Wikipedia agrees there are spiking and non-spiking: https://en.wikipedia.org/wiki/Biological_neuron_model https://en.wikipedia.org/wiki/Biological_neuron_model Not all the cells of the nervous system produce the type of spike that define the scope of the spiking neuron models. For example, cochlear hair cells, retinal receptor cells, and retinal bipolar cells do not spike.
