the action potential is caused by an electrical signal..but now the next neuron recieves a neurotransmitter..which is a chemical..then how does the signal go furthur??
great video helped me alot but i have another problem that is related to the classification of neurotransmitters and the drugs effecting them like Ach effected by botulium toxin or GABA by allyglycine etc that is very complicated can you tell me an easy way to understand it...plz
@hadooish Glad the video helped. Unfortunately, I don't have a good summary of that at the moment. Will probably get to doing something like that the next time I cover the Nervous System, but that won't be for a while. Hope you are able to find good resources. Do a google search and see what you come up with (if you haven't already).
Hello, I liked your video, it explains things simply and clearly.I have a question though:
When a signal traveling on the axon reaches the synapse a neurotransmitter is released.This can be let's say dopamine or GABA or smth else, and is either inhibitory or excitatory, correct?Then the receiving neuron binds this neurotransmitter with its receptors and sends an electrical signal to the core of the cell, am I correct?The question is what kind of signal is this one - excitatory or inhibitory?10x
@diimtarsh1 It depends on the ion channel it opens. If it opens a Na+ channels, that causes an excitatory signal. If it opens a Cl- channel, that causes an inhibitory signal. GABA is usually an inhibitory Neurotransmitter. Dopamine can be either excitatory or inhibitory. However, they have different receptors that can open different channels that allow different ions to flow in. This can result in an excitatory or inhibitory signal. Hope that helps.
I can't believe how much your videos have helped! I could not make sense of any of this until I watched a few of your episodes! Thank you so much for taking the time to post these videos! I look forward to watching more!
@jmlevins1 Yes, once the synaptic vesicle fuses with the membrane, it releases all its contents. However, all of the synaptic vesicles don't necessarily fuse with the membrane to release Neurotransmitter. Some of them remain in the synaptic terminal. Hope that helps :)
@jmlevins1 In order to release the neurotransmitter, the vesicle actually fuses with membrane. Once it fuses with the membrane, that causes the content to be released, which in this case would be neurotransmitter.
@Skoty6 That's a great question. Yes, exocytosis is the process that is used to release the neurotransmitter from the axon terminal. This isn't the only example of exocytosis, but it definitely is one.
I liked it when students were INTERACTING in the lectures... :( now is alot more boring than before :(

is this the same as exocytosis?
