The Four Happiness Neurotransmitters and Your Brain. Mesolimbic dopaminergic and serotonergic pathways. If your high in Seritonin, youâre positive, confident, flexible, and easy going. If youâre sinking in Seritonin, youâll tend to become negative, obsessive, worried irritable, ad sleepless. If youâre high in Catecholamines (norepinephrin, dopamine, and adrenalin are in this group), youâre energized, upbeat, and alert. If your Catecholamines have crashed, you can sink into a flat, lethargic funk.
1 The Ca 2+ , by binding with calmodulin, causes vesicles filled with neurotransmitter to migrate towards the presynaptic membrane. 2  The vesicle merges with the presynaptic membrane. 3  The presynaptic membrane and vesicle now forms a continuous membrane, so that the neurotransmitter is released into the synaptic cleft. Autoreceptors: Receptors for a particular neurotransmitter are located on the presynaptic membrane that act like a thermostat. 2  When there is too much neurotransmitter released in the synapse, it decreases the release of further neurotransmitter when the action potential arrives at the presynaptic membrane.
