Definition

Navigation is the process by which an animal or individual establishes its present location and plans a route to a future destination within its environment.

    Spatial navigation and memory depend on neural coding of an organism’s location as well as large-scale knowledge of the environment, but how animals organize information in task-relevant spatial segments is not well understood. Here the authors show that, in rats, perirhinal neurons perform integrative operations, globally specifying where, in the task context, an animal is located.

    The authors investigate the role of inhibition in shaping spatial selectivity of CA1 place cells. Combining whole-cell recordings, optogenetics and computational modeling, they demonstrate that inhibition enhances both rate and temporal coding of space by counteracting noise from broad out-of-field excitation.

    Using an environment composed of interconnected paths, the authors demonstrate that subiculum encodes a previously unrecognized form of spatial information, the axis of travel. This discovery has implications for how path positions and orientations can be related to the larger environment.

    The authors describe a glutamatergic septoentorhinal pathway that provides running-speed-correlated input to MEC layer 2/3. The speed signal is integrated by several MEC cell classes and converted into speed-dependent output. This speed circuit may be important for the spatial computations of MEC neurons.
