Dendritic morphologies exist in all sizes and shapes which are believed to parallel dendritic function. However, currently there is not much known about the neither synaptic integration in distinct neuronal types, nor the different types of integration taking place inside the dendrites (see main text). (A–D) Illustrates four different neuronal types, and, what is know about their physiology (with respect to synaptic integration), computation and coding function [soma shape of the bipolar interneuron modified for display purposes. Scale bar indicates 100 μm. The morphologies illustrated are all downloaded from NeuroMorpho.org (Ascoli et al., 2007) and originally coming from Borst and Haag, 1996; Contreras et al., 1997; Gulyás et al., 1999; Wang et al., 2002, for A–D, respectively).
