Neuropharmacology Flashcards
Amino Acid NT =
Serotonin and GABA
Catecholamine NT =
NE, dopamine, EPI
Synaptic Neurotransmission Process
AP leads to calcium influx which causes exocytosis of NT vesicles that can act on ionotropic, metabotropic or presynaptic receptors
They then get reuptaken/metabolized, membranes get recycled, dense core granules with neuropeptides come out to release neuropeptides
NT that are reuptaken =
Dopamine, NE, GABA
NT that are metabolized =
ACh and peptides
NT that are reuptaken by glial cells =
Glutamate
Excitatory NT
propagates signal farther to have more action potentials down the line
Inhibitory NT
hyperpolarization and signal will not be propagated any further
Important for drug binding a specific receptor
Hydrophobicity
pKa
Conformation
Spatial arrangement
Ionotropic receptors =
ligand gated ion channels
Define Ionotropic receptors
Release NT causes electrical effects on postsynaptic neuron by opening a specific ion channel
Complex
Metabotropic receptors =
G-protein coupled receptors
Define Metabotropic receptors
Single subunit
Conformation change which activates this family
Serotonin!!!
Glutamate is synthesized from
Glutamine is released by glial cells and broken down via presynaptic terminals
Glutamate is what type of NT
Fast EXCITATORY
Ionotropic glutamate receptors Non-NMDA
Fast depolarization (AMPA and kainate)
Ionotropic glutamate receptors NMDA
Learning/memory
GABA is synthesized from
Glutamate
GABA is what type of NT
Inhibitory
GABA purpose is
Prevent neurons from firing too often and too easily
