Data used in the manuscript "Distributed coding of duration in rodent prefrontal cortex during time reproduction" Henke et al ... (add full citation including doi).

Extracellular recordings from neurons in gerbil (Meriones unguiculatus) medial prefrontal cortex. Data was acquired with chronically implanted tetrodes from three animals.

Overview of contents

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. A data file comprises

• spike train of the neuron, i.e. array with spike times across the whole session
• measurement phase: time points of stimulus onset and the stimulus duration (stimulus onsets and stimuli)
• reproduction phase: time points of reproduction onset and the reproduced duration (reproduction onsets and reproductions)
• reward information for each trial, i.e. rewards, 0 - no reward, 1 - reward
  
  

File names are composed of animalID_sessionNumber_tetrodeNumber_neuronNumber.nix.

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

Basic usage

Since nix uses HDF5 as a backend, you may have a first look at the data with a HDF viewer.

Basic code to load one of the nix file and plot the data contained is provided in ... .py
