LSD's impact on human brain imaged for 1st time
In a first, scientists in the UK have imaged the impact of LSD (lysergic acid diethylamide) on the human brain. LSD, also known as acid, is a psychedelic drug known for its psychological effects. "We saw many more areas of the brain than normal were contributing to visual processing under LSD, even though volunteers' eyes were closed",  a researcher said.
