To begin this question, it is key to understand what a neurotransmitter is, because this is the crux of the question, which is asking which neurotransmitter is important in regards to reward -based learning and drug addiction.
00:13
So a neurotransmitter is a molecule.
00:16
And if you think about a transmission, because a neurotransmitter a transmission, that's going to be a message, right? a phone call, a text, these could all, an email, these could all be on our sit as transmissions.
00:28
So it's sending a signal or message.
00:32
So neurotransmitter follows this definitive understanding of transmission.
00:38
So it is a molecule that signaling something to happen from neuron to neuron.
00:49
So that's going to be post and pre synaptic neurons.
00:59
Right? so that is the first part is understanding that it's a type of molecule that signals and relays messages between the post -synaptic and pre -synaptic cells, meaning you can think of it as the deliverer and the recipient.
01:22
So we are given a few different types of these neurotransmitters, and we need to understand which of them are relevant with reward -based learning and drug addiction.
01:33
So the first one we have is acetylch, which is ach.
01:39
It's commonly denoted as this.
01:45
And acetych acetylcholine, this is most significant function, sorry, is for muscular function.
01:58
This is going to be found in that neuromuscular junction.
02:04
So between the motor neuron and the, the, the neuron that's going to be relaying that signal for a muscle to contract.
02:13
So this is going to be evolved heavily in muscular contraction.
02:16
When a taser is at work, or if we have tetanus, which could be induced, of course, by a taser.
02:23
This is going to be when we have a lot of acylcholine in the neuromuscular junction, it is unable to be reuptuk.
02:30
So your motor neuron is constantly getting the signal, the message, to contract.
02:37
And that's going to be relating to the electricity from the taser, which we don't need to get into.
02:42
I'm just demonstrating that this is not related to reward -based learning and drug addiction.
02:50
So then we have serotonin.
02:55
I could just use red.
02:56
Don't have to use christmas colors, i suppose.
03:00
Just keeping it consistent.
03:02
We have serotonin.
03:04
We have option c, which is dopamine.
03:09
And maybe these are sounding familiar to you.
03:11
Maybe not, but it's nice to understand some context because a lot of research or pharmaceutical agents are in relation to these different neurotransmitters...
