Action of Neurotransmitters 

This is an excellent video! I'm a very old person going back to school, and thank goodness for the sharp cookies out there like you kids. I actually understand it and I'm able to retain it. Good job, and thank you!

It's hard to find a video with a good, clear explanation. I am happy for finding this great video of yours. Helps a lot

thank you 💝

Marvelous :D

Good thankyou

Get rid of the disturbing entry music.
