SYNAPTIC TRANSMISSION IN THE CNS; PART 1 by Professor Fink

This is Part 1 of Professor Fink's Video Lecture on Synaptic Transmission in the CNS. In this Lecture Professor Fink describes how the sum of excitatory (EPSP) & inhibitory (IPSP) local responses in a neuron determines whether or not it "fires off" an Action Potential. Reference is made to Spatial Summation, Temporal Summation, and Excitatory Neurotransmitters, including ACh, Catecholamines, Dopamine, Norepinephrine & Epinephrine.

simply excellent lecture :) thank you sir.

[@christophz.5361]

Thanks for that lecture. It was great and it caused me to order a Pizza.

[@sprognosisj8924]

This lecture made me hungry for pizza :)

[@browniedlux]

Excellent lecture Prof! Very clear explanations and great enthusiasm! Very helpful

the decision analogy is incorrect. Excitatory and inhibitory neurons in the CNS thinking matter are necessary for computation. If you had less of one vs the other, your thinking ability would be reduced. It would not be about making decisions in one or the other direction, but reduced computation power. The reason is you need positive and negative numbers for general computation ability. It's the same in AI (neural networks).
For other neurotransmitters in the body, the idea is correct of course, inhibitory presynaptic reduces pain, heart rate etc depending on the receptors etc. But those neurons are very simply connected, like opening or closing a gate.

[@professorfink]

Very Good points, Rene. However, as I point out in the lecture, it is believed (currently) that certain (not all) behavioral disorders are associated with either excess or deficiencies in excitatory or inhibitory neurotransmitters. And many of the psychotherapeutic drugs act (at least in part) in raising or lowering neurotransmitter levels.

@@professorfink if I had to guess, I'd say that nt imbalance is only a local symptom rather than a cause, and that a more likely cause is energy related insufficiency pertaining to calcium pumps not getting enough ATP. Calcium is the most expensive pump, and most of the energy in the brain is spent on pumping electrolytes. Calcium signals pervade everything in the cell and neuron and signals need to be cleared asap or things go haywire. Unlike muscle cells you can't really downregulate energy consumption in the brain so presumably things would start to get out of balance.

simply awesome! " The voice" is hilarious! Thank you so much.

Another difficult subject, clearly and meticulously explained by the internet’s best teacher, and then hammered home with the hand clap. Hey Professor Fink, have you ever heard of Chuck Berris?

[@raghuvaransivaprakasam8294]

Hello sir, I am Raghuvaran Physiology faculty from India. Your lectures are really fantastic. But I have a doubt in Gibbs donnan equation can you make vedio for that sir..

[@handsmcfadden6636]

Thank you! I find it a little hard to find which order some of the videos go. Is there an easy way to find that out. Thanks again for making this so accessible!

prof you are the best! really usefull and nice lesson! thanks to share it. good luck.

[@Ammerlaan88]

these videos are brilliant, so useful! Thank you so much Pro. Fink!

[@bless1012]

Professor Fink is a beautiful man, and handsome too :D

[@nicholasdesnoyer8505]

I just ordered the hard copy from the book store. I noticed that the Pharm lecture manual is only available in digital format. Any Idea when it will be available in hardcopy?

[@professorfink]

The “hard copy” of the Pharmacology Lecture Outline CAN
BE purchased. Please e-mail Mr. Nilhson
Zelaya, in charge of sales at the WLAC Bookstore. His e-mail is: [e-mail]
He can tell you the cost.
