a The symbol ‘−’ indicates the absence of a connection/interaction, ‘(+)’ indicates an inconsistent connection/interaction, ‘+’–‘++++’ indicates increasing density/strength of connection/interaction. The connectivity data represent the best approximation to selectivity by including only studies where single cells were filled intracellularly 1Anderson et al., 1994; 2Callaway and Wiser, 1996; 3Gilbert and Wiesel, 1979; 4Gilbert and Wiesel, 1983; 5Gottlieb and Keller, 1997; 6Zhang and Deschenes, 1998). However, constraints are that: (i) data are derived from visual and somatosensory cortex of rat, cat and monkey; (ii) some studies are conducted in vivo, some in vitro; (iii) in most studies the bouton distribution was not shown; and (iv) for layer V and VI the table is biased; e.g. for layer V, it focuses on pyramidal cells of Gilbert and Wiesel (1979), which seem to be similar to the intrinsic bursting-type pyramids in rat. However, if one would represent the more frequent regular spiking-type, this would possess more axon collaterals in supra- and fewer in infragranular layers (Chagnac-Amitai et al., 1990). For layer VI, thalamically projecting cells are preferentially shown (non-thalamically projecting cells seem to have a differently organized axonal arbor; Zhang and Deschenes, 1998). .
