  • Here the authors compare place cell sequence coding during correct and error trials in a spatial memory task. Sequences coded paths that were longer and more temporally compressed during correct trials and developed a bias to replay paths to a goal location during rest periods of correct but not error trials.

  • Certain neurons encode memories of events that occurred in specific physical locations known as place fields. Chickadees show patterns of neuronal activity that are specific to locations of hidden food but independent of place fields.

  • Grid cells confer a spatial impression of an animal's environment on the brain. Their firing patterns in a cave-dwelling bat reopen old questions about how they do this, and pose some compelling new ones. See Letter p.103

  • Local field potential recordings of the hippocampus reveal three types of neural activity rhythms: theta, sharp wave–ripples and gamma. In this Review, Colgin discusses recent findings from rodent studies that provide insight into the origin of these rhythms and their roles in memory and other behaviours.

  • Gamma oscillations in the brain are thought to 'bind' spatially distributed cells, a function that is probably important in perception, attentional selection and memory. However, it is unclear why the frequency of gamma oscillations varies substantially across space and time. Here, the study of the frequency of gamma oscillations in the CA1 area of the hippocampus suggests that variations in gamma frequency may be important for routeing information in the brain.

  • Hippocampal place cells are traditionally thought to represent locations where animals currently are or predict where they are headed. However, new results reveal that place cells also represent distant places that are actively avoided.

  • The firing of most hippocampal neurons is modulated by the theta rhythm, but it's not clear how and where the rhythm is generated. A study now shows that the required machinery for theta generation lies in local circuits of the hippocampus.
