PsPM-SCRV_10 dataset
====================

Repository Version: 2017.02.14

This dataset includes skin conductance response (SCR) measurements recorded from 3 locations (see section 'Data files' below) for each of 26 healthy unmedicated participants (12 males and 14 females aged 24.4+/-4.9 years) in response to an auditory stimulus (single white noise bursts, 1s length; 10ms ramp; ~85dB). Participants are asked to press a foot pedal upon hearing a stimulus.

Data Files:
- Files holding biosignal traces, recorded with CED spike software.
   - event markers used for synchronization with Cogent files, marker are set at sound presentation onset (channel 1)
   - skin conductance on the thenar/hypothenar of the non-dominant hand (channel 2)
   - skin conductance on the volar middle phalanx of the dominant 2nd/3rd finger (channel 3)
   - skin conductance on the medial plantar surface of the non-dominant foot (channel 4)
   - heart beat time stamps(channel 5), never checked for integrity.
   - respiration (channel 6), never checked for integrity.
- Files holding keyboard presses, recorded with Cogent 2000 software.

The data file name is composed of: 
 - SCRV_10       The dataset name
 - spike/cogent The type of data recorded (see above)
 - XX           The subject number

Data are stored as .mat files for use with MATLAB (The MathWorks Inc., Natick, USA) in a format readable by the PsPM toolbox (pspm.sourceforge.net). All matlab files are saved in MATLAB 8.6 (R2015b) format.
