Extracellular recordings from macaque hippocampus while navigating via a joystick a familiar and unfamiliar virtual maze projected in stereo, and binocular eye movements.

The dataset is made of 101 cells recorded in the hippocampus from two Rhesus macaques. Recordings were made extracellularly with either single tungsten electrodes or 16 contact u-probes. Activity was recorded as animals were navigating via a joystick a virtual maze projected in stereo, searching for a reward in two successive mazes: a familiar one and a daily new one. Both mazes contained five landmarks that could be used to find reward. Each file contains the timestamps of the action potentials, the X,Y position and camera orientation in virtual coordinates, the left and right eye X,Y coordinates, and task relevant event codes. For each file, two subfields correspond to the familiar maze (“famallo’), and the new maze (“newallo”). These fields contain the behavioral trial information for path entry and identity, choices made by the animal as described below. The dataset also contains the animal coordinates in the state space graph developed to analyze the neural data (Wirth et al., 2017). Each file corresponds to two recording session of approximatively 30 minutes each.
