Document Summary
Has prominent role in learning and memory by strengthening synapses. Release from motoneurons causes muscle contractions in pns/cns. Damage to cholinergic neurons seen in alzheimer"s disease. Causes you to stop move, can stop your heart or lungs. Food poisoning caused by toxin in bacteria. Dopaminergic neurons located in the brainstem and involved in motor control. Pathway stimulated by pleasure associated with food, sex, money and addictive drugs. Reuptake blocked by cocaine, amphetamine (stimulants like meth), and methylphenidate (ritalin) Serotonergic neurons located in the brainstem, send axons widely throughout the brain. Involved in regulation of mood, eating, sleep, dreaming, pain. Mimic neurotransmitter, replace them and activate postsynaptic receptors. Reuptake inhibited by ssris (serotonin-specific reuptake inhibitors) Inhibits serotonin reuptake, increasing release of serotonin, causes a depletion of serotonin that can take weeks to restore, often experiencing depression after. Opiate drugs are agonists (derived from poppies)
