FIGURE 36. Geometry in an interaction
network of cell assemblies.
Fig. 36 sketches a large interaction network, confined to volume V ,in
which a certain portion has been cut away in order to make clear the geo-
metrical situation. We fix our attention on elements in the vicinity of point
r 2 and determine the contribution to their stimulation from other regions of
the network. We consider in particular the contribution to r 2 from the activ-
ity around point r 1 . We proceed precisely as before (see eq. (95)) and write
