Data used in the manuscript "Distributed coding of duration in rodent prefrontal cortex during time reproduction" Henke et al. eLife.
Extracellular recordings from neurons in gerbil (Meriones unguiculatus) medial prefrontal cortex. Data was acquired with chronically implanted tetrodes from three animals.
Each folder contains the data of one of the three gerbils used in the study. Each file in the folders contains data of a single neuron recorded in one recording session. File names are composed of animalID_sessionNumber_tetrodeNumber_neuronNumber.nix.
A data file comprises
In some trials technical problems occurred, e.g., the treadmill stuck. These were left out of in the arrays comprising trial information like time points. The spike times and distance covered still include these parts, since they are continuous signals that extend throughout the whole session.
Data is saved in nix format, which uses HDF5 as a backend, see
Stoewer A, Kellner CJ, Benda J, Wachtler T and Grewe J (2014). File format and library for neuroscience data and metadata. Front. Neuroinform. Conference Abstract: Neuroinformatics 2014. https://doi.org/10.3389/conf.fninf.2014.18.00027
Nix uses HDF5 as a backend and you may have a first look at the data with an HDF viewer.
Basic code to load one of the nix files and plot the data contained is provided
in load_data.py. The script takes the name of the file to load as a command
line parameter. Run the script from IPython with
%run load_data <folder/file_name.nix>
.
load_data.py was written and tested for Python 3 (3.8) and NIXPY 1.5.2.
