Comparison of the effects of neurokinin-3 receptor blockade on two forms of slow synaptic transmission in myenteric AH neurons

AH neurons are intrinsic sensory neurons of the intestine that exhibit two types of slow synaptic event: slow excitatory postsynaptic potentials which increase their excitability for about 2-4 min, and sustained slow postsynaptic excitation which can persist for several hours, and may be involved in long-term changes in the sensitivity of the intestine to sensory stimuli. The effects of the neurokinin-3 tachykinin receptor antagonist, SR142801, …
