Adya (2nd year MPhil Scholar) presented his seminar on Neurophysiological basis of EEG, EP and ERP.
He gave a quick historical overview beginning from Ancient Greece, work by Richard Caton from Liverpool in 1875 and the work by Hans Berger in 1925 with the first EEG recording. He then explained the dipole formation due to changes in ionic concentration, impact due to volume conduction and challenges in source localization so far. He then spoke about the referential and bipolar montages and quantitative and qualitative analysis approaches. Signal amplification and artifacts during recording were also covered.
Adya discussed the EPs and their corresponding anatomical landmarks and the ERP signals and testing paradigms with special focus on contingent negative variation. He also touched upon MEG functioning. Finally he mentioned about the current areas of EEG research from clinical (like epileptogenesis) to brain machine interfaces.
There was much animated discussion during the seminar about predominance of gamma and delta signals and their implications.
