Neurotransmitters
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Neurotransmitters are chemical messengers released into the synapse that carry a signal to the receiving neuron.
Show
An arriving action potential triggers vesicles to release their neurotransmitter into the synaptic gap.
Watch for
Neurotransmitters do not carry meaning. Meaning comes from which circuit released them and where they land.
