Using a mouse model of autism.

Using a mouse model of autism, researchers from the University of Chicago recognized a malfunctioning neural circuit connected with reduced capacity for motor learning. This appears to occur from an inability to get rid of unneeded neural connections in the brain. They report their results Nov. 24 in Nature Communications. ‘We’ve identified synaptic abnormalities that may are likely involved in motor complications typically seen in kids with autism,’ said study senior author Christian Hansel, PhD, professor of neurobiology at the University of Chicago.An accompanying editorial by Dr. David Goldman, chief of the Laboratory of Neurogenetics at the U.S. National Institute of Alcohol Misuse and Alcoholism, said these results show that marijuana isn’t a harmless drug. ‘The responsibility of cannabis’ effects may fall more heavily on people who, due to genetic makeup or early life exposures, are in very best risk for brain structural changes, psychosis or addiction,’ Goldman wrote. ‘It really is safer never to expose people to psychoactive drugs.’ But Paul Armentano, deputy director of NORML, a combined group promoting marijuana legalization, said the scholarly research indicate that pot is forget about dangerous than additional legal substances.
