With thorns you can analyze and display spike trains generated by neurons. It can be useful for the analysis of experimental and simulation data using Python. For example, you can easily calculate peristimulus time histogram (PSTH), interspike time histogram (ISIH), vector strength (VS), entrainment and visualize action potentials with raster plot.
waves is a submodule with some useful signal processing and generation functions, e.g. generate ramped tone, amplitude modulation tone, FFT filter, set level (dB_SPL).
The software was originally developed during my PhD in the group of Werner Hemmert at the TUM. It is oriented towards auditory research, but it could be easily extended.
Initialize and load spike trains:
import thorns as th from thorns.datasets import load_anf_zilany2014 spike_trains = load_anf_zilany2014()
Calculate vector strength:
Generate and plot AM tone:
import thorns.waves as wv sound = wv.amplitude_modulated_tone( fs=48e3, fm=100, fc=1e3, m=0.7, duration=0.1, ) wv.plot_signal(sound, fs=48e3) wv.show()

- Analyzes and displays spike trains
- Uses pandas.DataFrame as the main data container (spike trains, results)
- Handy signal processing and generating functions: thorns.waves
- Map implementation with various backend (also parallel) and caching: thorns.util.map()
- Dumpdb: quickly dump map()’s results in one script and load from another one: thorns.util.dumpdb(), thorns.util.loaddb()
- Pure Python
In order to use thorns, you’ll need to install the following dependencies first:
- Python (2.7)
- PyTables / tables
- py-notify (optional, enables notifications)
Next, type in your command line:
pip install thorns
