(Medical Xpress)—A new study conducted by monitoring the brain waves of sleeping adolescents has found that remarkable changes occur in the brain as it prunes away neuronal connections and makes the major transition from childhood to adulthood. http://medicalxpress.com/news/2013-03-reveals-adolescent-brain-transition-mature.html Neuroscience Tue, 19 Mar 2013 09:51:26 EST news282905473 Neuroscientists from Wayne State University and the Massachusetts Institute of Technology (MIT) are taking a deeper look into how the brain mechanisms for memory retrieval differ between adults and children. While the memory systems are the same in many ways, the researchers have learned that crucial functions with relevance to learning and education differ. The team's findings were published on July 17, 2012, in the Journal of Neuroscience. http://medicalxpress.com/news/2012-07-team-memory-children-adults.html Neuroscience Tue, 24 Jul 2012 12:43:23 EST news262352594 (HealthDay) -- Adolescents born with extremely low birth weight (ELBW) in the 1990s assess their current health and well-being similarly to teens born at normal birth weight but report less risk taking, according to a study published online June 4 in Pediatrics. http://medicalxpress.com/news/2012-06-low-birth-weight-teens-health-similar-peers.html Pediatrics Mon, 04 Jun 2012 18:20:01 EST news258050440 Over the first few years of life, human cognition continues to develop, soaking up information and experiences from the environment and far surpassing the abilities of even our nearest primate relatives. In a study published online today in Genome Research, researchers have identified extended synaptic development in the human brain relative to other primates, a finding that sheds new light on the biology and evolution of human cognition. http://medicalxpress.com/news/2012-02-synaptic-cognitive-edge-primates.html Genetics Wed, 01 Feb 2012 17:00:08 EST news247337372 Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study, published by Cell Press in the December 8 issue of the journal Neuron, reveals that functionally connected brain regions mature together and uncovers fascinating sex-specific differences in brain development. http://medicalxpress.com/news/2011-12-big-picture-long-term-imaging-reveals.html Neuroscience Wed, 07 Dec 2011 12:25:30 EST news242483118 During childhood and adolescence, children develop the ability to remember not only past events but the origin of those memories. For example, someone may remember meeting a particular person and the context in which he or she met that person. New research from Germany has found that the ability to remember the origin of memories is a relatively long process that matures during adolescence but isn't fully developed until adulthood. http://medicalxpress.com/news/2011-08-ability-memories-fully-youths.html Psychology & Psychiatry Tue, 30 Aug 2011 03:47:49 EST news233894854 Researchers in Australia have discovered that mothers who smoke during pregnancy are causing developmental changes to their unborn babies that lead to them having lower levels of the type of cholesterol that is known to protect against heart disease in later life – high-density lipoprotein (HDL) cholesterol. http://medicalxpress.com/news/2011-06-pregnancy-lowers-good-hdl-cholesterol.html Cardiology Wed, 22 Jun 2011 03:31:03 EST news227932238 Teens are rarely described as stable, so when something about their rapidly changing brains remains placidly unaltered, neuroscientists take notice. Such is the case in a new study of electroencephalography (EEG) readings gathered from dozens of teens while they slept. Despite the major neural overhaul underway during adolescence, most individuals maintained a unique and consistent pattern of underlying brain oscillations. The work lends a new level of support to the idea, already observed in adults, that people produce a kind of brainwave "fingerprint." http://medicalxpress.com/news/2011-04-teen-evidence-neural-fingerprint.html Neuroscience Tue, 26 Apr 2011 17:37:04 EST news223058201
