A new study of human intelligence by University of Warwick researchers and associates at nine universities in China and NEC Laboratories America has quantified the brain’s dynamic functions, identifying how different parts of the brain interact with each other at different times, they reported in the journal Brain.

The more variable a brain is, and the more its different parts frequently connect with each other, the higher a… read more

UNC Health Care | UNC Science Short: Sleep Spindles

University of North Carolina (UNC) School of Medicine scientists report using transcranial alternating current stimulation (tACS) to enhance memory during sleep, laying the groundwork for a new treatment paradigm for neurological and psychiatric disorders.

The findings, published in the journal Current Biology, offer a non-invasive method to potentially help millions of people with conditions such as autism, Alzheimer’s… read more

MIT researchers have developed a new technique for imaging brain tissue at multiple scales, allowing them to peer at molecules within cells or take a wider view of the long-range connections between neurons.

This technique, known as “magnified analysis of proteome” (MAP), should help scientists in their ongoing efforts to chart the connectivity and functions of neurons in the human brain, says Kwanghun Chung, the… read more

Kalipada Pahan, PhD, a researcher at Rush University and the Jesse Brown VA Medical Center in Chicago, has found that cinnamon improved performance of mice in a maze test.

His group published their latest findings online June 24, 2016, in the Journal of Neuroimmune Pharmacology.

“The increase in learning in poor-learning mice after cinnamon treatment was significant,” says Pahan. “For example, poor-learning mice took… read more

How many of the estimated 100 trillion synapses in your brain are actually functioning? It’s an important question for diagnosis and treatment of people with common brain disorders, such as epilepsy, Alzheimer’s disease, autism, depression, schizophrenia, and traumatic brain injury (TBI), but one that could not be answered, except in an autopsy (or an invasive surgical sample of a small area).

Now a Yale-led team of researchers… read more

Using neuroimaging data, Carnegie Mellon University researchers have identified four distinct stages of math problem solving, according to a new study published in the journal Psychological Science.

“How students were solving these kinds of problems was a total mystery to us until we applied these techniques,” says psychological scientist John Anderson, lead researcher on the study. “Now, when students are sitting there thinking hard, we can tell… read more

Cognitive brain training improves executive function while aerobic activity improves memory, according to a new study by the Center for BrainHealth at The University of Texas at Dallas.

The study, published in an open-access paper in Frontiers in Human Neuroscience, compared cerebral blood flow and cerebrovascular reactivity data, obtained via MRI, for two groups of healthy sedentary adults ages 56–75 years. The members of both… read more
