New research from the University of Copenhagen shows that noradrenaline causes brief wake-ups during sleep, potentially leading to better memory and less anxiety. High levels of noradrenaline result in brief awakenings, while low levels promote deeper sleep.
A joint UC Riverside and UC Irvine study found that people who show near transfer in brain training are more likely to experience far transfer, meaning improved focus and problem-solving skills. The research suggests that working memory training can be effective for certain individuals, but its impact on fluid intelligence remains deba...
Researchers discovered two novel categories of cells in the BLA that respond to ethological stimuli, including event-specific neurons responding to one type of stimulus and panresponsive neurons responding equally well to multiple stimuli. These findings suggest a larger role for the BLA in memory and behavior.
Research published in eNeuro found that physical consequences, such as slipping, can improve motor learning by refining movement responses to mistakes. Participants who experienced a slip improved their ability to adjust steps to new situations, demonstrating better generalization of learned skills.
Researchers identified a key brain circuit in the anterior thalamus that helps us hold information in mind. In a study of mice, enhancing this circuit's activity improved their ability to navigate a maze and reversed memory loss with artificial stimulation.
A study found that infants aged 5-8 months preferentially perceive faces in the upper visual field. The bias emerges around 7 months and is specific to faces, with no observed bias for non-face images. This suggests an important role of experience with faces in daily life in shaping this perceptual bias.
A new study by MIT researchers confirms that a single memory is stored across many connected brain regions, challenging long-held assumptions. The study used advanced imaging techniques to map memory encoding and recall activity in mice, revealing dozens of brain regions involved in memory storage.

Researchers find that familiar stimuli quiet down brain activity in fruit flies, allowing for clearer processing of specific odors. This mechanism applies to neural circuits in other animals, including humans, and is essential for filtering out distractions to focus on relevant information.
A study published in Trends in Cognitive Sciences found that older adults tend to store irrelevant information, making it harder to remember specific details. This can lead to a 'flood' of information, but also benefits like improved prior knowledge utilization and decision-making.
A recent study at Rockefeller University reveals that the FMRP protein plays a dual role in regulating synaptic connections between neurons. It controls protein production in dendrites to strengthen connections, while also regulating gene expression in cell bodies to maintain overall neuron state.
Researchers found that males keep track of the order of their songs and how often each one is sung for up to 30 minutes. This complex behavior allows them to curate both their current playlist and the next one, with variations in song order and repeats.
A study published in iScience reveals that distorted perception of bodily self-consciousness can be predicted by different kinds of memories. The researchers found that the recovery of body ownership was associated with a fast memory process, while agency recovery was mainly linked to a slow memory process.
The study found that memories of objects from stressful situations rely on similar brain activity as memories of the stress trigger itself. This suggests that the mechanism reinforcing emotional memories is rooted in the neural link between important aspects of the episode and the stress trigger.
A new study by University of Leicester neuroscientists argues that the way humans store memories is key to our superior intelligence. Contrary to long-held beliefs, the same group of neurons stores all memories, enabling abstract thinking and cognitive abilities unique to humans.
A recent study by Aarhus University researchers reveals that citizens contribute significantly to the spread of negative information about politicians, leading to increased mistrust. This phenomenon is rooted in humans' innate psychological tendency to prioritize self-interest over political substance.
Researchers used repetitive transcranial magnetic stimulation to increase functional connectivity of a neural network implicated in memory. The study, published in eNeuro, confirms the effectiveness of this technique for experimental and clinical applications.
