Crayfish Brain May Offer Rare Insight into Human Decision Making
University of Maryland, College Park

Crayfish make surprisingly complex, cost-benefit choices, finds a University of Maryland study -opening up a new line of research to help unravel the cellular brain activity involved in human decisions. It concludes crayfish are a practical way to identify the neural circuitry and chemistry of decision making. No direct way exists to do this in primates.

Crocodile and Hippopotamus Served as “Brain Food” for Early Human Ancestors
 Johns Hopkins University

Fish really is “brain food.” And it seems that even pre-humans living as far back as 2 million years ago somehow knew it.

‘Sound’ Science Offers Platform for Brain Treatment and Manipulation
Arizona State University College of Liberal Arts and Sciences

The ability to diagnose and treat brain dysfunction without surgery may rely on a new method of noninvasive brain stimulation using pulsed ultrasound developed by a team of scientists led by William “Jamie” Tyler, a neuroscientist at Arizona State University.

Researchers Discover a Cause of Cognitive Decline in Aging Population
Mount Sinai Health System

Researchers at Mount Sinai School of Medicine have found that certain types of specializations on nerve cells called “spines” are depleted as a person ages, causing cognitive decline in the part of the brain that mediates the highest levels of learning.

More than Half of Liver Patients Have Neurocognitive Impairments
Loyola Medicine

Fifty-four percent of liver patients also display neurocognitive impairments such as short term memory loss, a study found. Average score of impaired patients was lower than that of patients with early-stage Alzheimer's disease.

Biomarkers Weigh In at Mild Cognitive Impairment Meeting
Alzforum

Forget sun, sand, and surf—it was biomarker pools and a sea change in neurocognitive testing that rejuvenated attendees at the 8th Annual Symposium on Early Alzheimer's, held 12-13 March 2010, in Miami Beach, Florida. Our intrepid reporter Pat McCaffrey brings you a full meeting summary, complete with a slide deck that covers the majority of presentations.
