AudioSpike is designed to set up electrophysiological multichannel measurements with acoustical stimulation with
high-performance real-time spike detection and evaluation on-the-fly. It uses standard sound cards on
Microsoft® Windows® for stimulation and spike recording: there is no need to use expensive proprietary
hardware for collecting the electrode signal.
Information on the technical requirements can be found in the Technology
The main features of AudioSpike include:
- multichannel spike detection (recording) with sample-accurate synchronization of all channels.
The number of channels is limited only by the number of souncard channels
- multichannel acoustical stimulation with sample-accurate synchronization of all channels
- real-time GUI interfaces:
- spiketrain plots with visual setting of threshold
- spike waveform plots
- cluster plots (X-Y plots of spike parameters) with spike selection for PSTH generation
- PSTH with selection features for parameter plots
- Parameter plots: X-Y bubble plots plotting the number of spikes within PSTH selection for
stimulus parameter combinations
- Period historgram and vector strength plots
- two search modes:
- free-search mode: select stimulus (frequency and level) while searching for cells. Spiketrains
and spikes are plotted live (with optional averaging mode).
- list search: load a stimulus list and play stimuli looped until a new one is selected
- easy-to-use calibration and frequency equalisation interfaces for level calibration
- additional equalisation mode for loading own frequency responses (impulse responses)
- in-situ calibration procedure
- interfaces from/to MATLAB®/Octave
- generate your measurement paradigms and your stimuli in MATLAB®/Octave and pass them to AudioSpike
- load measurement and evaluation data back to MATLAB®/Octave including raw spiketrain data, spike
waveforms and complete spike and stimulus parameter information for each spike
- monitor feature: 'listen' to electrode signals while searching.
- detailed documentation including examples and how-to's.
