    Artificial neural networks are known to perform well on recently learned tasks, at the same time forgetting previously learned ones. The authors propose an unsupervised sleep replay algorithm to recover old tasks synaptic connectivity that may have been damaged after new task training.

    Classical forgetting methods typically re-expose people to reminders of their unwanted memories. Here, the authors disrupt unpleasant memories by subliminally reactivating them as participants suppress retrieval of unrelated neutral memories, avoiding the need for conscious exposure.

    It remains unclear how past experiences shape how new information is acquired and represented in the brain. Here, the authors provide data suggesting that past experiences influence neocortical integration and the organization of new overlapping memories across time.

    The authors used intracranial EEG recordings from patients with epilepsy to show that successful intentional forgetting is due to a selective modification of item-specific top-down connections and not simply a degradation of the memory traces.

    Impairments in memory flexibility are associated with neuropsychiatric disorders such as PTSD and autism. Here, the authors report that the transcriptional repressor Wilm's Tumor 1 regulates synaptic plasticity leading to weakening of memory strength and enabling memory flexibility.

    Emotional memory can change when retrieved, yet the conditions under which this can occur are not fully described. Here, authors show that taking a pill of propranolol taken during a specific time window can change the expression of fear memory in a person, and that sleep is necessary to forget learned fear.

    New neurons are continuously produced throughout adulthood in the hippocampus. Here the authors provide evidence that adult hippocampal neurogenesis weakens existing memories, and facilitates the encoding of new, confliction information in mice.

    Rapidly switching the focus of attention is believed to impair memory, but it is unclear how. Lewis-Peacock and Norman use brain imaging and multivariate analysis to show that when two memories briefly and closely compete in the brain, there is a lasting impairment in the ability to remember these thoughts.
