Neurotransmitters/neuromodulators and five major neurotransmitters
What is a neuromodulator?
A chemical substance that regulates the activity of neurotransmitters at the synpase (it controls the strength of pain occuring) e.g. If your brak your leg, there will be heaps of neuromodulators trying to get to the CNS to tell you OUCH!
What is a neurotransmitter?
A chemical released by the synaptic button (when a neural impulse reaches the end of an axon)
What are two effects that can occur between neural impulses?
It can be inhibitory (blocks the postsynpatic button neuron from firing) OR it can be excitiory (stimulates the neural impulse in another neuron)
