Dendrite structure
... In some neurons, dendrites radiate in arbitrary directions from the cell body but are restricted to a planar region. This type of laminar radiation (see Table 1.2) is seen in horizontal cells of the retina (Kolb et al. 1994), and in some interneurons of cortex (Parra et al. 1988). Dendrites of retin ...
