Which of the following electrical events is characteristic of inhibitory synaptic interactions?

#Part-B Specialized Branches in Biotechnology
  1. A neurotransmitter agent that selectively opens ligand-gated chloride channels is the basis for an inhibitory postsynaptic potential
  2. Because the Nernst potential for chloride is about −70 mV, chloride ions tend to move out of the cell along its electrochemical gradient
  3. A neurotransmitter that selectively opens potassium channels will allow potassium to move into the cell
  4. An increase in the extracellular sodium concentration usually leads directly to an inhibitory postsynaptic potential
