سومین کارگاه پردازش سیگنالهای مغزی

The 3rd workshop on EEG signal acquisition and processing was held from 4th to 6th January 2017 in National Brain Mapping Laboratory (NBML) in Tehran

About 50 participants including researchers and  Masters and PhD Students in various related fields was attending the workshop . In the first day of this three day hands-on workshop, participants got familiar with EEG signal acquisition  and processing, ERP and Evoked potential extraction and protocol design  based on gtec (www.gtec.at) software and hardware products.
