It is not clear what you are referring to when you mention "the different ones" in your question. However, I will provide some general information about how neurotransmitters work in the brain and their role in learning, if that was the topic you were referring to. If not, please clarify in your next responce. 

Neurotransmitters are chemicals that are released from the terminals of neurons into the synapse, the small gap between neurons, to communicate with other neurons. There are many different types of neurotransmitters, each with unique functions and effects on the brain and behavior.

Neurotransmitters can have either an excitatory or inhibitory effect on the neurons they target. Excitatory neurotransmitters increase the likelihood that the target neuron will fire an action potential, while inhibitory neurotransmitters decrease the likelihood of firing.

Neurotransmitters play a crucial role in learning and memory. For example, the neurotransmitter glutamate is involved in long-term potentiation (LTP), which is the strengthening of synaptic connections between neurons that is thought to underlie learning and memory. Dopamine is another neurotransmitter that is involved in reward and motivation, which can influence learning and behavior.

Other factors that can influence learning include genetics, environmental factors, attention, motivation, and prior experience. For example, genetic variations can affect how individuals respond to different types of learning experiences, while environmental factors such as stress can impair learning and memory. Attention and motivation can also affect learning, as individuals who are more engaged and interested in a task are more likely to learn from it. Finally, prior experience can also influence learning, as individuals who have more prior knowledge or experience in a particular area may be able to learn more quickly or effectively than those who are new to the subject.
