Introduction

Once stimulus patterns have been defined, the ScanImage Photostimulation module provides two modes of operation for commanding the stimuli.

• Sequence Mode: Output of stimulus patterns in a prescribed order. This is the best option if you know before hand the order that you want to output stimulus groups and you desire a high level of timing precision for the triggering of stimulus output
• On-Demand Mode: Random access output of any stimulus pattern at any time. This option is best for experiments that need the flexibility to select which stimulus to output during the experiment in response to experimental conditions
