Document Summary
2 regions of ach origination: basal nucleus, pedunculopontine nucleus/ lateral tegmental nucleus. Antipsychotic drugs > antagonists, increase reuptake, increase breakdown degeneration of da neurons leads to parkinson"s: neurons can"t make enough dopamine. 2 regions of da origination: substantia nigra- those are the ones that project to accumbens and striatum for motor behavior, ventral tegmental area (vta) Ssris stop the breakdown/reuptake of serotonin > more is left in the synapse > make more receptors to bind all the serotonin. 2 regions of 5-ht origination: dorsal raphe nuclei, caudal raphe nuclei. Monoamine nts share a common structure and cell bodies originate in the brainstem and send projections throughout the brain. Tyrosine, l-dopa, dopamine, norepinephrine: all have similar structure simple step-by-step structure to get from tyrosine to norepinephrine since they share this base structure, they act in similar ways. What is pharmacology? studying the actions of drugs on living organisms. Neuropharmacology drug-induced changes in the functioning of neurons.
