-**ShowPlay Reference Manual, Chapter 1 (Introduction): Physio**
-===== Recording physiological signals in real-time=====
-ShowPlay is designed to automatically record a variety of behavioral variables during any real-time paradigm.  Behavioral recording is controlled by a few standard control variables. For recording physiological signals such as heart-beat or repiration you must have appropriate physiological transducer hardware installed and connected to your computer. Once enabled, physiological signals are recorded throughout every ShowPlay paradigm without any modification to the paradigm itself.
-Recording physiological signals involves 3 steps:
-  * 1 - configuring the computer hardware used for reading the signals
-  * 2 - setting the software control variables to indicate which channels to record
-  * 3 - connecting the physiological transducers to the subject and verifying their signals
-**Step 1 - Configuring the computer hardware**\\
-Using CIGAL's **Settings** menu, select: **Configuration Settings**
-I recommend turning on the SRBox as device 2 (set order=2) to enable the scanner to trigger your tasks.
-Physiological signals (cardiac, respiration, GSR) are analog voltages converted to digital values by the Measurement Computing Analog/Digital converter box.  You must therefore configure CIGAL to initialize the MeasComp box (e.g. set order=3 for meascomp).
-If you want to record eye-position as well you can turn on the eyetracker (order=4).
-On BIAC6, the **userconfig.imp** file I typically use has these lines:
-  srbox 1 - 5
-  meascomp 0 8 - - - - - - 2
-  eyetracker 3
-**Step 2 - Setting the software control variables**\\
-Using CIGAL's **Settings** menu, select: **Hardware Settings**
-Turn on the data channels you want to record. These are typically **digio**, **keybd/mouse**, **cardiac**, **respiration**, and **eye-position**.  The channel numbers should be correct by default.
-To record efficiently on the MeasComp box, click the **analog scan sampling** box **On**.
-**Step 3 - Verifying physiological transducer signals**\\
-Using CIGAL's **Display** menu, select: **Show Behavior** and then choose **Real-time values**.
