If a picture of a cat does not appear below in a short time, you need to install the free "Shockwave" plug-in from www.macromedia.com
Place your mouse cursor on the blank screen in front of the cat to present a line stimulus. Move the mouse to change the stimulus location, click it to change its orientation.
Click on the brain to advance the microelectrode. Click on the back of the electrode to withdraw it. Click on the round black electrode mount to change the path of the electrode from perpendicular to oblique.
