Brain-mapping projects to join forces

Brain-mapping projects to join forces | Neuroscience in The News | Scoop.it

US and European research programmes will begin coordinating research.

 

It seems a natural pairing, almost like the hemispheres of a human brain: two controversial and ambitious projects that seek to decipher the body's control center are poised to join forces.

The European Union’s €1-billion (US$1.3-billion) Human Brain Project (HBP) and the United States’ $1-billion Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative will launch a collaboration later this year, according to government officials involved in both projects.(...) - by Sara Reardon, Nature, 18 March 2014

Power failure: why small sample size undermines the reliability of neuroscience

A study with low statistical power has a reduced chance of detecting a true effect, but it is less well appreciated that low power also reduces the likelihood that a statistically significant result reflects a true effect. Here, we show that the average statistical power of studies in the neurosciences is very low. The consequences of this include overestimates of effect size and low reproducibility of results. There are also ethical dimensions to this problem, as unreliable research is inefficient and wasteful. Improving reproducibility in neuroscience is a key priority and requires attention to well-established but often ignored methodological principles. - By Button KS et al., Nature Reviews Neuroscience 14, 365-376 (May 2013)

Biomarkers could predict Alzheimer's before it starts

Study identifies potential blood test for cognitive decline.

A simple blood test has the potential to predict whether a healthy person will develop symptoms of dementia within two or three years. If larger studies uphold the results, the test could fill a major gap in strategies to combat brain degeneration, which is thought to show symptoms only at a stage when it too late to treat effectively.

See-through brains clarify connections

Technique to make tissue transparent offers three-dimensional view of neural networks.


A chemical treatment that turns whole organs transparent offers a big boost to the field of ‘connectomics’ — the push to map the brain’s fiendishly complicated wiring. Scientists could use the technique to view large networks of neurons with unprecedented ease and accuracy. The technology also opens up new research avenues for old brains that were saved from patients and healthy donors. (...) - by Helen Shen, Nature News, 10 April 2013
