Neurotransmitter Receptor

A membrane receptor protein activated by a neurotransmitter.

Binding

The process where a neurotransmitter attaches to its corresponding receptor, triggering events inside the cell.

Membrane Potential Change

The electrical potential across a neuron's membrane, which can be altered by ion flow through channels opened by neurotransmitter binding.

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.
