a quieter environment can mitigate the negative impacts of noise on children's cognitive abilities.
A study published in Psychological Science found that German children exposed to airport noise showed significant declines in reading and memory abilities. However, these effects were reversible once the local airport closed, indicating that exposure to chronic noise can have serious health and learning impacts on children.
A team of researchers has identified a key enzyme involved in the consolidation of long-term memories, revealing new insights into the molecular processes underlying learning and memory. The study found that eliminating this enzyme led to impaired memory retention, highlighting its critical role in memory consolidation.
Shiffrin's work has evolved over 35 years, developing Bayesian approaches to model human memory, attention, and learning. His theories have been widely recognized with numerous awards and publications.
A Rutgers study published in Nature found that people can build strong visual memories for scenes with limited exposure and recall more objects over time. The research suggests that medium-term memory plays a key role in this process, allowing individuals to quickly identify their surroundings without constant visual scanning.
Researchers found that the brain replays and reinforces initial learning events to create cell-to-cell connections for long-term memories. This process, called synaptic reentry reinforcement, may be crucial for maintaining stable information over time.
Researchers found that long-term memories become labile every time they are retrieved, making them susceptible to alteration or disruption. The process of reconsolidation, which involves the generation of new proteins, is necessary to store long-term memories without retrieval.
