Neural correlates of the LSD experience revealed by multimodal neuroimaging

Neural correlates of the LSD experience revealed by multimodal neuroimaging

Lysergic acid diethylamide (LSD) is the prototypical psychedelic drug, but its effects on the human brain have never been studied before with modern neuroimaging. Here, three complementary neuroimag-ing techniques: arterial spin labeling (ASL), blood oxygen level- dependent (BOLD) measures, and magnetoencephalography (MEG), implemented during resting state conditions, revealed marked changes in brain activity after LSD … Read more

Spatial Dependencies between Large-Scale Brain Networks

Spatial Dependencies between Large-Scale Brain Networks

Spatial Dependencies between Large-Scale Brain Networks Functional neuroimaging reveals both increases (task-positive) and decreases (task-negative) in neural activation with many tasks. Many studies show a temporal relationship between task positive and task negative networks that is important for efficient cognitive functioning. Here we provide evidence for a spatial relationship between task positive and negative networks. … Read more
