University of Kentucky Study: Healthy Dietary Intake Associated With Lower Brain Iron, Better Cognition in Older Adults
Research conducted at the University of Kentucky College of Medicine suggests that higher intake of specific nutrients is associated with lower brain iron concentration and better cognitive performance in older adults.
Humans are born with brains ‘prewired’ to see words
Humans are born with a part of the brain that is prewired to be receptive to seeing words and letters, setting the stage at birth for people to learn how to read, a new study suggests.
Longitudinal Study of Brain Aging and Cognitive Change Receives $19 Million Grant
Researchers at UC San Diego School of Medicine, with colleagues elsewhere, will receive almost $19 million over five years for the fourth phase of the Vietnam Era Twin Study of Aging, which investigates cognition, aging and the risk for mild cognitive impairment and Alzheimer’s disease.
Study Traces Brain-to-Gut Connections
Using rabies virus injected into the stomach of rats, researchers trace the nerves back to the brain and find distinct “fight or flight” and “rest and digest” circuits. These results explain how mental states can affect the gut, and present new ways to treat gastrointestinal problems.
Why myelinated mammalian nerves are fast and allow high frequency
With novel patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier, researchers have found unexpected potassium channels that give the myelinated nerve the ability to propagate nerve impulses at high frequencies and with high conduction speeds.
