Qualitative Electrotonic Comparison of Three Classes of Hippocampal Neurons in the Rat
Mammalian neurons have traditionally been classified on the basis of morphology, but the functional implications of morphology depend also on the biophysical properties of membrane and cytoplasm. The principles that underlie the relationship between anatomy and biophysics on the one hand and neuronal electrotonus on the other are well understood (Rall, 1977; Jack et al., 1983). However, spatiotemporal complexity makes it difficult to draw reliable inferences about the dynamics of electrical signaling in neurons from their neuroanatomical appearance and biophysical parameters.
