Neural efficiency hypothesis confirmed

Researchers confirm the neural efficiency hypothesis, which suggests that intelligent brains require less cortical activation to solve tasks. The study found that highly intelligent individuals required fewer resources to complete moderately difficult tasks, but not very easy or very difficult ones.

Brain activity after smokers quit predicts chances of relapsing, Penn study suggests

A Penn Medicine study suggests that disruptions in brain memory-related activity after quitting can identify smokers at risk of relapsing. Smokers who failed to quit had decreased activity in the left dorsolateral prefrontal cortex and reduced suppression of activation in the posterior cingulate cortex, indicating a higher chance of re...

Spice up your memory

A study published in the Asia Pacific Journal of Clinical Nutrition found that adding one gram of turmeric to breakfast improved working memory in older adults with pre-diabetes. The spice's active compound, curcumin, has been shown to reduce the risk of dementia and improve cognitive function.

Kessler Foundation multiple sclerosis researchers find role for working memory in cognitive reserve

Researchers at Kessler Foundation found that working memory capacity explains the relationship between intellectual enrichment and long-term memory in individuals with MS. This suggests that interventions targeting working memory may help build cognitive reserve to protect against decline in long-term memory.

'Noisy' memory in schizophrenia

Researchers found that schizophrenia patients exhibit altered brain activity in the ventro-lateral prefrontal cortex, leading to impaired ability to control working memory. This deficit is characterized by increased activation of irrelevant information, hindering cognitive function.

Simplicity is key to co-operative robots

Researchers have created a system of extremely simple robots that can cluster together without requiring complex computation. This development enables the creation of large numbers of robots to perform tasks collectively, with potential applications in precision farming and healthcare technologies. The robots use minimal information an...

Study reveals workings of working memory

Researchers at Brown University discovered that working memory uses similar brain circuits to those involved in planning motion. They found that the caudate and dorsal anterior premotor cortex contribute to output gating, a crucial process for selecting from working memory. The study's findings provide insight into how the brain effici...

How memory and schizophrenia are connected

A study published in Neuron reveals a connection between genes controlling neuronal excitability and working memory, psychiatric disease, and brain activity. The researchers identified a network of genes that plays a crucial role in human brain function, highlighting the importance of understanding its dysfunction in schizophrenia.

Younger people have 'high definition' memories

Researchers found that younger adults outperform older adults in visual working memory tasks, with a higher capacity for 'high definition' recall. This suggests that while older adults may store similar amounts of information, their memories are less detailed and impaired in recollection.

Motor excitability predicts working memory

A study by researchers from the University of Basel found that individuals with high motor excitability have better working memory than those with low excitability. The research used transcranial magnetic stimulation to measure motor cortical excitability and its correlation with working memory performance, revealing a positive correla...

A look inside children's minds

Researchers used fNIRS to study 3- and 4-year-old children's visual working memory, finding that neural activity in the right frontal cortex is linked to higher capacity, while 4-year-olds show increased use of the parietal cortex for spatial attention. The findings could help detect childhood disorders like ADHD and autism earlier.

Aerobic exercise boosts brain power

Aerobic exercise has been shown to improve cognitive function in older adults, including task switching, selective attention, and working memory. The evidence suggests that regular physical activity can attenuate age-related decline in these areas, providing a simple means for people to optimize their brain power.
