A study from the University of East Anglia explores how our brains remember past events and how those memories can change over time. Memories are made up of different parts and can become less accurate or include new information as they are retrieved.
Studies show that the cerebellum is critical for forming stable memories for sensorimotor skills, largely independent of short-term memory systems. Researchers found that longer time intervals between trials increased reliance on impaired long-term memory.
Researchers found that exercise increased neuron growth in the hippocampus, rewiring neural circuits to help mice forget strong, traumatic memories. This approach may offer new treatments for PTSD and drug addiction.
Researchers found that electrical signals in the hippocampus differ immediately before recalling true and false memories. The study used epilepsy patients to measure neural activity leading up to correct or false recall, revealing a reduction in low-frequency activity associated with contextual similarity.
Researchers at Florida Atlantic University found that mice can perceive the difference between a picture of an object and the actual 3D object, employing higher-order cognitive processes. The study suggests that mice's hippocampus plays a significant role in associating memories with visual stimuli.
Researchers investigate potential treatments for improving cognition in infants, including engineered gut microbes to counter antibiotic-exposure effects. A choline supplement is also being studied as a treatment for prenatal alcohol exposure-related cognitive impairments.
A study published in the journal Aging, Neuropsychology, and Cognition found that children who attend school for longer periods have better memory abilities in old age, particularly for women. More years of early-life education counteract age-related memory losses, suggesting a protective effect against Alzheimer's disease.
Research finds that trauma-exposed individuals, regardless of PTSD status, struggle with suppressing memories. Neuroimaging data reveals reduced activation in the right middle frontal gyrus, a critical region for memory suppression, among trauma-exposed participants.
A study published in Neuropsychologia found that both conscious and unconscious emotional suppression reduce participants' memory of negative images. However, explicit emotional suppression has a greater impact on reducing negative emotions associated with the images.
Research proposes that a brain system called declarative memory compensates for autism, OCD, and dyslexia by providing strategies to overcome learning difficulties. This compensation allows individuals to learn scripts for social situations and control tics and compulsions.
Researchers found that the brain separates emotional responses from explicit memories of fear, leading to uncontrolled emotional reactions in post-traumatic stress disorder. This study may help develop new therapeutic strategies for these disorders.
Researchers found that rats with no explicit memory of an early childhood trauma developed PTSD symptoms, highlighting the importance of non-articulated brain processes in distress. This study challenges traditional views on PTSD treatment by emphasizing the role of physiologic arousal and other forms of learning.
A new UCSB study published in the Journal of Neuroscience reveals that paying full attention and trying hard can impede performance. The study found that disrupting explicit memory resources, which are associated with conscious thought, can harm implicit memory processes, leading to poorer performance outcomes.
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.
A study found that amnesics remember grammar but not the meaning of new sentences, indicating separate components for language function. The researchers suggest syntactic knowledge is a specialized skill akin to riding a bike, shaped by basic memory mechanisms.
A study published in the journal SLEEP found that a brief daytime nap (45 minutes) benefits declarative memory performance. The results suggest that there is a threshold acquisition level required for sleep to optimally process memories, and this finding has implications for adults' nightly sleep recommendations.
A study by Universitat Autonoma de Barcelona found that the prelimbic prefrontal cortex plays a crucial role in social transmission of food preference. This discovery sheds new light on the functioning of declarative memory, which is affected in Alzheimer's disease.
Researchers found that girls use a system for memorizing words and associations, while boys rely on rule-governed language systems. The study supports the notion that men and women may process skills differently, with estrogen affecting brain processing.
The study found that explicit and implicit memory are strongly linked during encoding of new information, as measured by brain signal patterns. Researchers observed a reduction in brain activation when photos were viewed again, indicating repetition attenuation and a signature of implicit memory.
Researchers found that individuals with Korsakoff Syndrome retain visual learning ability despite explicit memory impairment. Visuoperceptual learning, a component of implicit memory, was shown to be preserved in KS patients.
A new study found that alcoholics show deficits in visuoperception and frontal executive functioning even with prolonged sobriety. Researchers assessed visuoperception and perceptual learning tasks in detoxified alcoholic men compared to control men, revealing differences in cognitive processes and memory strategies.
Researchers found that older adults with Alzheimer's symptoms can still use implicit memory to perform tasks, similar to young adults. By training these individuals using repetition and practice, their performance can be improved, according to a new study.
A study using MRI found that procedural learning and declarative learning activate the same neural networks, despite requiring different levels of awareness. The brain's prefrontal cortex, inferior parietal cortex, and putamen were active in both cases, suggesting a shared underlying network.
A study found that participants who watched TV programs with sex or violence had impaired memory for advertised products compared to those who watched neutral programs. The results suggest that sex and violence can impair commercial memory, potentially deterring advertisers from sponsoring such content.
