Webb28 jan. 2014 · A model of the recurrent network of intrinsic sensory neurons identified important control mechanisms to prevent uncontrolled firing due to positive feedback and that the interaction between these control mechanisms and slow EPSP s is necessary for the networks to encode ongoing sensory stimuli. WebbAs has aleady been described in Chapter 3, transmission in sympathetic ganglia results in the generation of the fast excitatory postsynaptic potential (EPSP), slow EPSP, late slow EPSP, and slow inhibitory postsynaptic potential (IPSP) of ganglion cells (cf. Koketsu, 1969; Kuba and Koketsu, 1978).
