Comparative Electrobiology of Mammalian Central Neurons

  • Rodolfo R. Llinás

Abstract

In assessing the impact of the in vitro analysis of CNS function, especially in mammals, one issue has become clear; mammalian neurons are endowed with a large and intricate set of ionic conductances. The intricacy of these conductances relates not only to their ionic specificity, their voltage dependence, and their modulation by neurotransmitters and neuropeptides, but also to their location on the soma-dendritic regions of the neurons. This realization has forced all of us to reexamine the levels at which the rather involved interactions between neurons actually occur. For many years, most of the complexity demonstrable electrophysiologically in different regions of the nervous system was assumed to be produced by the synaptic interactions, i.e., the neuronal network. However, it is evident, following the development of the in vitro preparations, that much of the electrophysiology encountered in mammalian neurons does not derive necessarily from the attributes of networks but, rather, from the intrinsic electrical properties of the cells themselves.
