For an animal that has a brain about the size of two grains of sand, a lot of plasticity seems to be packed into the head of the tropical paper wasp Polybia aequatorialis. Researchers from the universities of Washington and Texas have found that the brain architecture of these wasps undergoes dramatic changes as they cycle through a sequence of specialized jobs during their lives. The scientists previously had discovered that parts of the brains of this wasp species enlarged as the animal...

Chaos brews in the brains of newborns: the nerve cells are still bound only loosely to each other. Under the leadership of Academy Research Fellow Sari Lauri, a team of researchers at the University of Helsinki has been studying for years how a neural network capable of processing information effectively is created out of chaos. The team has now found a new kind of mechanism that adjusts the functional development of nerve cell contacts. The results were published in early September as the...

When we absorb new information, the human brain reshapes itself to store this newfound knowledge. But where exactly is the new knowledge kept, and how does that capacity to adapt reflect our risk for Alzheimer's disease and other forms of senile dementia later in our lives?Dr. Yaniv Assaf of Tel Aviv University's Department of Neurobiology is pioneering a new way to track the effect of memory on brain structure. "With a specific MRI methodology called 'Diffusion Imaging MRI,' we can...

"Practice makes perfect" is the maxim drummed into students struggling to learn a new motor skill "” be it riding a bike or developing a killer backhand in tennis. Stunning new research now reveals that the brain can also achieve this motor memory with a prosthetic device, providing hope that physically disabled people can one day master control of artificial limbs with greater ease.In this study, to be published July 21 in the open-access journal PLoS Biology, macaque monkeys using...

"Practice makes perfect" is the maxim drummed into students struggling to learn a new motor skill "“ be it riding a bike or developing a killer backhand in tennis. In order to become proficient in any motor task, all that practice must eventually modify the performer's nervous system so that stable motor memories of the physical actions are formed. In this week's issue of PLoS Biology, new research reveals that macaque monkeys can achieve a kind of consolidation of motor memory when...

Why are some people smarter than others? In a new article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, Eduardo Mercado III from the University at Buffalo, The State University of New York, describes how certain aspects of brain structure and function help determine how easily we learn new things, and how learning capacity contributes to individual differences in intelligence. Cognitive plasticity is the capacity to learn and improve...

In an article published in the June 25th edition of the journal Neuron, researchers at the Hotchkiss Brain Institute, University of Calgary, have found that synaptic plasticity, long implicated as a device for 'change' in the brain, may also be essential for stability.Homeostasis, the body's own mechanism of regulating and maintaining internal balance in the body, is necessary for survival. Precisely how the brain pulls off this tricky balancing act has not been well appreciated.By examining...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
