Neurotransmitters
Captions available
The idea
Neurotransmitters are chemical messengers released into the synapse that carry a signal to the receiving neuron.
In practice
An arriving action potential triggers vesicles to release their neurotransmitter into the synaptic gap.
Where people slip
Neurotransmitters do not carry meaning. Meaning comes from which circuit released them and where they land.
