A national team of researchers led by investigators at the University of California, San Diego School of Medicine have developed a multidimensional set of brain measurements that, when taken together, can accurately assess a child’s age with 92 percent accuracy. “We have uncovered a ‘developmental clock’ within the brain — a biological signature of maturation […]

The Roadmap To Alzheimer’s Disease Begins – Initial Findings Indicate That Varying Brain Activity May Reduce The Risk
Activity lingers longer in certain areas of the brain in those with Alzheimer’s disease than it does in healthy people, Mayo Clinic researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer’s disease. Included in this report is a video summary of the study […]
Researchers Uncover Two Brain Signals Involved In How Humans Predict Other Peoples’ Decisions
Researchers at the RIKEN Brain Science Institute (BSI) in Japan have uncovered two brain signals in the human prefrontal cortex involved in how humans predict the decisions of other people. Their results suggest that the two signals, each located in distinct prefrontal circuits, strike a balance between expected and observed rewards and choices, which enables […]
Brain Structure Helps Guide Behavior By Anticipating Changing Demands
Every day the human brain is presented with tasks ranging from the trivial to the complex. How much mental effort and attention are devoted to each task is usually determined in a split second and without conscious awareness. Now a study from Massachusetts General Hospital (MGH) researchers finds that a structure deep within the brain, […]
FMRI Images Show How The Brain Looks When Out Of Patience And Losing Self-Control
New pictures from the University of Iowa show what it looks like when a person runs out of patience and loses self-control. A study by University of Iowa neuroscientist and neuro-marketing expert William Hedgcock confirms previous studies that show self-control is a finite commodity that is depleted by use. Once the pool has dried up, […]
Schizophrenia Diagnosis (But Not Bipolar Diagnosis) Associated With Progressive Brain Changes Among Adolescents
Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. The research was carried […]
Brain Imaging Study Evaluates Effects Of Marijuana Ingredients On Brain Functioning
Different ingredients in marijuana appear to affect regions of the brain differently during brain processing functions involving responses to certain visual stimuli and tasks, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. Sagnik Bhattacharyya, M.B.B.S., M.D., Ph.D, at the Institute of Psychiatry, King’s College in […]
Maltreated Children Show Same Pattern Of Brain Activity As Combat Soldiers
Children exposed to family violence show the same pattern of activity in their brains as soldiers exposed to combat, new research has shown. In the first functional MRI brain scan study to investigate the impact of physical abuse and domestic violence on children, scientists at UCL in collaboration with the Anna Freud Centre, found that […]
