11. Conversely, G protein-coupled receptors are neither excitatory nor inhibitory. 12. This phenomenon is known as an excitatory postsynaptic potential ( EPSP ). 13. Transmission of an excitatory signal involves several steps outlined below. 14. There have been numerous reports of excitatory GABA A receptors. 15. Stimulation of aberrant mossy fibre areas increases the excitatory postsynaptic potential response. 16. These receptors mediate excitatory neurotransmission and are critical for normal synaptic function. 17. Counterintuitively, KCC2 has also been shown to colocalize at excitatory synapses. 18. The spatial summation of an inhibitory input will nullify an excitatory input. 19. The release of excitatory neurotransmitters is reduced, limiting intracellular calcium accumulation. 20. We do not even know whether the synapses are inhibitory or excitatory .
