A new UI study reports a potential link between stress hormones and short-term memory loss in older adults. The study, published in the Journal of Neuroscience, reveals that having high levels of cortisol—a natural hormone in our body whose levels surge when we are stressed—can lead to memory lapses as we age.
Signed, sealed, and delivered: The University of Iowa welcomed a new magnetic resonance imaging instrument, one of the world's most sophisticated models to date, that will advance research into the human brain and body.
A magnetic resonance imaging instrument weighing 42 tons—equal to six adult male elephants—arrives on Thursday, June 5, at the University of Iowa. The 7 Tesla magnet will advance UI research by yielding clearer, higher-resolution images of the human brain. The UI is one of only about 20 research institutes in the United States—and only about 40 worldwide—with the instrument. It also is the most powerful magnetic imaging device in the state.
Researchers at the University of Iowa say that damage to a region of the brain, the left temporal pole, may be associated with difficulty recalling auditory stimuli, such as the title to a song. The finding supports the theory that the left temporal pole is important for naming unique items, from landmarks to song names. Results published in the journal Neuropsychology.
University of Iowa researchers show that the hippocampus is involved in language processing, possibly providing additional insight into how to treat people with Alzheimer’s disease. Results appear in the Journal of Experimental Psychology.
Two demographic trends in Iowa—an aging population and workers staying on the job later in life—will have a significant impact for employers and employees in the years ahead. University of Iowa neuroscientist Steven Anderson will offer his perspective during an April 29 presentation in Des Moines.
Next time something you hear goes in one ear and out the other, you have a built-in excuse. Just blame it on your Achilles' ear—a weakness that lies not in a mythical hero's heel, but in the real-life way the brain processes sound and memory, according to new UI research.
