Scientists found that blocking microglia prevents infant forgetting and improves memory in mice, suggesting a role for microglia in memory formation. Microglia inhibition also enhances engram cell activation, providing a functional explanation for enhanced memory recall.
A study of 676 patients who experienced out-of-hospital cardiac arrest found that neurological outcomes were similar regardless of socioeconomic background. However, lower-income areas had lower bystander CPR rates, suggesting disparities in pre-hospital care.
Researchers found that Parkinson's disease symptoms on one side of the body can predict cognitive decline and psychiatric disorders. The study analyzed 80 studies to demonstrate the critical importance of personalized care tailored to individual disease profiles.
Researchers developed HippoCamera, a new smartphone app that significantly improves memory recall by boosting attention to daily events. Users record videos and audio descriptions of everyday experiences, which are then replayed to reinforce memory consolidation.
A new study suggests that supplementing a diet with Ascidiacea, also known as sea squirts, reverses some main signs of aging in animal models. The researchers found that plasmalogens, vital to body processes, decrease with age and contribute to neurodegenerative diseases like Alzheimer's and Parkinson's.
A new brain imaging study reveals that infants use the hippocampus to recognize patterns, despite limited episodic memory, with the brain region doubling in size between 2-4 years old
In a study published in PNAS, researchers found that when participants were informed they could return some of the money they had overreported, they forgot their past cheating behavior more accurately. This 'unethical amnesia' allowed them to restore their reputation, making it more acceptable for future moral breaches.
Scientists have long struggled to explain the 'Great Unconformity,' a phenomenon where ancient rocks sit atop much younger sediment. New research suggests that multiple smaller events may have triggered these unconformities worldwide. The findings could help better understand the origins of complex life during the Cambrian Explosion.
A study by Harvard Medical School researchers found that the measles virus depletes antibody repertoires, erasing immune memory to most previously encountered pathogens. This supports the immune amnesia hypothesis, suggesting that the vaccine's extended protective effects stem from preventing measles infection.
A new study found that women athletes are 50% more likely to suffer a sports-related concussion than their male counterparts. The research, which analyzed data from 1,203 college athletes over a four-year period, also revealed that women take longer to recover from the injury, with an average return-to-play time of 10 days.
Despite medical community's understanding of brain function, the double-trauma amnesia cure belief persisted due to anecdotal evidence and flawed theories. A French scientist named Francois Xavier Bichat proposed the idea that a second blow could restore memories in the late 18th century, but his claims were not backed by specific cases.
A new IU study found that many college students enjoy feeling scared while playing video games, with 44.1% of participants reporting they enjoyed the experience. The researchers also discovered that interactivity, darkness, and disfigured humans were common factors causing fear in gamers.
Researchers from the RIKEN-MIT Center for Neural Circuit Genetics demonstrated that traces of old memories remain in the amnestic brain and can be reactivated, allowing lost memories to be found. The study suggests that past memories may not be erased but lost and inaccessible for recall.
A new study reveals that measles can suppress the immune system for up to three years, making children highly vulnerable to other infectious diseases. The research, published in Science, provides epidemiologic evidence that measles attacks immune memory cells, leading to a state of 'immune amnesia'.
A UT Dallas researcher challenged a long-held scientific theory about the role of the hippocampus in unconscious memory. The study used EEG to test brain wave patterns in amnesia patients with damaged hippocampuses, revealing that the hippocampus is involved in processing unconscious memories.
Scientists tested 100 undergraduate students in a memory experiment and found that even simple pieces of information were often forgotten when not expected. However, participants performed better when the information was relevant to their current task. This suggests that people's expectations play a significant role in determining what...
A recent study challenges the idea that individuals with episodic amnesia are unable to understand time, revealing they retain temporal consciousness and can order events on a timeline. This discovery opens up new questions about memory and its relationship to human understanding of time.
A new study published in The Journal of Pediatrics found that children who suffer from more severe concussion symptoms tend to have longer recovery times. Researchers analyzed data from 182 patients and identified the total score on the Post-Concussion Symptom Scale as a key predictor of prolonged recoveries.
A study by the American Orthopaedic Society for Sports Medicine found that athletes wearing properly fitted helmets were 82% less likely to experience loss of consciousness due to concussions. Helmet fit was not associated with a significant impact on concussion severity, but proper air bladder inflation was.
A 22-year-old woman with amnesia demonstrated that her short-term memory is impaired when trying to recall new information. However, she showed no difficulty recalling familiar faces or words.
People with declarative memory impairment have trouble making common ground in conversation due to their inability to form new declarative memories. In the study, participants with amnesia looked equally at two elephants, showing no benefit from earlier conversations.
Research from Northwestern University found that 50% of college drinkers report at least one alcohol-induced memory blackout in the past year. Students who experienced these blackouts were more likely to suffer alcohol-related injuries, highlighting the need for better screening and interventions.
Brown University political scientist Ross Cheit disputes a 2006 Harvard University psychiatric contest on repressed memory, arguing that the methodology was flawed and no data correction was issued after discovering a pre-1800 literary example fulfilling the criteria
Researchers found that thinking about similar experiences accelerates recovery from satiation, as people tend to forget the variety they had in their lives. By recalling past favorite experiences, consumers can regain enjoyment and appreciate their current experience more.
Researchers discovered distinctive activity differences in specific brain areas of hypnosis-susceptible individuals, which showed suppressed or increased activity during memory suppression and recall. The study suggests that hypnosis may model forms of amnesia by affecting an early executive decision on retrieval.
Researchers re-examine the nature of amnesia, questioning whether it's a defect in memory storage or recovery. They propose novel experimental approaches to evaluate the neurobiological basis of memory impairment, building on existing studies of amnesia.
Researchers studied participants under the influence of midazolam and a saline placebo to understand memory formation. They found that recollection was impaired by midazolam, while familiarity remained unaffected.
A recent study using diffusion weighted imaging found small brain lesions appearing on MRI scans of amnesiac patients within hours and days of onset. The lesions were all located in the hippocampus, a key area for memory functions, suggesting a possible cause for transient global amnesia.
A University of Pittsburgh study found that prior concussions may lower the threshold for subsequent concussion injury and increase symptom severity in seemingly mild subsequent concussions. The research, which compared 60 athletes with no prior concussion history to 28 athletes with three or more concussions, showed a significant incr...
Researchers at Johns Hopkins Medicine discovered that bearing down hard during sex can cause transient global amnesia, a temporary inability to form new memories. The study found two cases of men experiencing confusion and amnesia after sex, linked to the Valsalva maneuver and sympathetic nervous system activation.
