Document Summary
Dopamine, epinephrine, norepinephrine (peripheral system arousal) , serotonin (ssri for depression increase signaling in serotonin synapses ; also a part of our sleep-awake , melatonin. Glutamate & , gaba (evolutionarily old, almost in every animal"s neural system, simple molecules, single enzyme create them, most common/popular/prevalent excitatory neurotransmitter glutamate and the inhibitory neurotransmitter - gaba) aspartate, glycine. E. g: cholecystokinin, somatostatin, neuropeptide y (is used for feeding system) Only produced in soma, can"t synthesize them. Stomach"s testiness communicate about whether full (neuro communication) Nitric oxide: gas as neurotransmitter , inner gas as singular molecules. Acetylcholine: brain mechanism involved, regulate hunger, what structures are containing each neurotransmitter. Basal forebrain sends acetylcholine projection neurotransmitters all over the brain - - to the hippocampus. Pedunculopontine nucleus and laterodorsal tegmental nucleus (ppt: sleep, wake cycles. Vta(ventral tegmental area: reward pathway (also send to the prefrontal cortex, substantia nigra. Sends to the ventral portion of basal ganglia: help us to determine good things in life.
