Thank you for your great work!!!

Glad I found this video. Thank you!

[@kruthi.bbasappa1300]

what about calcium and chloride channels in epsp?

[@prodigy8808]

awesome explanation. thank you!

[@drcustomizer]

Where do I find that spider diagram/mindmap of (synaptic transmission and integration)?

[@jcoleCRNA]

awesome video. thanks!

Her voice sounds like Janice's Voice in F.R.I.E.N.D.S

[@andylenton4407]

Mohammed Mdadha I was wondering who it reminded me of

[@norac5468]

thank you i was wondering who it sounded like

[@thomashatch463]

Very helpful, thanks :).

[@pranavsopory]

EPSP is not explained correctly. Slow EPSP is caused by Gq type mAChR (M1, M3, M5). Gq type acts via PLC pathway, not cAMP

[@sonia549]

Oh my god.Thank you so much!!!

[@mackleswimbaits]

BRAVO!!!

[@s9lupe1]

This was so well explained. THANK YOU!!!!

[@nerdnerd4945]

[@munadizzamanpulok329]

good work

[@f6m846]

Thank you!

[@fathimareema2694]

well explained .

[@Daemon_intellectualis]

Is it -55 or -65 mv? According to Pinel's Biopsychology 7th edition, the threshold is around -65 mv. I would appreciate if someone would help me clarify this a bit... great presentation btw !!!

[@torikulislam8753]

-55

[@fatfighterxDDD]

thanks.

[@shahadshaig6141]

Thank you but I think there is something don't clear for me if the exitatory postsynaptic potention from what I understood is facilitate the action potention occure then when and how action potention occure ?? ...sorry for bad language 😅

[@sexyscientist]

Very first action potentials are generated due to external environment.

[@sexyscientist]

Perfect @1.5x But my question it, how we measure it?

[@briwilbarn]

Very helpful. Found myself shouting answers a la Dora the Explorer

[@Kongfuupanda]

My textbook says EPSP is fast and IPSP is slow.

[@sexyscientist]

Please reread your textbook. There is some misunderstanding.

[@ab6ixblindforloveismyultja641]

4:50

[@smbdcry]

I have to speed 1.5x to watch, but this is informative.. new vocabulary is killing though, lol

[@angelafulton8353]

[@sakshishopaholic]

Nice video but i was annoyed because of your nasal voice

[@Grecco202]

Sakshi Jain the more irratating the voice, the less likely you fall asleep :D

[@I3ZOZz9]

no it was GREAT* vid and attractive voice but regardless of what u think, you shouldn't talk shit while she is doing her best to explain you didn't even say a proper criticism.
