Dot Experiment Fundamentals & Resources

Next steps:

• Make dot animation continuous
• Add instruction screen before main loop
• Implement auditory stimuli
• Send triggers from program to EEG to time lock stimulus presentation
• Be able to analyze all dot times + audio stimuli presentations to ensure correct frequency
• Find video for "naturalistic" visual stimuli presentation
  • How to implement video in python?
  • How will we track the frequency of water drops
• Be able to input the frequency?
• Set up background as fullscreen black window (animation will be in smaller white box)

Important Info:

• Monitor will be a CRT monitor
• Code will be run on a PC
• Communication with EEG is USB-to-serial port (exact info here)

My Frequencies:

• 1.5 Hz (2 syllable units)
• 1 Hz (3 syllable units) Apparently this is more like 1.1 Hz
• 0.75 Hz (4 syllable units)
