Researchers René Marois and J. Jay Todd found that the human brain's visual short-term memory has a limited storage capacity of about four objects. This is attributed to the posterior parietal cortex, which plays a key role in holding information from visual scenes.
Researchers found that regular ecstasy users experienced mainly long-term memory difficulties and were 23% more likely to report problems than non-users. Those who also used cannabis reported up to 20% more memory problems due to the 'double whammy' effect.
Researchers found that Concord grape juice improved short-term memory and neuro-motor skills in senescent rats, with significant improvements seen in tests measuring spatial learning and balance. The study suggests that high levels of natural antioxidants in the grape juice may be responsible for these benefits.
Researchers at Duke University Medical Center found a link between nerve cell changes and the apolipoprotein E4 gene. Those with the APOE4 gene experienced more rapid loss of nerve cell functioning, leading to accelerated brain aging. This study may lead to new understanding of age-related memory loss and potentially sharper brains.
Research by University of Michigan cognitive neuroscientist Patricia Reuter-Lorenz found that older adults activate both hemispheres of the brain to perform memory and information processing tasks. This bi-hemispheric processing may help compensate for age-related short-term memory and mental speed declines.
Researchers discover that dopamine levels can enhance or impair working memory, with a low dose of the drug bromocriptine improving scores in low-capacity subjects but worsening performance in high-capacity individuals. The study suggests an optimal level of dopamine for short-term memory to function properly.
