This is an historical archive of the activities of the MRC Anatomical Neuropharmacology Unit (MRC ANU) that operated at the University of Oxford from 1985 until March 2015. The MRC ANU established a reputation for world-leading research on the brain, for training new generations of scientists, and for engaging the general public in neuroscience. The successes of the MRC ANU are now built upon at the MRC Brain Network Dynamics Unit at the University of Oxford.

News- Play it again: reactivation of waking experience and memory

In the May issue of Trends in Neurosciences, on pages 220-229, authors O'Neill et al. highlight emerging evidence suggesting that sharp wave/ripple events in the hippocampus coordinate the reactivation of memory traces. The cover image depicts a representationof reactivation during sleep. The background image shows a closed eye with traces of sleep-associated local fieldpotentials, to represent sleep. The place fields of four cells are illustrated, of which the blue and red cells show overlappingfields. During sleep these waking patterns are reactivated, through the joint firing of the blue and red cells. This reactivationis depicted in the foreground, by the joint firing of the red and blue pyramidal cells. Cover credit: Ben Micklem
