Memory justifications remain reliable over time, BGU study finds

A new study published in Communications Psychology found that verbal justifications supporting memories remain rich, detailed, and consistent even after a delay of 24 hours. The study suggests that memory justifications provide a temporally stable window into episodic memory, making them a reliable basis for evaluating memory credibility.

Brain research: “Pulse generators” grow and shrink as memories are formed

Scientists have observed changes in brain cells' signal transmission during learning processes, shedding light on the brain's adaptability. The study found that axon initial segments, responsible for generating electrical signals, can lengthen or shorten in response to experiences, influencing neuronal activity.

Night waking impacts cognitive performance regardless of sleep duration

A new study published in Sleep Health found that the quality of a night's sleep, rather than its length, predicts how quickly older adults process information the next day. Researchers analyzed data from 261 participants aged 70 and above, who wore devices to track their sleep and completed cognitive assessments six times a day.

Hierarchical temporal processing in the primate thalamocortical system: insights from nonlinguistic structured stimuli

The study demonstrates the auditory cortex's ability to integrate fine-scale and coarse-scale temporal cues during synchronization, with better performance in macaques compared to the middle glandular body. The nonlinguistic oddball paradigm shows promise for clinical applications in psychiatric disorders and future research should exp...

Researchers identify the molecular mechanisms linking early-life environments with memory

Researchers identified a molecular mechanism linking early-life environments with memory by activating AP-1, which regulates genes involved in neuronal plasticity and learning. Early-life experiences produce long-lasting modulation of AP-1 activity, boosting gene networks that strengthen neuronal connections.

Exploring how storytelling strategies shape memories

A new study found that storytelling strategies with conceptual or perceptual details activate distinct brain networks, predicting how well participants recall core elements of the story. This suggests that people's preferred memory systems may vary across age groups, and tailored information could improve memory for older adults.

Deep sleep supports memory via brain fluid and neural rhythms

Researchers have discovered that deep sleep plays a crucial role in controlling cerebrospinal fluid dynamics, which is essential for clearing waste from the brain. During slow-wave sleep, changes in cerebrospinal fluid signals are time-locked to slow brain waves and other neural events.

Astrocytes are superstars in the game of long-term memory

A new study reveals that astrocytes, a type of glial cell, are responsible for stabilizing memories through repeated engagement. The researchers found that Fos activity in astrocytes only occurs during recall, and that these cells can be activated to produce stable memories.

Researchers uncover why mental maps fade with age

Researchers found that older mice showed less stable spatial memory and difficulty navigating between familiar and unfamiliar environments. In contrast, younger mice developed distinct firing patterns for each track, allowing them to remember hidden reward locations on alternating tracks with ease.

Tiny worms reveal big secrets about memory

Researchers have found that tiny worms can help understand how memories fade, with dopamine playing a major role. Without dopamine, the worms held onto memories longer than usual, revealing that forgetting is a finely tuned process essential for staying focused and flexible.

Dental fear is widespread—But most people want treatment

A new study found that nearly three out of four adults suffer from dental fear, with 45.8% experiencing moderate fear and 26.8% severe fear. Most individuals interested in overcoming their fear are open to free, brief treatment options, such as virtual dental fear treatments using apps and telehealth.

Automatized vocabulary knowledge in predicting speech fluency

A new study by Waseda University researchers suggests that learners need to automatize word meanings in context to achieve fluent speech. By assessing automatized vocabulary knowledge (AVK) and declarative vocabulary knowledge (DVK), the team found AVK to be a stronger predictor of L2 speaking fluency.
