New knowledge about the human brain's plasticity

The brain's plasticity and its adaptability to new situations do not function the way researchers previously thought, according to a new study published in the journal Cell. Earlier theories are based on laboratory animals, but now researchers at Karolinska Institutet in Sweden have studied the human brain.

Ghost illusion created in the lab

Ghosts exist only in the mind, and scientists know just where to find them, an EPFL study suggests. Patients suffering from neurological or psychiatric conditions have often reported feeling a strange "presence". Now, EPFL researchers in Switzerland have succeeded in recreating this so-called ghost illusion in the laboratory.

Images of a nearly invisible mouse

Researchers at the RIKEN Quantitative Biology Center in Japan, together with collaborators from the University of Tokyo, have developed a method that combines tissue decolorization and light-sheet fluorescent microscopy to take extremely detailed images of the interior of individual organs and even entire organisms. The work, published in Cell, opens new possibilities for understanding the way life works--the ultimate dream of systems biology--by allowing scientists to make tissues and whole organisms transparent and then image them at extremely precise, single-cell resolution.

Human stem cell-derived neuron transplants reduce seizures in mice

Belmont, MA--McLean Hospital and Harvard Stem Cell Institute scientists have new evidence that stem cell transplantation could be a worthwhile strategy to help epileptics who do not respond to anti-seizure drugs.

Direct generation of neural stem cells could enable transplantation therapy

CAMBRIDGE, Mass. (November 6, 2014) - Induced neural stem cells (iNSCs) created from adult cells hold promise for therapeutic transplantation, but their potential in this capacity has been limited by failed efforts to maintain such cells in the desirable multi-potent NSC state without continuous expression of the transcription factors used initially to reprogram them.

U-M researchers provide first peek at how neurons multitask

ANN ARBOR--Researchers at the University of Michigan have shown how a single neuron can perform multiple functions in a model organism, illuminating for the first time this fundamental biological mechanism and shedding light on the human brain.

Failed Alzheimer's test shows in which direction the research should continue

Disappointing results in clinical Alzheimer's studies discourage doctors and scientists from continuing their research into ɣ-secretases and a possible treatment against Alzheimer's disease. In the prestigious journal Cell, the Alzheimer's expert Bart De Strooper (VIB-KU Leuven) argues that these studies are not pointless, but merely indicate what the next steps should be for the Alzheimer's research. This article - or rather, this message - will be spread at the largest Neuroscience meeting that will take place mid-November in Washington.

Retaining military veteran employees is all about the right fit

It's a difficult career transition that can lead to more professional frustration and shorter tenure on the job for many of the newest generation of veterans employed with the U.S. Department of Veterans Affairs (VA) compared to their non-veteran co-workers.

New research from the University of Cincinnati is helping VA analyze the process of reintegrating veterans into civilian careers and evaluate methods for easing that transition. That's good news for all veterans as the nation prepares to observe Veterans Day on Nov. 11.

Black, Hispanic kids underrepresented in autism identification

LAWRENCE -- The number of children diagnosed with autism has increased in recent years, but a new study co-authored by a University of Kansas professor shows that while the number of students with autism increased in every state from 2000 to 2007, black and Hispanic children were significantly underrepresented.

Joslin scientists discover new step in a molecular pathway responsible for birth defects

BOSTON - (November 6, 2014) - Mary R. Loeken, Ph.D., Investigator in the Section on Islet Cell and Regenerative Biology at Joslin Diabetes Center and Associate Professor of Medicine at Harvard Medical School, has discovered a molecular pathway responsible for neural tube defects in diabetic pregnancies. Her latest research findings in this pathway were published in the October issue of Diabetes.

Having a Y chromosome doesn't affect women's response to sexual images, brain study shows

Women born with a rare condition that gives them a Y chromosome don't only look like women physically, they also have the same brain responses to visual sexual stimuli, a new study shows.

The journal Hormones and Behavior published the results of the first brain imaging study of women with complete androgen insensitivity, or CAIS, led by psychologists at Emory.

Piglet brain atlas new tool in understanding human infant brain development

URBANA, Ill. – A new online tool developed by researchers at the University of Illinois will further aid studies into postnatal brain growth in human infants based on the similarities seen in the development of the piglet brain, said Rod Johnson, a U of I professor of animal sciences.

For leaders, looking intelligent is less important than looking healthy

People look for candidates with a healthy complexion when choosing a leader, but don't favor the most intelligent-looking candidates except for positions that require negotiation between groups or exploration of new markets. These results are published in the open-access journal Frontiers in Human Neuroscience.

Brian Spisak from the VU University Amsterdam and colleagues studied people's implicit preferences for traits of leaders, such as health, intelligence, and attractiveness, and how they look for information about these qualities in the physical appearance of others.

The female nose always knows: Do women have more olfactory neurons?

Rio de Janeiro, Brazil -Individuals show great diversity in their ability to identify scents and odors. More importantly, males and females greatly differ in their perceptual evaluation of odors, with women outperforming men on many kinds of smell tests.

Sex differences in olfactory detection may play a role in differentiated social behaviors and may be connected to one's perception of smell, which is naturally linked to associated experiences and emotions. Thus, women's olfactory superiority has been suggested to be cognitive or emotional, rather than perceptual.

UW study shows direct brain interface between humans

Sometimes, words just complicate things. What if our brains could communicate directly with each other, bypassing the need for language?
