Neurons involved in working memory fire in bursts, not continuously

How we are able to keep several things simultaneously in working memory
March 21, 2016

Pictured is an artist’s interpretation of neurons firing in sporadic, coordinated bursts. “By having these different bursts coming at different moments in time, you can keep different items in memory separate from one another,” Earl Miller says. (credit: Jose-Luis Olivares/MIT)

We need to forget things to make space to learn new things, scientists discover

Mice study, if confirmed in people, might help forget traumatic experiences

Magnetic microscope image of three nanomagnetic computer bits. Each bit is a tiny bar magnet only 90 nanometers long. The microscope shows a bright spot at the "North" end and a dark spot at the "South" end of the magnet. The "H" arrow shows the direction of magnetic field applied to switch the direction of the magnets. (credit: Image by Jeongmin Hong and Jeffrey Bokor)

New synthesized molecule could reduce brain damage in stroke victims

March 14, 2016

This graphic depicts a new inhibitor, 6S, locking up an enzyme (red) to block the production of hydrogen sulfide (yellow and white). Hydrogen sulfide concentrations have been shown to climb after the onset of a stroke, leaving to brain damage. (credit: Matthew Beio, University of Nebraska-Lincoln)
