The transmitter GABA excites immature cortical neurons because:

The transmitter GABA excites immature cortical neurons because:





  1. immature GABA receptors pass more sodium than chloride.
  2. immature GABA-receptive neurons have a more negative firing threshold than mature neurons.
  3. immature GABA-receptive neurons express many Na+/K+/Cl- co-transporters.
  4. immature GABA-receptive neurons express many K+/Cl- co-transporters.
  5. the opening of GABA receptor channels tends to excite immature cortical networks because of the networks' wiring.
