Salk Institute Salk scientists show that the little-known supportive cells are vital in cognitive function When you're expecting something—like the meal you've ordered at a restaurant—or when something captures your interest, unique electrical rhythms sweep through your brain. These waves are called gamma oscillations and they reflect a symphony of cells—both excitatory and inhibitory—playing together in an orchestrated way. Though their role has been debated, gamma waves...

redOrbit Staff & Wire Reports - Your Universe Online In research that should provide a more detailed picture of how memory works, scientists from the Salk Institute have developed a new model explaining how neurons retain select memories a few hours after an event. “Previous models of memory were based on fast activity patterns,” study author and Howard Hughes Medical Institute Investigator Terry Sejnowski explained in a statement on Wednesday. “Our new model of memory makes...

Brain Epigenome Changes Through Developmental Years

Brett Smith for redOrbit.com - Your Universe Online While the entire genome has been sequenced and the codes of many genes have been identified, there are is a wide range of unknown mechanisms that interact with the code without changing "letters" of the DNA. These chemical changes to DNA are referred to as the epigenome, and a new study in the journal Science has revealed significant epigenomic activity during brain development. DNA includes four chemical bases: adenine (A), guanine...

There is strength in numbers if you want to get your voice heard. But how to do you get your say if you are in the minority? That's a dilemma faced not only by the citizens of a democracy but also by some neurons in the brain. Although they only account for a fraction of the synapses in the visual cortex, neurons in the thalamus get their message across loud and clear by coordination -- simultaneously hitting the "send" button"”according to a computer simulation developed by researchers...

Of all the qualities that distinguish humans from other species, how we learn is one of the most significant. In the July 17, 2009 issue of the journal Science, researchers who are at the forefront of neuroscience, psychology, education, and machine learning have synthesized a new science of learning that is already reshaping how we think about learning and creating opportunities to re-imagine the classroom for the 21st century. "To understand how children learn and improve our educational...

Researchers have constructed a new detailed map of the three-dimensional terrain of a synapse -- the junction between neurons which are critical for communication in the brain and nervous system. The "nano-map," which shows the tiny spines and valleys resolved at nanometer scale, or one-billionth of a meter, has already proven its worth in changing scientists' views of the synaptic landscape. Using the map as a guide, the research team, led by Howard Hughes Medical Institute investigator...
