Webb5 maj 2011 · Transmission from the ISNs to the motor neurons is via fast excitatory synaptic potentials (EPSPs, lasting about 50 ms) mediated by ligand gated ion channels and via qualitatively distinct slow EPSPs (lasting 3–120 s) mediated via G-proteins coupled to second messenger pathways (for review see [14] ). Webb30 sep. 2004 · The slow EPSP was accompanied by an increase in cell input resistance as measured by comparing responses to hyperpolarizing current steps applied to the cell before and during the EPSP ( Fig. 1D ). As illustrated in Fig. 2A, the slow EPSP was not affected significantly by the metabotropic glutamate receptor antagonist (+)-MCPG …

WebbIn the sympathetic nervous system, preganglionic neurons excite postganglionic neurons through NACHRs to produce an ionotropic response However, the postganglionic neurons also contain metabotropic acetylcholine receptors (M1, Gq- coupled), and activation of these receptors provides a slow EPSP that slightly depolarizes the resting potential. WebbThese three responses can also be distinguished pharmacologically: the fast EPSP is mediated by a nicotinic acetylcholine receptor, and the slow EPSP by a muscarinic acetylcholine receptor.
WebbThe Neurotransmitters: More than 50 chemical substances function as synaptic transmitters. These chemical substances can be grouped into; Small-molecule (rapidly acting transmitters) and Neuropeptide (slowly acting transmitters or growth factors). The small-molecule, rapidly acting transmitters cause most acute responses of the nervous …
