Lett. 105, 178102 (2010) - Firing-Rate Response of a Neuron Receiving Excitatory and Inhibitory Synaptic Shot Noise The synaptic coupling between neurons in neocortical networks is sufficiently strong so that relatively few synchronous synaptic pulses are required to bring a neuron from rest to the spiking threshold. Sympathetic neurons can fire in either a tonic or a phasic pattern (Jia et al., 2008; Springer et al., 2015). We analyzed the degree of tonic and phasic firing in neurons isolated from P2-4 SHR and WKY rats and cultured 2-9 days to determine if altered patterns of firing were observed as early as the postnatal period.
