Synchronous neural activity is related with memory encoding and retrieval, but it is not clear whether this happens across the whole brain. Here, authors use intracranial recordings to show that gamma networks are largely asynchronous, desynchronizing while theta synchronizes during memory encoding and retrieval.
The recently updated US National Institutes of Health clinical trials policies will apply broadly to studies involving experimental manipulations of humans. These studies will require registration and reporting in ClinicalTrials.gov, grant application submission under a clinical trials funding opportunity announcement, and Good Clinical Practice training for investigators.
