Answer #1
  • Inhibitory neurotransmitter is a type of synaptic potential, it will decrease the production of action potential by post synaptic potential.
  • Inhibitory presynaptic neuron release neurotransmitter that bind on post synaptic receptors and make change in the permeabilty of post synaptic neuronal membrane.
  • An example of inhibitory neurotransmitter is GABA,
  • GABA receptors are typically open channels, which are selectively permeable to chloride ions.
  • when these channels are open, more negatively charged chloride ion move across the membrane, due to electrochemical driving force, chloride are forced to move into the cell and causing a hyperpolarizing inhibitory post synaptic potential.

After switching the cells to a calcium-containing medium, they still do not release neurotransmitter when stimulated.
