===== Recording physiological signals in real-time===== | ===== Recording physiological signals in real-time===== | ||
+ | |||
+ | ShowPlay is designed to automatically record a variety of behavioral variables during any real-time paradigm. | ||
+ | |||
+ | 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**\\ | ||
+ | At the BIAC scanners, the default **sysconfig.imp** file automatically initializes: | ||
+ | * graphics - the display screen, keyboard, mouse, and most USB response boxes | ||
+ | * srbox - the EPrime Stimulus/ | ||
+ | * meascomp - the Measurement Computing analog/ | ||
+ | * eyetracker - connection to 2nd computer to read Viewpoint eyetracking signals\\ | ||
+ | If those are all the devices you need you do not need to change the configuration. | ||
+ | |||
+ | If you do want to use different hardware devices, use CIGAL' | ||
+ | |||
+ | To change devices, select: | ||
+ | To turn on or off a device, set the initialization Order value (first col). Set to 0 to not use.\\ | ||
+ | Each device will have several parameter options, which should default to optimal values. | ||
+ | | ||
+ | **Step 2 - Setting the software control variables**\\ | ||
+ | Using CIGAL' | ||
+ | |||
+ | Turn on the data channels you want to record. These are typically **digio**, **keybd/ | ||

+ | To record efficiently on the MeasComp box, click the **analog scan sampling** box **On**. | ||
