NeuroLatency

I created a simple iPhone app to study the cognitive potentials of the human brain (auditory evoked potential P300). I call this application «NeuroLatency».

English is not my native language, so I apologize if something is not completely clear written in this letter.

If you have any question please email to neurolatency@smirnov24.online
