A flexible geometry for panoramic visual and optogenetic stimulation during behavior and physiology.

ABSTRACT:

Background

To study visual processing, it is necessary to precisely control visual stimuli while recording neural and behavioral responses. It can be important to present stimuli over a broad area of the visual field, which can be technically difficult.

New method

We present a simple geometry that can be used to display panoramic stimuli. A single digital light projector generates images that are reflected by mirrors onto flat screens that surround an animal. It can be used for behavioral and neurophysiological measurements, so virtually identical stimuli can be presented. Moreover, this geometry permits light from the projector to be used to activate optogenetic tools.

Results

Using this geometry, we presented panoramic visual stimulation to Drosophila in three parad
