Elderly Clumsiness Brain Changes
2013-06-06 08:01:08

redOrbit Staff & Wire Reports - Your Universe Online Often attributed to age-related decay in vision and physical prowess, incidents of clumsiness in seniors could actually be caused by changes in the brain, researchers from Washington University in St. Louis claim in a new study. Incidents in which older men and women have difficulty reaching for and/or grasping things, such as inability to dial a phone of knocking over a glass while attempting to grab a different object, could be...

Paying Attention To Error Keeps Your Motor Memories Alive
2013-06-04 15:47:04

Brett Smith for redOrbit.com - Your Universe Online A new study by researchers at Johns Hopkins School of Medicine in Baltimore has found that people who can´t see their errors when performing a physical task will lose that skill, not because the brain forgets, but because it has selected an inadequate technique. The study, which is published in the Journal of Neuroscience, focused on the idea of “motor memories,” or the body´s ability to know the amount of force...

Smell and touch, sniffing and 'whisking,' are locked in sync When animals are on the hunt for food they likely use many senses, and scientists have wondered how the different senses work together. New research from the laboratory of CSHL neuroscientist and Assistant Professor Adam Kepecs shows that when rats actively use the senses of smell (sniffing) and touch (through their whiskers) those two processes are locked in synchronicity. The team's paper, published today in the Journal of...

Adding movement to mental rehearsal can improve performance finds a study in BioMed Central's open access journal Behavioral and Brain Functions. For high jumpers the study shows that dynamic imagery improves the number of successful attempts and the technical performance of jumps. The technique of mental rehearsal is used to consolidate performance in many disciplines including music and sport. Motor imagery and physical practice use overlapping neural networks in the brain and the two...

How The Brain Affects Quick Judgments In Social Settings

April Flowers for redOrbit.com - Your Universe Online We make snap judgments about other people all the time, whether we like to admit it or not. In speed dating, this is especially true because we are deciding someone's romantic potential in relatively few seconds. How we make those fast decisions is not very well understood, however. A research team from the California Institute of Technology (CALTECH) and Trinity College, Dublin has found that people make such speed-dating...

A hallmark of human intelligence is the ability to efficiently adapt to uncertain, changing and open-ended environments. In such environments, efficient adaptive behavior often requires considering multiple alternative behavioral strategies, adjusting them, and possibly inventing new ones. These reasoning, learning and creative abilities involve the frontal lobes, which are especially well developed in humans compared to other primates. However, how the frontal function decides to create...

Findings establish a model to study how the brain processes multisensory information, a process that goes awry in autism spectrum disorders The next time you set a trap for that rat running around in your basement, here's something to consider: you are going up against an opponent whose ability to assess the situation and make decisions is statistically just as good as yours. A Cold Spring Harbor Laboratory (CSHL) study that compared the ability of humans and rodents to make perceptual...

We like to think of ourselves as rational creatures, absorbing information, weighing it carefully, and making thoughtful decisions. But, as it turns out, we´re kidding ourselves. Over the past few decades, scientists have shown there are many different internal and external factors influencing how we think, feel, communicate, and make decisions at any given moment. One particularly powerful influence may be our own bodies, according to new research reviewed in the December issue of...

What happens in the brain of right-handed people if their dominant hand is immobile for two weeks? This is the question addressed in the latest study led by Professor Lutz Jäncke and the Trauma Surgery Department at Zurich University Hospital. For the study, ten right-handed people with broken upper right arms were examined. Because of the plaster or sling, the test people's right hands were restricted to little or no movement for fourteen days. Therefore they used their left...

Researchers discover how the brain merges sights and sounds In order to get a better picture of our surroundings, the brain has to integrate information from different senses, but how does it know which signals to combine? New research involving scientists from the Max Planck Institute for Biological Cybernetics, the Bernstein Center for Computational Neuroscience Tübingen, the University of Oxford, and the University of Bielefeld has demonstrated that humans exploit the...


Word of the Day
out-herod
  • In the phrase to out-herod Herod, to be more violent than Herod (as represented in the old mystery plays); hence, to exceed in any excess of evil.
Herod refers to 'Herod the Great,' a Roman client king and 'a madman who murdered his own family and a great many rabbis.' According to the OED, the term is 'chiefly with allusion to Shakespeare's use' in Hamlet.
