"morphine within" natural opiate-like moleculeslinked to pain control and pleasure

Learning/ memorymessenger at every junction between a motor neuron and skeletal muscletriggers muscle contraction

Influences movement, learning, attention and emotion
excess of dopamine can be linked to schizophrenianot enough and the brain starts to produce tremors and parkinson's disease

Affects mood, hunger, sleep, arousalundersupply is linked to depression

Controls alertness & arousalundersupply can lead to a depressed mood

Major inhibitory neurotransmitterundersupply has been known to lead to seizures, tremors and insomnia
