Study Notes
Neurotransmitter Receptors
- Membrane receptor proteins activated by neurotransmitters.
- Interaction with corresponding receptors can trigger intracellular events.
- Influx of ions through opened ion channels alters the membrane potential of neurons.
AMPA Receptor
- AMPA is an agonist for the glutamate receptor, mimicking glutamate's effects.
- Generates fast excitatory postsynaptic potentials (EPSP).
- Activates non-selective cationic channels, allowing Na+ and K+ passage.
- Equilibrium potential of AMPA receptors is approximately +60 mV.
NMDA Receptor
- One of three key types of glutamate receptors.
- Ligands include glutamate and glycine (or D-serine).
- Functions as a 'coincidence detector': only opens in the presence of both glutamate and glycine (or D-serine) while the neuron is adequately depolarized.
GABA and GABAB Receptors
- γ-Aminobutyric acid (GABA) serves as the primary inhibitory neurotransmitter in mature mammalian CNS.
- GABAB receptors are G protein-coupled receptors that modulate ion channels through G proteins.
- Neurons that release GABA are referred to as GABAergic neurons, primarily exerting inhibitory actions in adult vertebrates.
