Cherckerboard reversal

Hi,

 

I am a neurologist starting to use Psychtoolbox…(better to study “how to”   )

 

First thing I intend to do is just create a Checkerboard reversal pattern on the screen. It can give a trigger or be triggered using usb 1208FS device when the pattern reversal happens….

This must be a very basic thing for experienced users… for me it is far from evident… so who can help me to find it out.

 

I am also starting to get some Matlab programming knowledge. In what I call as my…. “brainjogging program”  (as a 55 years old clinical oriented neurologist…)

 

Sincerely,

 

 

Patrick De Wit
