Thx! Giving myself crash course on eeg to be able to understand elderly parents test results (brain hemorrhage, neurologist monitoring for seizures). Your videos very helpful even to novice with no medical background. I am easily able to understand everything you've taught, as you present it so effectively. Been watching many of your videos.

This is one of the best online EEG resources I have come across!

Thank you for this. I just taking a crash course in neuroanatomy and couldn’t wrap my head around this concept. You simplified it soo much! Thank you!

Always practice fundamentals!

Thank you for what you're doing Sir. Much appreciated !

OUTSTANDING

Thank you! from Brazil: Obrigada!

This was awesome, you eloquently explained. Thank you

im a desginer trying to use eeg in my research. your videos are extremely helpful

Well explained thank you sir

Thankyousm for this lecture 🙏🏻

brilliantly explained !!!!

This is the best explanation, thank you so much!

It was a very lucid presentation, thank you Sir.will you please explain the dipole concepts and types of dipoles and their importance

Excellent video!!!!

Your videos are short and very informative, I think you have to make more videos, the animation is very nice ,many thanks.

Thank you. A very good tutorial that has helped me to understand more.

Amazing keep going❤️❤️❤️❤️❤️❤️❤️

Well explained thank you

Thank you so much

Thank you for this helpful video : )🤩

Thank you!

Спасибо, очень полезно!

Amazing video really and very clear! thank you so much for sharing knowledge!

Thank you very much, very helpful :)

Truly Amazing 👏

Thats really good

Nice use of Comic Sans!😂🤣

Thankyou so much sir!

God bless you Thanks for the info :)

thanks for sharing🌺🌺🌺🌺

thank u

ultra bien expliqué

Can you please do a tutorial on the ACNS 2021 critical care EEG terminology as well?

Simplified

Explained in nutshell.

just a comment: from your explanation your IPSP dipoles are surface negative and your EPSP dipoles are surface positive with current consequently flowing in opposite direction in their respective dipoles. how can then their potential summate in this case? will they not cancel out each other? to my understanding these dendrites should be first radial and their dipoles be either surface positive or negative all together to summate and be recorded. perhaps you should have added that the IPSP electrochemical changes are distal and the EPSP are proximal with opposite sinks and sources. the electrode being unable to discriminate what comes from IPSP and what comes from EPSP, but both their dipoles must be surface positive or negative otherwise their potential will cancel out and nothing will be recorded by the scalp electrodes. Can you also add that the potential that is recorded comes only from the electric field created by the charge of the dipole facing the brain surface whether positive or negative, the opposite charge of the dipole if the dipole is radial is facing the inferior part of the brain and is therefore not possible to be recorded by scalp electrodes on a routine scalp EEG recording.

how does the extracellular current "flow" ? inside a cell, there are axons for that, but how is it in the extracellular area ?

What can protect or block our EEG waves?

Does the secondary current represent the actual moving of positive ions to the negative charged pole?? Does the sodium for example in reality travels along these lines?

Thanks. It was helpful. Hey could you clear my following confusion? We know that ERN is sharp negative potential observed corresponding to an incorrect response in tasks. For example, there is two button, red and green. Now, I am ordered to press 'green button' but I pressed 'red button' by mistake. As a result, there will be sharp rise in potentials which we call ERN right? However, say I am ordered to press green button, and I pressed green (correct response) but the green button is not working. As a result, will there be any rise in potentials? If yes, can we call that ERN as well? Because in the second case, my response was correct but the error was in the machine, but I may get excited after not seeing the expected result after pressing a button that is malfunctioning.

So is the wave we see in the EEG a result of the extracellular polarity switching back and forth between negative and positive due to fluctuating levels of IPSPs and EPSPs being detected by both electrodes in the channel?

Hello, realy apreciate your effort, .i realy want to know about you, whi are you , plz introduced yourself.
