Action Potential | Graded Potentials

In this video, Dr Mike explains everything you need to know about how neurons send signals via action potentials!
He also discusses different types of graded potentials including;
- excitatory postsynaptic potentials (EPSPs)
- inhibitory postsynaptic potentials (IPSPs)
And what role neurotransmitters like glutamate and GABA play!

    You have no idea how much your videos helped me. I'm a slow learner and need repetition, and your methods make everything so clear. I can rewatch your videos and get confident in knowledge. I graduated my program with a 4.0 and I think largely thanks to having access to your videos. Thanks SO much.

    I noticed that KZread is featuring this video. Normally I wouldn't care............ .................BUT............"Action Potential" is probably Drs Matt and Mike's best video. Action potential is almost never explained clearly. I've watched many videos on it, and they're almost always bewildering. I was bewildered by action potential........until I watched this INCREDIBLE VIDEO. Made me a fan forever.

    Excellent work! Loved this lesson; brilliantly structured explanation. 1 question: Do positive sodium or potassium ions get attracted towards negative areas due to opposing charges or move away from each other by same change repulsion? Same outcome but subtely different reason? And I read somewhere that only small numbers of ions need to move to cause these charge changes?

    Vesicles containing the neurotransmitters actually fuse with the membrane of presynaptic neuron and "dump" the neurotransmitters outside into the synaptic cleft, and that's how they diffuse across, until they reach postsynaptic receptors. I know you are long finished with your exam but hopefully this response can help someone else. FYI ... vesicles can't leave the membrane which is why it's considered exocytosis - "exo" - outside, "cytosis" - cell

    I am not sure about any rare cases. However, based on the definition, if AP occur, it should be a depolarizing period before the AP can occur and it means the cell is being experienced EPSP. If it strong enough, the summation of these Graded potential (EPSP) such as the appearance of Glutamate then enough positive so become AP. Otherwise, if there is the appearance of GABA, the neutron is experienced IPSP, it means the cell becoming more negative and far away from threshold to be depolarizer so AP cannot occur. And AP characteristic is “all or non”, which means fired or not fired. You question about if EPSP AND IPSP can happens at same time or not, I believe the same time if EPSP and IPSP is during the summation of GRADED Potential, if 2 EPSP OCCUR WITH 2IPSP, then it will be canceled out and no AP occur! This is my opinion based on what I understand! If you have more idea about it, please correct me!
