Hello,
I am hoping that someone will be able to direct me towards the appropriate piece of hardware to purchase.
I am a cognitive neuroscientist, hoping to stimulate a specific area of the brain using Transcranial Magnetic Stimulation. The onset of stimulation needs to be precise (~100ms) and paired with a visual stimulus. We've decided to present a small stimulus on the bottom corner of our computer screen, one to be recognized by a photodiode, and this photodiode needs to send a TTL (something like a Schmitt trigger) to our DAQ box (specifically a Micro1401 from CED).
Trained in cognitive science, I am hesitant to make a purchase as I worry that I will buy a photodiode that does not suit my needs. I am hopeful that someone will be able to point me in the right direction.
Regards,
Simon Kaplan
