Rig Specs

Experiment Rig: G4 LED - Ephys arena with a cartoon representation of the position of the fly within the arena. For many protocols, visual stimuli are only presented over 1/2 of the arena screen, ipsilateral to the location of the recorded cell.

Important

Leftmost panel is not used, so there are 11 panels in total. When making patterns, the image will start being presented from pixel 17. Pixels 1-16 represent the missing panel.

Note

The arena can be tilted in elevation depending on how the fly is positioned in the rig. Make sure to keep a note of the angle of the arena.
